Why need a paste for brake pads. Effective ceramics for brakes. Lubricants for the brake system. What is better ceramics or copper paste. As an example, I will give some lubricant grads of this group.

Copper grease - A fairly common composition in the automotive industry. It is often used at the factory in the process of assembling the car, as well as in service centers during the repair. Copper lubricant, as can be understood from the title, is made on the basis of copper, which has high thermal resistance, which allows it to protect it from welding, wear, jamming and other defects threaded connections. Also copper lubricant is used in other car elements.

Where copper grease is used

Copper lubricant is in demand in various industrial areas:

It is far from full list where copper grease is used.

Properties of copper lubrication

Copper lubricants can provide sufficient electrical conductivity and reduce friction force. They prevent the penetration of water and wash out weakly and evaporate in the process of work. Also copper lubricants understand vibration and noises.

Please note: in copper lubricants there is no lead, due to which they are used for threaded connections.

Copper lubricant has the following set of properties:

• Able to work in a wide range of temperatures - from -50 to +1100 degrees Celsius;
• Retains its properties when applied on the surface from various types of metals - steel, cast iron, bronze, brass, nickel, aluminum, and so on;
• Long retain their properties and do not require replacement;
• Can be used at high pressure testimony;
• Protect the surface from water, salts, alkali, acids and various solutions.

The following advantages of copper lubricants can be distinguished:

We note that the characteristics of the copper lubricant differ, depending on the manufacturer and set of additives used in the composition, as well as from the dispersion of copper. In general, the consistent copper lubrication consists of basic oil (synthetics, semi-synthetic or mineral), fine copper (on the degree of copper dispersion depends on the lubricant, friction coefficient, electrical conductivity, and other parameters), corrosion inhibitors and other additives.

Important: If it is planned to use copper lubricant at a temperature below -30 degrees Celsius, you need to select compositions based on synthetic or polyester base oil.

How to choose copper lubrication

You should choose copper lubricant, first of all, focusing on what it will be used. Depending on this, the lubricant consistency should be selected:

Choosing a copper lubricant for the car, pay attention to the presence of corrosion inhibitors. They are able to extend the life of the lubricant itself, as well as reduce the likelihood of rust formation on the details.

How to apply copper lubrication

It is important not only to choose the right lubrication correctly, but also to properly apply it to work for a long time with the preservation of properties. Need to observe several important rules When applying copper lubrication:

• Apply the lubricant only on the pre-prepared surface. It is important to clean the surface from the remains of past lubricants, dirt, moisture and other things;
• Do not apply copper lubricant with your hands, it is better to use a piece of fabric or brush for this;
• The composition of the copper lubrication is able to penetrate independently into the holes and cracks, due to the capillary properties. Therefore, it is not recommended to remove excess lubrication.

Please note: when processing bearings, it is recommended to perform a host. That is, after applying lubrication to the part, you need to turn the bearing about 10 times in each direction.

This is a logical continuation of my two first articles (pro and). In them, I touched the subject of pasta for brake shoesMany people do not know anything about it and never apply, others confuse this lubricant with the composition for guide and pistons of the caliper (which is extremely not correct). In general, on the Internet, complete confusion, actually I decided to write this material to tell, and why it is all necessary ...

I'll start with what - the lubricants for the caliper and the brake pads themselves are just a lot, they are all different (produced by various manufacturers), and most importantly - carry various purposes. Some without understanding, can handle the front brake system if they are not correctly chosen.

What differences

Actually there are two types:

• For guide and pistons of caliper . This composition is needed for lubrication, in order not to clinic "guides" and other moving elements. Applied for anthers, protects against moisture and overheating not only metal parts, but also rubber elements, pushes salt and sand, etc. That is, it is just an improved lubricant.

• To remove the brake screen . It is also called it for the brake pads themselves, it is applied only on them, and should not be on moving parts brake system. Because it is not lubricated with her appointment, but to fight with temperature and violines. After a while she simply hardens, and if you apply it to moving elements, there are almost embarrassed. It is worth understanding!

This is the global difference between these two compositions - they are not the same! Therefore, if a neighbor gives you a bag without identifying signs (stayed when replaced by him), it's not necessary to put it off immediately where it's not falling. First you need to understand what it is designed for. Also, in the store you need to take exactly the task that you decide now, if you want to remove the screens and apply on the anti-graded plates - this is one thing, if the piston and guides work well, work is different.

I also want to notice, it can be chained both in large tubes and in small bags, literally at one time.

Principle of operation

Today we disassemble (as you understand) it is for brake pads. So how does it work and at the expense of which removes various sisks and other nasty sounds. Of course, I already have a whole article and even video (you can see by the way).

But I repeat a little.

SO, When the brake shoe is pressed against the disk, then its touch is not 100%, that is, there is no clear parallel pressed pressed. No matter how hard you try, even on completely new "brakes" there will still be a minimum clearance, the piston of the caliper presses only in the middle, so there will be a small "walking" of the surface of the friction material. Exacerbates the situation of wear of the disk surface, the friction layer itself and the other.

In general, with a contact of two planes, a small vibration appears, often it turns into sound oscillations (a certain frequency), which our ear perceives as a creak.

Fight with this can be different methods. Basically, it is impact on the block itself, it is mounted around the edges, they will dial in the middle (not to be noted to the end), or they put anti-slip plates along with lubrication.

It's simple, if the brake system is in order, then we just need to change the frequency of oscillations of the brake pad itself, and the creak will leave.

It is proved that at 50 - 60% of cases, the paste helps + anti-slip plates. But this is not a panacea! If a simple words - Metal part of the pad works like a bell when it goes into a resonance, this is if you want to throw a metal ball on the bottom of the bath, there will be a terrible hum, but if you sit on the bottom of the rubber rug, then the sound will not be almost. So the lubricant works in the same way, it absorbs sound waves, and you do not hear the screens.

That is, the main purpose of just two points:

• Fighting unpleasant sounds
• Disposal of unnecessary heat. By the way, this paste "does not allow" high temperatures to the piston of the caliper

As you can see the tasks are extremely simple. I clarify with the second point, excessive heat to the piston, it is desirable to divert so as not to transmit heat to the very brake fluid, because if it cannot be changed, it can just boil, which is extremely negatively affecting the brakes in general.

What consists of

Of course, the basic formulas are kept secret, this is understandable, all major brands are beating above the production.

However, information seeps on the Internet, the main formulas are only two:

• Based on copper, plus mineral and synthetic substances
• Based on ceramic materials, also plus the mineral and synthetic compositions

Which one is best to say, they work approximately the same - as they say "taste and color"

As applied

Again there are two ways or on the back of the brake pad itself, or on the anti-slip plate.

The main thing is to remember - the layer should not be too thick, as a rule, just a few drops, or thin strips.

It is worth remembering to apply for a friction layer useless! It's just not why. Many newbies can be confused.

Konstantin Dubarev - owner car Kia. Cerato talks about how to eliminate the brake creaking. New branded pads set on Kia Cerato 2006 released, creaked. Konstantin used lubricant, after which the creak instantly disappeared.

In August 2012 It's time to change the front brake discs and pads on my Kia Cerato. 2006 release. Usually, I am not inclined to save on repair, especially if it comes to the reliability of the brake system, so I purchased an original kit for spare parts. After installing and running the brake pads (700-1000 km), I began to notice that the pads begin to creak when braking. And if at first it was about a periodic viper, then somewhere in a couple of weeks the pads were squeak at each braking. In general, I understood that the creak and braking efficiency are little related, but it is very unpleasant to hear.

After having studied the topics of the fight against creak, I stopped using universal lubricants for brake systems. The use of special anti-graded plates I immediately shallow, as they need to be selected under the blocks and the caliper, which means to go to the store again, order, wait, in general, spend time. I also abandoned the use of highly specialized lubricants for brake systems (like copper pastes or lubricants only for guides) for almost the same reason: if you need to serve the caliper, for example, with the next shift of the pads, I will need to provide the mechanics at least two lubricants. Why, if you can do with one tube. So, after applying universal lubrication on the non-working surface of the pads, contacting the caliper when braking, the creaking instantly stopped.

The most interesting thing is that the lubricant was useful to me literally in a week. Making smooth braking on one of the urban intersections, in the driver's mirror of the rear view, I saw the smoke that it was to see how it seemed to me, from the rear wheel arch.

After a few seconds, this smoke leaked into the salon, and I felt the caustic, irritable for the eyes, nose and blood stroke. After that, the car was still drowned, however, during acceleration, and when braking, the car behaved quite sluggish, as if something would interfere with her. In addition, switching gear (automatic transmission) has become less smooth. In the evening of the same day, I naturally turned to my mechanics. He diagnosed the encoding of the rear caliper. In fact, the brake piston stopped working, since the guide caliper climbs. And they exactly "thanks" to the fact that in due time were not properly processed.

Of course, the caliper, I had to be replaced, and this time the universal lubricant was useful for lubricating the guides to no longer scattered.

Expert opinion. Change the pads correctly.

When replacing the pad it is very important to pay attention to the lubrication of all parts of the caliper: guides, non-working surface of the pads, piston, anthers.

Lubazan guide caliper
universal lubricant on synthetic basis

It may take more time than just the usual replacement procedure of the pads, but paying attention to every detail, we ensure our safety and long life of the mechanisms. Disc brakes work in the most severe conditions of high temperatures, which in the friction pair of the disc-block can reach + 500 ° C + 600 ° C. When replacing the pads, various lubricants are used, and the operation of all components of the caliper largely depends on their choice.

Random lubricants

The aerosols are very convenient in applying, but they are not combined with the rubber elements of the caliper, in connection with which their deformation and loss of tightness occurs.

The boot increased by 3 times and lost hermeticity after the use of graphite lubricant.
The use of copper-containing aerosols gives a similar effect.

Traditional lithium or graphite lubricants have oil base And therefore are not compatible with rubber anthers. These lubricants have a low temperature range and quickly burn out. Such lubricants are easy to determine by operating temperature until 200ks.

The so-called "Medickens" (copper lubricants) do not always withstand high temperatures and burn out on guides, provoking corrosion.

Specialized lubricants for different caliper nodes do not imply multipurpose use.

How to choose a lubricant for calipers

When choosing lubrication, it is very important to pay attention to the main characteristics:

• High temperature range
• Nonishness S. brake fluids,
• Synthetic base
• Versatility of application
• Content with rubber parts.

Now that we know the reason and ways to eliminate it - act! When you change the pads, lubricate the guides, piston and non-working surface of the pad, while using universal high-quality lubricant for calipers.

Consider the question is not just about what to lubricate the caliper, but what to lubricate the caliper to avoid big problems in the future.

This is, in fact, a very important topic. And not even because it is brakes and jokes with them they can face deplorable, but because this question has been confused to so much that it is practically not real to choose the right lubricant for the brake caliper. Not even practically - but, in general, not real! Especially if a person faces this for the first time in his life.

I personally passed through it. What to say, if seven of the seven "consulting sellers" tried to sell me a lubricant for guide calipers, which is guaranteed to join the caliper of my car in a couple of months? Because they are not intended for this.

What can not be lubricated caliper

Everyone as one advised me copper lubricants, anti-slip lubricants and a couple of dozen bags and tubes with various lubricants, which are allegedly designed for lubricating the guide toes of calipers. My clarifications that these lubricants are not suitable for this procedure, most often caused surprise and explicitly desire to send me to be misunderstood somewhere else. About lubricant for the piston of the caliper, in general, no one and never heard of them. And where to hear them from? All the same suppliers traded, respectively, all the same.

But there were others who were trying to prove to me to prove to me that the copper lubricant they sell is just designed to lubricate the guide calipers of the brake system. As a proof, it was proposed to study the text on a tube with copper lubricant

If you read not running, but thoughtfully, it will become clear that the lubricant is not intended for brake cylinders and calipers, but to lubricate various fasteners parts that work with high temperatures! Fasteners of the caliper, not the caliper itself! This is very good lubricantbut it is suitable for lubricating bolts exhaust system, threads of oxygen sensors and other fasteners, which, after exposure to high temperatures, is very difficult to unscrew. I use such lubricant for guide pads. Pads !!! And not guide fingers!

It is worth noting that the manufacturers themselves often creep with inscriptions on the packages, which even more in the dead end of the gullible motorists. This problem really has gained massive. In Offline "Sellers-Consultants" clearly do not understand what they advise and sell, and more "instructions" appears on the Internet, how to lubricate the guides of calipers, where copper lubricants are used or, for example, Bremsen-Anti-Quietzch-Paste.

In general, the case is sad and the choice is very difficult. So I decided to show my chemistry set for brake caliper service

This, in my opinion, the only lubricants at the moment, which actually perform their function.

The first in our list will go lubricant for the piston of the caliper - Ate Bremszylinder Paste..

Article ATE 03.9902-0501.2

This is the only lubricant in its kind for this procedure on the market. True, it is not so easy to purchase it, but really. I purchased

She is the most expensive in my set - 200 UAH. For the tube of 185, but it is worth it, believe me.

First, this lubricant is compatible with DOT3, DOT4 and DOT5.1 brake fluids and does not cause problems with rubber seals.

Secondly, one tube is enough to lubricate the pistons of calipers by half of your garage cooperative, which can level a high price, if the next Friday does not bother with beer, but on a lubricant tube

Tubik really not small

Maybe there may be a question - why, in general, lubricate the piston of the caliper?

The most important reasons:

• facilitates the installation of the piston when assembling after replacing seals
• prevents corrosion and piston boiling
• facilitates piston move
• extends the service life of the caliper

For lubrication of the guide fingers of the caliper, the lubricant is best suited Trw.

Article PFG110

Of personal experience I can say that this lubricant does not turn into powder after the six months of operation and the guide fingers remain movable, and the rubber does not change their properties from contact with lubrication.

This lubricant for the guide caliper is also not easy to find. She cost me at one time at 70 UAH.

The tube is not quite large and accommodates only 25 g. Therefore, half a garage cooperative is not enough, but only enough to serve the caliper of his beloved car several times.

Russian text on the tube is also not available

In my opinion, these two tubes must be definitely in the garage.

You can also purchase this lubricant.

Mannol Kupferpaste.

Article 9896.

I lubricate the guide pads and the back side of the pad at the point of contact with the caliper.

What to clear the caliper

As you know, to lubricate the mechanism well, it is necessary to clean it before cleaning it from dirt and old lubrication.

For these purposes, the brake cleaner is very well suited. Not because it is a cleaner that is exactly the brakes, but because it cleans everything well and at the same time it has a small price for a fairly decent amount of 500 ml. And this is too Trw.

Article PFC105.

This cylinder cost me 50 UAH. And I apply it everywhere where you need to clean something

But in such a seemingly simple matter, too, not everything is so simple. YouTube is literally rolled with brake cleaning rollers. Everyone literally sturped on it. All would be good if not one thing ...

The whole meaning of instructive articles and rollers is reduced to the fact that it is necessary to spray the contents of the cylinder at any angle on brake disk and brake caliper. And after evaporation of the brake of your car, they will shine and will be better to slow down, as you wash off all the dirt and dust from the abrasion of the pads.

At these moments, I have a picture before my eyes, as this cleaner flies all the lubricant from the guide pads and other places, and given the fact that most of these cleaners are made of oil, the swelling gum of anthers actively complement this sad picture.

Therefore, my opinion is such that it is necessary to use such cleaners after dismantling the caliper and extracting all the anthers. Only after that, everything is cleaned and wait for the evaporation of the cleaner. Then you can apply new lubricant and install rubber seals and anthers.

All the above, although it is personally my opinion, but I sincerely advise you to listen to it. It seems to me that it will help you avoid many problems and disappointments when servicing the caliper.

Well, of course, the first thing must be followed by anthers, since none of these lubricants can fully perform its function at torn or stretched anthers.

And what happens if you do not notice the woven boot in time

Video - what to lubricate the caliper

All world and smooth roads!

All car systems during its operation must be good. But some attention must be paid to the brakes. After all, often the life of the driver, passengers, other participants in the movement and pedestrians depends on the state of the brake system of the machine. Periodically, it needs to be serviced. This is to replace brake pads, disks, liquids, as well as calipers. For example, lubricant for brake cylinders when maintaining and replacing is simply necessary. We will talk about all this.

Lubrication guide caliper

Before moving directly to the cylinder, you need to deal with its guides. During operation, there is a large amount of heat. This leads to the fact that the compound is often accompanied by tightly. This also applies to the guides that begin to twist. There is nothing good in this, as this may lead to serious consequences. Sweeping contributes to the fact that the pads will be constantly pressed to the disk. This leads to significant overheating of the system. As a result, the pads are burning, the discs become curves. Yes, and the tire in such conditions can easily light up. That is why when servicing a caliper, it is necessary to process guides with special lubricant. What exactly, we will understand this article.

Properties of lubricant for cylinders and guides

Since the node refers to the hard-loaded and in the process of work heats up to 300 degrees Celsius, and with aggressive ride and above, the approach must be appropriate. Lubricant for brake cylinders should have the following characteristics:

It is based on the above parameters, a grease for brake cylinders and guides should be seamless. Fortunately, the assortment is just a huge assortment, so there should be no choice with a choice of work.

Copper lubricant for brake cylinders and calipers

It is the most common and popular among motorists. High temperatures are not afraid and is inexpensive, it makes it so popular. Most often used for processing disks, brake pads, as well as for brackets and other brake system elements. It is worth noting what is applied to the opposite side of the product. If these are pads, then their front side should not be covered with any lubricant, it concerns the disks.

The process of applying paste is also extremely simple. For this, the surface being processed is cleaned from dirt and corrosion. Further, the brush is applied with a tassel and is evenly distributed over the entire surface. It is worth noting that it is sold and in the cans, in this case it needs to be sprayed, after reading the instructions for use.

Basic base for high-temperature lubrication

On the shelves of auto shops are currently just a huge selection. But if you figure it out, then there are only 3 extensive groups:

• mineral base;
• synthetic basis;
• mineral or synthetic basis with a small amount of metals.

If you understand what a lubricant should be used for the brake cylinder, it is best suited that is made on a synthetic basis. This is due to the fact that it is neutral to rubber and plastic products. Consequently, anthers do not eat and is ideal for processing brake piston or guide caliper. The base used gives a number of advantages, such as low evaporation, high temperature threshold, insoluability in water and other liquids. In general, an excellent choice is true, not always budget.

It is much cheaper than lubricant for pistons of mineral brake cylinders. But it is still better suitable for guides, since it is able to withstand temperatures from -45 to +180 degrees Celsius.

Lubrication with the addition of ceramic particles

About new Developmentwhich has already managed to gain popularity. It is expensive, but the stated benefits are very encouraging. Raising performance characteristics Lubricants are achieved due to the presence of a small fraction in ceramics. At the moment it is one of best methods Protection of brake cylinders and their landing places from corrosion. In addition, the processed nodes exclude the possibility of sharp temperature drops, the formation of dirt and dust on the surface.

Despite high cost Such products, it is extremely popular among motorists. It can be used as a lubricant that is less loaded compared to the front. Among the most popular high quality producers can boast a firm "Liquima Moli". Well, now we go further and consider some more extremely important points.

How is the maintenance of the brake system?

Often, the complex lubricant is recommended when replacing brake pads or disks. There is nothing difficult here. First inspect the condition of the guides. We clean your fingers and planting places from rust and process a certain amount of lubrication. Copper, graphite, etc., is suitable for piston, then the lubricant is needed to reduce friction and corrosion protection. The surface of the part is desirable to handle a small amount of ceramic lubrication. It effectively protect the surface from rust.

An extremely important detail is that it is worth regularly checking the state of the anther. If he is torn, no lubricant will help. First you need to replace and then lay the lubricant material. In addition, it should not be too much, as it will begin to squeeze through anthers and cuffs, which is not good.

Many experts recommend not to save on lubricants For calipers and buy only proven products. For example, the optimal lubricant for the pistons of brake cylinders on silicone basis. It is completely safe for anthers and at the same time is high-temperature. Consequently, it works efficiently both in the winter and summer.

Car service specialists often do not fulfill their direct duties. For example, the calipers and guides must be cleaned when replacing the pads, but no one does. Therefore, it is better to do it yourself, especially since there is nothing complicated and even a beginner will cope. You should not neglect the maintenance of the brake system, but also to look there every 500 kilometers of the mileage also does not make sense. Inspect everything during the replacement of brake pads.

What lubricant is better to take?

It is advisable to use different types of lubrication depending on the workpiece. For example, the guide caliper is perfectly suitable for it is inexpensive and withstands high temperatures. Protects metal products from corrosion and prevents stripping. One of the most available options - TRW products.

The optimal lubricant for the pistons of brake cylinders should be on silicone or ceramic basis. Best manufacturer In this regard - FEBI. Cheap and angry. But anti-graded Liqui Moly. Not recommended for bookmarking the piston boot, as it may cause the destruction of the rubber seal.

The anti-graded paste is great for processing the brake pad plate and holding a bracket. Usually it ends with it. Remember that the lubricant of the brake cylinder cylinder should not be performed with pasta that corrupt rubber seals. This can lead to the complete destruction of the piston and the caliper.

Let's summarize

As you can see, there is nothing complicated in the maintenance of the car brake system. But at the same time it is extremely important to regularly lubricate all elements of the caliper that each time they work at high temperatures. Pay attention to the dust of the guide fingers. They are also subjected to wear, resulting in a rather unpleasant knock on irregularities. It happens due to the fact that the finger is freely dangling in the seating area and is not held with a plastic sleeve.

As for lubricants, now they are simply a huge amount. Any paste for lubricating brake cylinders, if it is designed for this, suitable for use. It is not recommended to lubricate the parts of the brake system by simple motor Oil or solidol, etc., all this will not lead to anything good.

Many of the brake system details with due service are capable of serving 200-300 thousand kilometers and more, it concerns calipers, guides, pistons, etc. Pads and wheels are more consumable, but it is also advisable to watch them too much. All this will allow you to feel more confident to feel behind the wheel and to know exactly that the brakes will not let it down, because everything is lubricated and checked there. Often, the problem is found precisely with the jamming of the guides and the tight stroke of the brake cylinder, which occurs in 90% of cases due to the insufficient amount of lubrication. If, with each replacement of the pad, lubricant for anthers of brake cylinders will be used, then you will not know the problems with the braking system of the car.
