Replacing the brake fluid Toyota Corolla. Replacing the Toyota Corolla brake fluid What is brake fluid

The brake fluid is the flowable element of the brake system of any vehicleThe function of which is to transmit mechanical effort from the central brake cylinder to the wheel. The brake fluid directly affects the level of safety during operation and the distance of the stopping path.

According to service book E150 replacement brake fluid Every 40,000 km of run or 2 years of operation should be made. Regular replacement of the consumption is the quality composition of raw materials - as water is accumulated in the "TORROSUM", which reduces fluid characteristics.

The volumetric water accumulation boils when the fluid temperature is achieved 100 degrees, which leads to the formation of a gas cushion, which worsens the transmission of mechanical effort to brake cylinders - the replacement is neglect leads to failure failures, which reduces the efficiency of the system and increases the stopping path of the car.

The main criterion indicating the low quality of raw materials is color: a new liquid has a bright yellow color and with exploit, flown by additives and impurities. Cinnamon substance is true sign In the need to replace raw materials.

Corolla brake fluid is also used in the clutch mechanism - when timely replacement Expendable raw materials also increases the softness of the clutch, which reduces the risk of gear degradation gear.

How to choose brake fluid for Toyota Corolla E150

To buy a new substance is recommended solely from an authorized supplier of Toyota or in dealer Center For a service station: Do not save on the quality of the brake fluid. High-quality "TORROSUKH" must comply with DOT quality - for E150, a substance with marking is suitable:

• Dot4 is a bright yellow substance of aggressive composition, capable of crushing rubber nozzles. The chemical composition of the liquid is distinguished by the presence of additives that increase the elasticity of the substance, which speeds up the transfer of efforts to brake cylinders;
• Dot5 is a yellow substance with an acid tint, a consistency is thick than Dot4. A distinctive feature is the presence of heat-resistant additives, which increases operating temperature liquids - braking efficiency is not reduced until the mark of 115 degrees is reached;
• DOT5 - Liquid with an innovative composition that is poured into cars last generation. The liquid includes a silicone base, which is characterized by weak aggressiveness and increased efficiency.

DOT4 and DOT 4.5 fluids are interchangeable and in the event of a liquid change, the brake system is not required. When replacing the substance on the glycol basis on the silicone analogue of DOT5 washing the system of technical alcohol.

It's important to know! It is strictly not allowed to acquire a substance "on spill" or in non-professional container - the absence of branding and warranty is a direct sign of low quality raw materials.

As the car is operating, the level of the brake substance is gradually reduced, as a result of which the braking efficiency is reduced and the temperature of the remaining fluid increases. Every 2-3,000 km run is recommended to pour a substance to the level of the mark on expansion tank.

How to Pour Brake Liquid: Step-by-step instructions

The procedure for changing the liquid is quite simple and does not require specialized skills - to fill a new substance, it will take to an hour of free time, as well as the presence of a wrench on "8" with a ratchet, hose and dishes for drain. Replacement of brake fluid on Toyota Corolla E150 is as follows:

• To begin with, the car is required to drive on watching pit or subdomain. In the case of subdomains, it is necessary to establish the anti-tart stops under the wheels and additional racks for the spars, fastening the engine;
• Next, we find the expansion tank with brake fluid: on the E150 the tank is located right side Hood closer to the windshield. You can drain through any hose or nozzle - optimal option is a pipe from a dropper with a diameter of 10 mm;
• Then I will lie to the car and find the oil-sliced \u200b\u200bneck, after which we unscrew the lid and begin the draining of the test alternately from each wheel. For a drain, we unscrew the oil sliding fitting and we are waiting for filling the packaging to work out;

It's important to know! In the presence of impurities in working out the brake system of the car is recommended to rinse with technical alcohol or special composition for washing.

To clean the system, it is necessary to spin the oil plug at the bottom of the car and pour alcohol into the expansion tank, after which the brakes by pressing the pedal, and drain the liquid. The number of flushing procedures is directly proportional to the level of contamination of the brake fluid.

• After completion of the preparatory procedures, we unwind the oil-tapping neck and pour a new substance into the expansion tank to the mark;
• Next, in the cabin, pump the brakes by short-term pressing of the pedal and replacing the liquid in the expansion tank to the mark.

After changing the brake fluid, check the condition and efficacy of the brake system at low speeds and, if necessary, pump cylinders when necessary.

In the absence of severe contamination, the fusion test may be useful for household needs: the composition of the substance is perfect for heating a garage or canning tools in order to protect against corrosion.

Every motorist will tell with confidence that brake system - This is the most important element of the safety of the car, which should always function clearly. This system It serves to extinguish the speed or completely stop the car in the process of carrying out the road traffic.

As a rule, most brake systems operate due to the pushing of a special brake fluid, which in turn presses on working cylinders, and they are in the actions of the pad. Periodically, each such system requires replacing the working material, that is, the brake fluid. In this article we will talk about how to correctly replace the brake fluid on Toyota Corolla.

What braking liquid to choose?

To date, there are three main types of brake fluid. Each of them has its own nuances. So, let's wonder each of the types:

• The first view is dot3. It is able to damage the gaskets and gum from genuine rubber and in fact it should not be used in cars with similar pads. Using Dot3, stands special attention turn to the fact that it corrosive car paint.And this means that the ingress of even the slightest drops on the car body is not desirable.
• Second view - Dot4. It has a slightly different consistency, but its chemical composition is also aggressive, as well as at the first species. This liquid is poured into the cars of the last five-year period.
• Third view - DOT5. Most often used on the technique of recent years.

In Toyota Corolla cars, a DOT4 type fluid is used, however, when it is purchased, it is worth looking for an original liquid that is used in the Toyota brake systems.

In addition, when replacing the brake fluid it is necessary to remember that it is impossible to mix different types of fluid. Therefore, producing a replacement, it is necessary to completely drain the produced liquid and only after that fill the new one.

How often change liquid?

As a rule, the frequency of replacement of the brake fluid depends on how quickly the car drives a certain number of kilometers. Therefore, the fluid varies through a certain number of kilometers passed. Find out the number of kilometers through which you need to change the brake fluid from a certain model in technical documentation To the car. Toyota, the Corollas in the technical show states that it is necessary to change the brake fluid every 40-50 thousand kilometers.

Now let's find out why it needs to be changed. High hygroscopicity affects the fluid replacement. Over time, it is able to accumulate moisture, and this in turn leads to the fact that the boiling point of the liquid falls. So 3% of water in the liquid reduces the boiling point of about 30 degrees. In the case of sharp braking in the presence of inside the moisture, the appearance of steam plugs, which worsen the braking of the car, etc.

Phased instructions for replacing brake fluid

Before entering the fluid replacement procedure, you need to drive the car into the garage. When it was done, let's raise the jack of any of the wheels of Corolla. Anyone - because you have to raise each wheel. After raising the part, we unscrew the wheel and put it aside. We removed the right rear wheel in order to be able to better consider the fitting through which the liquid would be merged.

Immediately I want to say that for models that have been driving enough without replacing fluid, a set of new valves will be required, since old can be in disrepair. They are not expensive and during the drain of the brake fluid from each wheel, it is necessary to simply change them. They look like this:

So, we find this fitting. Previously before unscrew it, let's clean carefully workplace. For the ease of its unscrewing, then the VD-40. We take the head on 8, a small knob and twist the valve. As you will see in the photo, no protective caps are no longer there, which means that they are completely clogged with mud. The photo highlighted and signed workplace.

Next, schisming the valve, do not unscrew it. Let's raise the hood and find an expansion tank with brake fluid. Next, open it and turn out from there as much as we can. In the photo you will see homemade adaptation For pumping fluid.

After the liquid is filled and you covered the expansion tank, we take for unscrewing the fitting, usually enough 2-3 revolutions. Previously, it is necessary to prepare a drain hose and a jar. So, proceed to the process of plum.

In order to speed up the process, you can press the brake pedal several times. As soon as you see that the new liquid started to flow, tighten the valve back. If he is old and without gum, we need to unscrew it and screw the new one. It is necessary to do this in the process of leakage of the old liquid.

Before starting the procedure with other wheels, you must make sure that there is still a liquid in the expansion tank and it is located at MAX. This procedure must be made on all four wheels. The most important thing is tightly twisting the new valve and check the fluid level in the tank.

If you are a happy owner of the car Toyota Corolla - consider you lucky. It's not just that it's just good car. Most of the operations on its current service and even minor repairs will be forces. Including - change the brake fluid.

Why need to change liquid

Brake fluid, like any other oils used in the car, absorbs water. Water falls out of the air, in the form of splashes in the gaps of mechanisms, or it can initially be present in low-quality fluids.

During inhibition, the temperature of the liquid rises, and, if it becomes above 100 degrees - water in it can boil. At the same time, a gas pillow is formed, and the brake "flies", the braking will go with the failures. It is very dangerous and fraught with accidents.

In addition, in the car Toyota Corolla, the same fluid is used in the clutch mechanism.

So, if you take care of brakes, you will simultaneously improve the clutch operation - it will work cleaner and softer.

During the operation of the car, leaks constantly occur. Wine this is a leakage of compounds and pipes. Therefore, do not be surprised if the tank is flooded in almost a plug, after 10 thousand kilometers becomes half empty.

When to change

The surest indicator that needs to be changed is a color.

Fresh, unused liquid has a beautiful yellow color. After a long use, it darkens. When it becomes a brown or light brown shade - this is a sure sign that you need to replace. Usually the replacement is made every 10,000 kilometers of the way.

Where to look

Car model E150 and for Toyota Corolla 2008 release brake fluid is filled into a plastic tank under the hood. He is located near windshield, a little on the right. Other models have a tank location may differ. If you can't find it - look in your car's passport or map maintenance. On the tank there are divisions showing the volume of filling it in liters, in some models it is equipped with a lid with a dipstick showing the level.

Tools and devices

To work, you will need an overpass, a waterway-sensor, an observation pit or jack. The last option is the most inconvenient - you will have to merge oil from the system, and it will be easier if the dishes are much lower than the fitting.

You will also need a hose for the fitting. The diameter of the hose is 10 mm, but if not, then you can use a hose from a medical dropper, it can be put on a fitting with some effort. The dropper is sold in the pharmacy and costs about 10-15 rubles. You need to stock up for working out. Its volume should be near a liter, it is desirable to use a glass container that is not extended by oil. The packaging should have a dense stopper so that it is possible to drain and put it on storage - some use it for the heating of the garage.

From the tool, you will need to take the key to 8, preferably with a small handle and ratchet.

Operating procedure

Initially, the car must be put on the flight, jack, lift or observation pit. Then you open the hood and unscrew the tank cover with butter. After that, start draining throughout. Plum order: left rear wheel, right back, then right front and late left front wheel.

To merge oil from the system in one wheel, first remove the plug from the fitting. Then put on the hose on it, the free end to lower the dishes to work. Unscrew the nut near the fitting, should flush the oil. Meril until it stops flowing. Then - other wheels. After you have merged everything, close all nuts.

Then Father new liquid To brake in the tank. You need to cast a little more than half a liter, focus on divisions in a tank. Sit into the salon and 10-15 times press intensely on the car brake. After that, climb back to the car and scroll the oil - unscrew the nut until the oil starts to flow through the hose, then close. So all the wheels in the same order in which you merged oil. After that, put the caps on the fittings, close the tank, the hood and go from the overpass or pit.

Let's summarize

When you buy brake fluid, look at the conditions under which the car will be operated. Its producer can be different, but they all adhere to American DOT standards. What to choose for Russia? The best thing is suitable that has a Dot4 labeling, also DOT4.5, DOT5. If the car of the release of 20 years ago and more, they do not suit due to problems with the resistance of rubber.

With your permission, I quote ELECTROVICA
"The car owners often believe that the brake fluid in their car is eternal and poured once and for all, or simply flashed to produce a planned replacement of the brake fluid provided by the manufacturer. Completely in vain.

There are sufficiently high requirements for the brake fluid, because it depends on the safety of the car on the road. And these are not empty words. Judge for yourself. One of the requirements is the boiling point of the brake fluid. The higher this temperature, the higher the high-quality liquid is considered. The fact is that the working brake mechanisms are heated to a decent temperature even in winter, and in hot weather they can seriously fascinate. Try to touch after the ordinary urban drive disk front wheel. Just be careful. Ai! I warned, carefully! No wonder mountain roads Complete and nearby posters "Tormesi Engine!"

With frequent use of brakes, discs and pads are very hot, after reaching a certain temperature, the braking fluid boils, and the car unexpectedly becomes uncontrollable. It can be argued that with the usual movement in the city it is irrelevant, because there are no protracted serpentines in the cities, and there is no reason to throw liquids. This is true. Boil quality liquid only on started descentBy ignoring the engine braking recommendations.

However, the picture can change much if the fluid has not changed several years. The main reasons are two. First, the brake fluid is hygroscopic, that is, absorbs moisture. Accordingly, the boiling point is reduced. It happens to such an extent that the formed cocktail may rise in a banal plug. Secondly, the brake fluid works as a lubricant in the main and working cylinders, wash the piston-cylinder friction friction products, that is, fine metal dust. The first are the rubber cuffs (the cylinder begins to leak), then sinks appear on the cylinder mirror, and since the liquid has not changed for a long time, and there is a lot of water, corrosion spreads quickly. There is already required to repair the brake system. But it could be avoided simply by changing the fluid on time.

And it is also good if only the brakes have to be repaired, and not to resort to the services of tinsmiths and, God forbid, doctors.

Most cars can simply change the brake fluid every two years or every 40,000 kilometers of the run, which will come before. At the same time, it is not necessary to save and pour the domestic liquid - it serves less, and the mechanisms of the brake system spoils more. The liquid must be bright and transparent. If it is dark and at the bottom of the tank there is a precipitate, do not pull with the replacement of the liquid. Do not forget to rinse the system and thoroughly wash the tank. To see which brake fluid should not be, you can almost on any zhigules with mileage from 20 thousand kilometers. As a rule, before transparency, she is far away.

When replacing there are some unpleasant moments that need to be considered.
1. In the machines with disk (and not only) the rear brakes have a pressure regulator of the rear brakes, and if the machine hangs on the lift, then pump the rear brakes (with a good regulator) may not work.
2. In some machines (for example, Toyota Land Cruiser. In the 80 body) in the pressure regulator there is a grankaya fitting, so it should also be pumped.
3. Pouring it is necessary according to a strictly defined scheme, and not from a long wheel, as often believed. After pumping along the wrong circuit, the pedal will be tough, but the brakes will be slightly wadded, and how much do not download, it will not be better. There is no pumping dance below. Please note that there is a distinction between left and right-handed machines.

Required special tool:

- Caid key to turning out air removal fittings.
- Transparent plastic hose inner diameter 6 mm and a container for collecting the brake fluid.

Former in use brake fluid Repeated do not apply.

Observe the precautions when working with brake fluid, while refer to the subsection Brake fluid .

Brake fluid through the pores of the brake hoses and the ventilation hole of the reservoir absorbs moisture. As a result, the boiling point of the fluid is reduced during operation. With a large load on the brakes, this can even give to vaporization, which reduces the effectiveness of the brakes.

Brake fluid should every 2 years, preferably in spring, replaced with a new one. With a frequent movement in the mountainous area, the fluid must be replaced more often.

One hundred air from the brake system is usually deleted on a special device. However, this can be done without applying the specified device. In this case, the brake system pumps the brake pedal. This requires the participation of the assistant.

If during the removal of air from the brake system, the fluid level is sharply reduced, then the air drums occurs in the ABS pump. In this case, air removal must be performed on a service station using a special device. When replacing any brake hose, air from the system also need to be removed per service station. While it is not done, it is impossible to use the car.
