What brake fluid in Chevrolet Lacetti. Chevrolet Lacetti brake fluid. What are the liquids of Lacetti

the main / Engine

Many owners of Chevrolet Lacetti have come across such a phenomenon as the falling level of brake fluid. The occurrence of such an effect may be associated with wear. brake shoes or other malfunctions in this system. After eliminating trouble, it will be a question - what liquid is to attach. In this article, let's try to disassemble all the nuances and subtleties.

The process of topping the brake fluid into the car.

As you know, the Chevrolet brand belongs to the American Corporation General Motors, even the car and collect in Korea, and, accordingly, all the standards apply to this particular company.

Liquids also refer to standardization item, and therefore, in Chevrolet, the lacetti is poured from the plant only the recommended and certified lubricants.

According to the service documentation, which was able to get from the manufacturer's manufactory manuals in Lacetti, at the plant when assembling, is poured dot-4 brake fluid .
This is original lubricant General Motors, which has an article - 93160363 .
The average cost of one liter of such a fluid is 1200 rubles.

GENERAL MOTORS brake fluid.

There is also a GM fluid with marking 1942421, which was intended for opel carsBut in 2005-2006 he fouled in Chevrolet Lacetti. This lubricant and GM 93160363 have identical characteristics, composition and properties. According to the manufacturer's clarification, two different lubrication marking can be mixed with each other without any consequences. They are considered interchangeable.

Therefore, if the motorist is confident that vehicle There was no complete replacement of the brake fluid, it can be boldly to fill GM 93160363. or GM 1942421..

After a full fluid change

As practice shows, in Russia spend full replacement The brake fluid is not on GM 93160363 or GM 1942421, but on the usual ROSDOTH-4. This is due to the fact that the brand russian manufacturer Quite cheaper than an American counterpart.

There is such a radical replacement, as a rule, on the third maintenance vehicle.

Brake fluid production of ROSDOTOT-4.

Therefore, if you want to add brake fluid It is necessary to pay attention to mileage and other factors. It is advisable to have a printout previous repairs And what is indicated which fluid is poured.

Difference of the original brake fluid and domestic counterpart

The original brake fluid is not so dark as its domestic analog.

As a rule, in order not to consume, the brake fluids GM 93160363 / GM 1942421 and ROSDOTOT-4 have characteristic differences. The American brand is characterized by color, or rather a tint.

GM brake fluid has a bluish shade, unlike the domestic counterpart, which are darker, with a brown tint.

Thus, the motorist can unscrew the tank with the brake fluid and understand what is actually filled into the car.

conclusions

To top up the brake fluid without replacing in Chevrolet Lacetti can, only at the same time it is necessary to know which lubricant was flooded. As practice shows, fluids GM are flooded 93160363 / GM 1942421 or ROSDOTH-4 . They can be discharged in color and viscosity.

Attention! When operating a car with a trailer and frequent trips to mountain roads Brake fluid must be replaced every 15,000 km of mileage.

Work performed on the viewing ditch or overpass.

Pump out old liquid From the tank with a syringe or rubber pear.

Fill in a tank new liquid.

It is necessary to pump the hydraulic drivers of the brake system and the clutch until the new liquid (brighter than the old one) fails to leave the bumps of pumping of all workers cylinders.

Replacing the brake hydraulic fluid

Pumping to replace fluid disabled Engine First on one contour, and then on the other in the following sequence:

brake mechanism of the right rear wheel
brake mechanism left front wheel
brake mechanism of the left rear wheel
brake mechanism of the right front wheel.

Before pumping, check the level of working fluid in the tank of the brake hydraulic drivers and clutch. If necessary, plunge the liquid.

Pumping brakes spend with an assistant.

Cleaning from mud shocking the brake mechanism of the right rear wheel.

Remove the protective cap from the fitting.

The assistant should vigorously press the brake pedal until it stops 1-2 times and keep it pressed.

The keyproof key "on 10" turns out the compartment fitting by 1/2-3 / 4 turns.

At the same time, liquid will flow out of the hose, and the brake pedal should be harvested until it stops.

As soon as the liquid stops flowing out of the hose, wrap the fitting, and only after that the assistant can let go of the pedal.

We repeat this operation until a new brake fluid comes from the fitting (brighter than old).

We remove the hose, wipe the bleeding fitting and put on it a protective cap.

Remove the protective cap from the bleeding mechanism of the left front wheel.

We wear a hose on the fitting, and its free end is immersed in the container, partially filled with working fluid.

Pouring, as described above, the brake mechanism of the left front wheel, turning the pumping fitting with the "10" key.

Similarly, pump the brake mechanisms of another contour.

When pumping, you need to follow the level of fluid in the tank and add liquid.

Replacing the fluid of hydraulic clutch

We carry out work with the assistant.

Before pumping, check the fluid level in the tank on the main brake cylinder. If necessary, felt liquid.

Remove the protective cap from the pumping fitting.

The key "On 10" weakened the tightening of the pumping fitting, holding the tube adapter with the "19" key.

We put on a transparent hose on the fitting, the other end of the hose is lowered into the container, partially filled with the working fluid, so that the free end of the hose is immersed in the liquid.

Capacity is desirable to set below the level of the fitting.

The assistant presses several times on the clutch pedal and holds it down.

When the clutch pedal is pressed, we turn into 1/2-3 / 4 turnover of the pumping fitting. In this case, the liquid is displaced into the container. Holding the pedal pressed, wrap the fitting and repeat this operation until the new brake fluid go out of the fitting (brighter than old).

Remove the hose and put on the fitting the protective cap.

After pumping the hydraulic drives of the brakes and the clutch, bring the fluid level in the tank to normal.

There is an even simpler version of the brake fluid replacement. This method does not require the presence of an assistant. In this method, some brake fluid supply is desirable (at least 1 liter).

We establish a car on the viewing ditch or the overpass and provide a free passage between the tank with the brake fluid in the pumproom space and brake cylinders of all wheels.

Pump a rubber pear or a syringe brake fluid from the tank. Take a new liquid to the upper edge. To accelerate the process (in order to produce liquid from all cylinders at once), it is desirable to choose four cuts of tubes that wear all cylinder pumps tightly. The free ends of the tubes are lowered into transparent bottles of a small container.

We turn out the fittings of all brake cylinders. We are convinced that the liquid flowed over all four tubes. Control the decrease in the liquid from the tank located on the brake cylinder, and immediately replenish the tank. We observe the rise of the level of liquid in bottles located near the wheel brake cylinders.

It is necessary to move several times from the position of the observation of the fluid from the brake cylinder fittings to the position when you can check and replenish the fluid level in the tank located on the brake cylinder to prevent the tank drainage.

Usually the fastest level increases in the bottle, which is lowered the hose coming from the front left wheel brake cylinder. As soon as in the bottle of the front left wheel, about 200 ml of fluid will turn out, we wrap and tighten the fitting of this cylinder. Next, we wait for the same result at the front right wheel cylinder and also wrapping his pumping fitting. You can complete the process after a 200-250 ml of liquid will be released through the fitting of each rear wheel.

We are convinced of a hermetic tightening of all fittings. Wear protective caps. We specify the level of fluid in the tank of the main brake cylinder.

Replacing the Lacetti brake fluid is a very necessary procedure. Moreover, the brake fluid replacement does not independently represent a special difficulty.

It is also worth noting that hydraulic drive The brakes and the hydraulic clutch drive on the Chevrolet lacetta feed from one tank, so when replacing the fluid in the hydraulic drive of the brakes, it is advisable to change the brake fluid and in the clutch shutdown.

Working brake system Chevrolet lateti dual circuit, diagonal. Each of the brake contours of Lacetti includes brake mechanisms of two wheels: one front and one rear, located on a car diagonally. At the failure of one of the contours, the second circuit, albeit with less efficiency, but will ensure the stop of the car.

Why change brake fluid

The brake fluid is advised to change every 2-3 years, depending on the age of the car and the state of the brake system as a whole. Those. The older car - the more often it is desirable to change the brake fluid. Also, if the liquid changed the color prematurely, then it must be changed, without waiting for a certain period.

The most important answer to the question is why to change the brake fluid is that the brake fluid is hygroscopic. Simply put, she absorbs moisture. And it is very, very bad for two main reasons.

First, it leads to increased corrosion of the elements of the brake system.

Secondly, the boiling point of the brake fluid is sharply reduced. On containers with brake fluid, you can read the following:

It can be seen that only one year the boiling point is reduced by 30-40%!

I think further arguments in favor of regular replacement of the brake fluid does not make sense.

Step-by-step replacement of brake fluid lacetti

To work, you will need an assistant, the "10 mm" cape key, as well as:

Rubber pear or syringe;
- transparent vinyl tube with an inner diameter of 4-5 mm, comes from a dropper;
- the tank for the drain of the waste brake fluid;
- Fresh brake fluid DOT4. In the brake system lacetti, 0.5 liters of fluid is flooded. But you buy at least 1 liter to replace;
- looking Yama or estacade (preferably).

1. We unscrew the tank cover of the main brake cylinder Chevrolet Lacetti and select the whole brake fluid with a syringe or rubber pear.

2. Pour fresh liquid to the top edge into the tank.

Important:
To avoid air penetration into the hydraulic drive of the brake system during the replacement of the brake fluid, ensure that its level in the tank has fallen below the MIN mark.

3. In the rear right wheel, we find a jacket fitting, we clean it from dirt and put a transparent tube on it. It is advisable to apply WD-40 on it, and then these fitters have the properties of "accuming". The second end of the tube is lowered into the tank for the waste fluid.

4. The assistant slowly presses the brake pedal (approximately 5 clicks with an interval of 1-2 seconds) and holds the pedal pressed. At this moment, unscrew the fitting on 3/4 turns. A liquid should be distilled from the fitting on the tube until the brake pedal does not reach the floor. After that, twist the fitting. The assistant should not let go of the pedal until you tighten the fitting!

Note! It happens that when unscrewing the fitting, the liquid does not go through the tube. Especially if you have crushed the brake fluid replacement period. This means that the inner hole of the fitting was hampered. It is necessary to unscrew the fitting completely and clean the hole. Then wrap the fitting into place and continue pumping the brake system.

We do this sequence again while the tube does not start out the fresh liquid (you define it in color).

5. Then this procedure is carried out in the sequence - left rear, right front, left front. And carefully follow the level of the brake fluid!

I will say a few words about the sequence of recalculation of calipers. Who pumps on the diagonal, who is from the long-distance neighbor ... I think there is no particular difference. I tried it and so. The result is always the same. Therefore, I do as convenient for me and as you used in the old way - the right rear, left rear, right front, left front.

Therefore, decide in what sequence to do it.

Here is pumping the last caliper

After from all the fittings, fresh and clean brake fluid will be outlined, we add it to the level in the tank, close the tank cover and make a trial trip, paying attention to the work of the brakes. After the trip, make a level control in the tank.

Possible problems with calipers and solutions

That's all. Take care of yourself and good luck on the roads!

Many owners of Chevrolet car owners Chevrolet Lacetti or Cruz are interested in the question - what brake fluid braking GM 93160363 or 1942421 should be poured into the braking system?

Currently, in order to attach the brake fluid, it is not at all necessary to contact the dealer. Instead, get in the store or in a reliable supplier brake fluid at the part number. Remember marking:

93160363 - GM brake fluid marking
1942421 - Opel brake fluid marking

The brake fluid of both species is absolutely the same, but is produced for different conements by Adam Opel AG, Russelsheim Germany. Liquid for the brake system of the Chevrolet Car Chevrolet Lacetti or Cruz has a class DOT-4, light orange color and packaged into plastic hermetic container white color 0.25 / 0.5 / 1 liter. Canister has a transparent scale for which the color and amount of fluid can be determined in the canister. The stopper breakdown, which allows you to control whether the canister opened earlier. On the front side is marked: month and year denoting the latter opportunity to open and use this canister with brake fluid.

Many car enthusiasts are a bit experienced due to the labeling of the canister. Remember again - the brake fluid with the marking 93160363 is absolutely identical to the marking of 1942421. They can be interchanged and mixed together!

The average price canister 0.5 liter of brake fluid GM 93160363 or 1942421 in retail from 410 to 523 rubles. Its value in the online store (for example, Emeh) from 280-300 rubles with a period of delivery of 2 days. Nearest recommended analogues: FEBI 21754, SEIKEN BF405L, SWAG 10921754 and AD LFS1. Brake fluid domestic producers It is impossible to pour.

Hydraulic driving brake system Chevrolet Lacetti. It has two contours, including with the ABS system. Each of these contours of the car provides the operation of braking wheels of two mechanisms located on the machine in diagonal.

The car also has one tank that is responsible for the supply of the working fluid, both for the clutch system and for the vehicle. The correct performance of the brakes is supported not only to the fact that it is necessary to change the pads, but also to replace the brake fluid in time, according to the Lacetti Regulation. How to do it - see pictures.

According to the application for use operational liquids For Chevrolet Lacetti into the brake hydraulic system and clutch system should be poured 0.5 liters Brake fluid.

The manufacturer allows brake fluid that meets the requirements of the specification FMVSS116 and DOT4 Standard.

In some manuals, the use of Dot5 on the Chevrolet Lacetti car. It should be mentioned that in the same instructions it is indicated which the TJ should be used, the name of which is indicated on the tank of the main brake cylinder (GTC). Secondly, the DOT5 brake fluid is not compatible with the DOT3, nor from Dot4 +, nor from Dot4 and besides in cars having aBS system not used.

The original GENERAL MOTORS brake fluid has an article 93160363. A similar replacement will be brake fluid "Brake Fluid" from Opel, catalogue number - 1942421, manufactured by Gmotors for Opel cars. Price of this working fluid 450 rubles.

Also available is a wide range of TJ from other manufacturers of Fenox "Sbrake" SBF4005, Miles "Brake Fluid" EBF455, Hella-Pagid "Brake Fluid" 8DF355360011, Miles "Brake Fluid" EBF910. The price of liquid data varies from 100 to 200 rubles.

Prices are relevant for the fall of 2017 for Moscow and the region.

How to change the brake fluid on Chevrolet Lacetti

To do this, you will have to pump out old tank liquid, pour fresh, create pressure in the system (by moving the pedal or special device), put on the fitting the hose (one end of which will be in a transparent bottle with liquid), unscrew the fitting of pumping on the wheel caliper, wait until it goes Fresh brake fluid without air. It is very important to observe the pumping scheme.

The air from the system is removed with a muffled motor, from the beginning from one contour, and then from the other to which the sequence of pumping of the brakes: the right rear wheel; left front wheel; left rear wheel; right front wheel.

Instructions for replacement DIY DIY:

We unscrew the cover of the GTC reservoir.
With the help of a syringe, pump the working fluid from the tank.
We lay a new TJ to the bottom crown in the tank neck.
It is important to prevent the penetration of air into the hydraulic system of the car. To do this, it is necessary to ensure that its level in the tank fell below the MIN mark.
Pumping the brakes must be carried out with the subband. Sulling out of the pollution of the brake cylinder of the wheel and remove the protective cap.
Using the key "On 10" weakening the tightening of the pumping fitting.
We put on the vinyl hose for one end, and the other omit in the bottle, half filled with brake fluid.
The subband must squeeze the pedal 4-5 times, having rolling the TJ and keep it in the lower position.
We continue to unscrew the socket on the ½-¾ turnover. At the same time, old TJ and bubbles of air should go out of the end of the tube, and in the meantime the pedal lives until it stops.
As soon as the TJ stops flowing, wrapping the fitting and let go of the pedal.
We carry out the above actions as long as the hose does not fly a new brazersushka. At the same time, the pedal move should not exceed half the distance to the floor.
We carry out similar actions on another wheel of the same contour (according to the scheme).
In the same way, we pump the brake mechanisms of wheels of another contour (according to the scheme).
