3.15. Problems with brakes
The brake system of your car is supplied by the vacuum amplifier, anti-blocking system (ABS) and is quite effective. Decrease in efficiency of braking, car drift when braking should become a signal for urgent check of a brake.
Regularly check level of brake liquid in a tank of the main brake cylinder. Level of brake liquid should be about «MAX» label on the tank case.
Falling of level of liquid testifies or to leakage of brake liquid from system, or about excessive wear of brake shoes. If on an instrument guard the lamp signaling about low level of brake liquid lit up, do not hurry up at once to add it, at first check thickness of overlays of brake shoes: can be, came to replace time blocks?
Producers of the car recommend to replace all brake liquid in system through 40 000 km of run or 2 years (that will come earlier).
Some drivers scorn this opinion as liquid in a tank seems to them rather pure, and it is absolutely vain. The matter is that brake liquid is very hygroscopic (absorbs moisture from air), and this moisture over time not only destroys surfaces of brake cylinders, pipelines and, as a result, leads to premature failure of knots of brake system, but also essentially reduces temperature of boiling of brake liquid. The normal temperature of boiling of brake liquids of the class DOT-4 makes 210–260 °C. At frequent intensive braking disk brakes strongly heat up, at the big content of water brake liquid can boil that, as a rule, leads to refusal of brakes.
In order that in the future not to subject itself to contingencies for repair not only brake system, but also all car, it is better to replace in due time liquid in brake system.
We recommend to replace brake liquid in 1 year.
