3.17. Problems with brakes

The brake system of your car is supplied by the vacuum amplifier and is effective enough. Decrease in efficiency of braking, car drift at braking should signal become urgent to check up a brake.

THE PREVENTION
Regularly check level of a brake liquid in a tank of the main brake cylinder. Level of a brake liquid should be between labels «MAX» and «MIN» on a tank wall (approximately at level of a socket of a tank).

Falling of level of a liquid testifies or to leak of a brake liquid from system, or about excessive deterioration brake колодок. If on an instrument guard the lamp signalling about low level of a brake liquid has lighted up, do not hurry up at once to add it, in the beginning check up a thickness of overlays brake колодок: can be, has come to replace time pad?
Manufacturers of the car recommend to replace through the certain period all brake liquid in system. Some drivers scorn this opinion as the liquid in a tank seems to them enough pure, and it is absolutely vain. The matter is that the brake liquid very much гигроскопична – it absorbs a moisture from air, and this moisture not only destroys in due course surfaces of brake cylinders, pipelines and, as consequence, leads to premature failure of knots of brake system, but also essentially reduces temperature of boiling of a brake liquid. Normal temperature of boiling of a brake liquid "Neva" – 190 °С, "Tom'" – 210 °С, "Dew" – 260 °С. At frequent intensive braking disk brakes of forward wheels very strongly heat up and at the big maintenance of water the brake liquid can boil that, as a rule, leads to refusal of brakes.

       GOOD ADVICE
Not to subject itself in the future to contingencies for repair not only brake system, but also all car, better in due time to replace a liquid in brake system.

Prorolling of brake system
If the brake pedal became "soft", and by several consecutive pressing becomes firmer", it testifies to air presence in a hydraulic brake drive.
For removal of air from system it is necessary to pump over brakes. Procedure of prorolling of brakes simple enough, but is more convenient to spend her with the assistant. More in detail this work is described in section 8 «Brake system».

Check of brake system
1. Unsatisfactory work of the vacuum amplifier can be the reason of loss of efficiency of braking. For its express check press some times a brake pedal at the idle engine to remove depression in the amplifier, and then, keeping a pedal, start up the engine. If after start-up of the engine the pedal has a little fallen, the vacuum amplifier is serviceable.
2. If the pedal remained motionless, check up an integrity and reliability of fastening of a hose to the return valve of the vacuum amplifier...
3.... And to an inlet pipe of the engine. A faulty hose replace or repair. If the hose is serviceable, replacement of the vacuum amplifier (section 8 «Brake system» see) is required.
If braking is accompanied биениями and a pulsation of a brake pedal, it is necessary to check up first of all a condition of forward disk brake mechanisms.
Having established the car on a jack, remove a forward wheel and check up mobility brake колодок. For this purpose through a window in скобе a screw-driver try to move pad in support nests. If pad it is impossible to take away from a brake disk, it means that pad have lost mobility in nests of a support or "has jammed" the piston in the brake cylinder.

       THE PREVENTION
Jamming of the piston of the brake cylinder leads constant притормаживанию a corresponding wheel at the released pedal and to car drift at braking.

4. Remove скобу (section 8 «Brake system» see, «Replacement brake колодок the forward brake mechanism») and check up mobility колодок. If they move with difficulty, clear face surfaces of the bases колодок and nests in a support of a dirt and a rust, having provided absolutely free moving колодок. Simultaneously check up a thickness of overlays колодок. If it less than 3 mm, replace pad.
5. Examine a brake disk. The thickness of a brake disk should be not less than 9,5 mm. The disk surface should be equal and smooth from both parties. If the surface of a disk in places is covered by a rust that usually happens after long parking of the car to not dried brakes, try to smooth out a working surface small наждачным a cloth. If this procedure has not helped, it is necessary to give disks to polishing or to replace new.

       GOOD ADVICE
Lay brake put in action a cable connecting the lever of a lay brake and the mechanism of management brake колодками of back brakes. Many drivers try to use as seldom as possible a lay brake to prolong his life, and achieve opposite result. If you do not use a lay brake, in cable covers the dirt and a moisture stand, the cable acquires a rust, ceases to move and breaks. Therefore use a lay brake in necessary cases, but do not forget to regulate its drive from time to time. Process of adjustment of a lay brake is in detail described in section 8 «Brake system»
