14.2. Pumping of hydraulic system of the drive of brakes
Hydraulic doghouses of the brake system
1 – vacuum amplifier of brakes; 2 – main brake cylinder; 3 – central valve; 4 – compensation tank; 5 – sensor of level of brake fluid; 6 – accumulator of low pressure; |
7 – pump block; 8 – electric motor; 9 – inlet valve (NO); 10 – inlet valve (NO); 11 – final valve (NC); 12 – final valve (NC) |
Element hydraulic doghouse of the anti-blocking brake system
1 – ABS block; 2 – the damping camera; 3 – electric motor; 4 – compensation tank; 5 – main brake cylinder; 6 – vacuum amplifier of brakes; 7 – pressure accumulator; |
8 – brake pedal; 9 – position of primary piston; 10 – central valve; 11 – inlet valve; 12 – sensor of frequency of rotation of a wheel; 13 – support; 14 – final valve |
Any hydraulic system works normally if air is removed from it.
PERFORMANCE ORDER |
1. Lift the car and fix on support. |
Prevention
Liquid in a popolnitelny tank of the brake system has to be supported at the level of 3/4 or is higher in the course of pumping.
During removal of air add only pure liquid recommended by the manufacturer
|
2. You carry out removal of air in the following order: – right forward wheel; – left forward wheel; – right back wheel; – left back wheel. |
3. Turn off a cover from the union of pumping and attach to it a hose. |
 |
4. Arrange other end of a hose in glass capacity, sufficient volume. |
5. Slowly press a brake pedal several times. |
6. At the pressed brake pedal a key of OK130 430 019 weaken the union of pumping and let out the air from hydraulic system. |
7. Tighten the union of pumping and release a brake pedal.
Inhaling moment: 5,9–8,8 N • m |
8. Repeat operations 5-7 until there is a brake fluid without vials of air. |
9. Screw a cover on the pumping union. |
10. Check correctness of work of a brake. |
11. Check lack of leak of brake fluid. |
12. Add brake fluid in a popolnitelny tank of the brake system. |
