12:12. Pumping of the brake system

The ordinary brake system (without ABS)
1. If air got to system through a tank or at removal of the main brake cylinder, then it is necessary to pump over brakes of all four wheels.
2. If the brake tube was disconnected only on a brake of one, it is necessary to pump over' only a brake of this wheel.
3. If the brake tube or a hose were disconnected in the place between the main cylinder and any of brakes, then it is necessary to pump over brakes of these wheels.
4. Remove depression from a servoamplifier, having pressed a brake pedal several times at the switched-off engine.
5. Fill in brake fluid in a tank.
6. Prepare new brake fluid, the pure capacity which is partially filled with brake fluid, a plastic tube and a wrench.
7. Since the left back wheel, turn off the final screw, then slightly twirl it.

11.8 When pumping brakes the hose has to be connected to the final screw and the second end is lowered in brake fluid - the coming-out air will create bubbles - make sure that all air is removed before passing to the following wheel
9.



8. Put on the end of a tube the screw and lower the second end in brake fluid (11.8).
9. Ask the assistant to press a brake pedal several times, then to squeeze out a pedal up to the end.
10. When the pedal is squeezed out, open the final screw and wait until brake fluid flows down. Close the screw.
11. Repeat this operation until vials of air cease leaves through a tube. Then tighten the final screw and pump over a brake of the right forward wheel, the right back wheel and the left forward wheel. You watch liquid level in a tank.
12. Do not use old brake fluid.
13. Fill a tank with brake fluid upon completion of pumping.
14.  Check work of brakes. The pedal has to be rigid when pressing and not (to sink {. If it is necessary, repeat pumping.
The brake system with ABS
Attention! For pumping of the brake system the engine has to work with ABS. Lift the car and install it on reliable support.

11:15 Observe a pumping order (the final screw No. belongs to a brake of the left back wheel, the N6 screw - to a brake of the right back wheel)
1. Delay valves
2. Hydraulic modulator



15. Start the engine. Execute the operations described in points 8 and 10 and pump over supports of brakes and valves of a delay. Observe an order of pumping (11.15).
16. Remove air from the valve of a delay the same as from supports of brakes (11.15).
17. Reliably twirl final screws of the valve.
18. Pump over the hydraulic modulator located near a back wall of a motive compartment (11.15).
19. Fill a tank with brake fluid upon completion of pumping.
