12.10.1. Pumping – the main method (two persons)

PERFORMANCE ORDER
1. Remove a dustproof cap from the union of pumping of the wheel cylinder, clear it and put on it the pure transparent hose which other end lower in the capacity which has been partially filled with brake liquid. The capacity should be at least on 300 mm above the pumping union. Thanks to it air hit in the cylinder through a carving of the union of pumping is prevented.
2. Sharply press a pedal of a brake of 3-5 times with an interval of 2-3 seconds, unscrew on a half of turn the pumping union at the pressed pedal.
3. Continuing to press a pedal, force out the liquid which was in system together with air through a hose in capacity.
4. After the pedal will reach extreme forward situation and the liquid effluence through a hose will stop, screw the pumping union home.
5. Repeat these operations, the air outlet from a hose will not stop yet.
6. Holding a pedal in the pressed situation, screw up the pumping union against the stop and remove a hose.
7. Wipe the union of pumping and establish a protective cap.
8. Repeat these operations for other wheels.

Prevention

At air removal constantly watch availability of brake liquid in a tank, without allowing an exposure of its bottom as thus air again will get to system.


9. At absence the pedal should pass about a half of the course in system of brakes of air. To exclude influence of the vacuum amplifier of brakes on pumping of brakes, removal of air make at the idle engine.
