| 1. Remove a dustproof cap from the union of pumping of the wheel cylinder, clear it and dress on it a pure transparent hose which other end lower in the capacity which is partially filled with brake fluid. Capacity has to be at least 300 mm above the pumping union. Thanks to it hit of air in the cylinder through a pumping union carving is prevented. |
| 2. Sharply press a pedal of a brake of 3-5 times with an interval 2–3 seconds, unscrew half way the pumping union at the pressed pedal. |
| 3. Continuing to press a pedal, force out the liquid which is in system together with air through a hose in capacity. |
| 4. After the pedal reaches extreme forward situation and the liquid effluence through a hose will stop, screw the pumping union to the full. |
| 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
During removal of air constantly you monitor availability of brake fluid in a tank, without allowing an exposure of its bottom as at the same time air will get to system again.
|
| 9. At absence the pedal has to 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, you make removal of air at the idle engine. |
