12.10.2. Pumping – set use with the unidirectional valve


The set consists of a tube with the unidirectional valve established on it which excludes possibility of return to brake system of remote brake liquid with air vials. On some sets the transparent container in which air vials in brake liquid are well looked through is established.

1. Remove a dustproof cap from the union of pumping of the wheel cylinder, clear it and put on it a hose from a set.
2. Unscrew on a turn half the pumping union.
3. Smoothly press a brake pedal against the stop and slowly release it in a starting position.
4. Repeat this operation until from the union of pumping there will be no brake liquid without air vials.
5. Tighten the pumping union against the stop, remove from it a tube and dress a dustproof cap.


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.
