11.12. Pumping of brake system

GENERAL INFORMATION

Effective work of any hydraulic system is possible only after removal from it all air. Process of removal of air of brake system is called as pumping. When pumping use only new, pure brake liquid. Before the beginning of pumping fill a tank with brake liquid above a mark the MOVE and watch, that level of brake liquid did not fall below this mark.

Pumping order

Pumping of brake system on models till 1998 of release with the ABS 3-channel system is necessary for carrying out in the following order:

  – brake of the left forward wheel;
  – brake of the right forward wheel;
  – brake of the left back wheel;
  – brake of the right back wheel.

Pumping of brake system on models since 1998 of release with the ABS 4-channel system is necessary for carrying out in the following order:

  – brake of the left back wheel;
  – brake of the right forward wheel;
  – brake of the right back wheel;
  – brake of the left forward wheel.

Main method

For use of this method the assistant is required.
PERFORMANCE ORDER
1. Remove a plastic cap from the valve of production of air on a brake of the first wheel.
2. Put on the valve a rubber tube.
3. Lower the second end of a tube in the capacity filled with brake liquid.
4. Check, that level of brake liquid in a tank was higher than a mark of MIN and ask the assistant to squeeze out a brake pedal several times and to leave it pressed.
5. Turn off the pumping valve (approximately on one turn) and wait, while brake liquid will flow down. When the stream of liquid will stop, close the valve, ask the assistant to release slowly a pedal of a brake and check liquid level in a tank.
6. Repeat point 5 while in following brake liquid there will be no air vials.
7. Reliably tighten the pumping valve, lift the receiver and put on a cap.
8. Repeat operation of pumping on brakes of other wheels.

Pumping with set use with the unilateral valve

In a rubber tube of such set the unilateral valve preventing hit of air and old brake liquid back in brake system is established. The set also can include capacity for collecting old brake liquid.

Pumping with set use for pumping under pressure

PERFORMANCE ORDER
Having connected a set for pumping under pressure to a tank of brake liquid, for pumping of system it is rather simple to open pumping valves in turn for a slitiya of old brake liquid and production of air.

Check (all methods)

PERFORMANCE ORDER
On termination of pumping wash away the spilled brake liquid, reliably twirl valves of pumping and establish on them caps. Once again check level of brake liquid.
