Bleeding Brake System With Brake Filler and Bleeder Unit VAS 5234, Vehicles With ABS Mark 60

Bleeding brake system with brake filler and bleeder unit VAS 5234, vehicles with ABS Mark 60





The bleeding of the brake system is described for brake filler and bleeder unit VAS 5234

Special points regarding vehicles with ABS/EDL, ABS/EDL/ASR and ABS/EDL/ASR/ESP
When at least one chamber in the brake fluid reservoir is completely empty (e.g. leaks in braking system) the hydraulic unit must be bled with scan tool VAG 1551 in function "basic setting".

Then the hydraulic unit must be bled with scan tool VAG 1551 in function "basic setting".

Introduction of basic setting
Connect VAS 5051 and select functions.
- Then bleed brake system.

Special points regarding vehicles with ABS/EDL/ASR/ESP
After bleeding the brake system perform a zero compensation of the brake pressure sender -1- -G201-.
Connect VAS 5051 and select functions.
Once the bleeding sequence is completed. Carry out a test drive and perform at least one ABS application when doing this.

WARNING! Make sure that a filling pressure of 1 bar (14.5 psi) is not exceeded, when filling brake fluid using brake filler and bleeder unit VAS 5234.





The brake fluid pressure must be reduced to 1 bar (14.5 psi) on brake filler and bleeder unit VAS 5234.

Note:
^ Use new brake fluid with part No. B 000 700 A. (Enter container size index for decimal point after the A).
^ Brake fluid is poisonous. Brake fluid must not come into contact with paintwork as it is very corrosive.
^ Brake fluid is hygroscopic, which means it absorbs moisture from the ambient air and should always be stored in air tight containers.
^ Rinse off brake fluid spillages, by using plenty of water.

Special tools and equipment





^ VAS 5234 Brake filler and bleeder unit

- Connect brake filler and bleeder unit VAS 5234.
- Open bleeder screws in the prescribed sequence and bleed brake caliper/wheel cylinder.

Bleeding sequence
1- Left front brake caliper
2- Right front brake caliper
3- Left rear wheel cylinder/brake caliper
4- Right rear wheel cylinder/brake caliper

- With hose still connected, leave the respective bleeder screw open until brake fluid is free from air bubbles out of the bleeder screw.
A test drive must be carried out after bleeding brakes. When doing this an ABS application must be performed at least once!

Changing brake fluid
Pre-bleed the brake system when at least one chamber in the brake fluid reservoir is completely empty (e.g. leaks in braking system).

Pre-bleeding sequence
1- Bleed left front and right front brake calipers simultaneously
2- Bleed left rear and right rear brake calipers simultaneously
- With hose still connected, leave the respective bleeder screw open until brake fluid is free from air bubbles flows out of the bleeder screw.
