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
Bleeding sequence ABS Mark 60
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 V.A.G 1551 in function "basic setting".
Pre-bleeding sequence ABS Mark 60
Then the hydraulic unit must be bled with scan tool V.A.G 1551 in function "basic setting".

Introduction of basic setting
Refer to Brake System On Board Diagnostic (OBD), Mark 60 Initiating basic settings. Testing and Inspection

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 -
Refer to On Board Diagnostic (OBD); Performing self-diagnosis; Initiating basic settings. Testing and Inspection
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 Operating instructions 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 hydroscopic, 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





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

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!

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 front brake calipers simultaneously
- With hose still connected, leave the respective bleed screw open until brake fluid is free from air bubbles flows out of the bleed screw.

Bleeding brake system without brake filling and bleeding appliance
- Build-up brake pressure in brake system by pumping the brake pedal.
- Attach bleeder bottle hose and open bleed screw.
- With brake pedal held down, close bleed screw.
- Repeat operation until no air is present.
Bleeding sequence ABS Mark 60, refer to Brake Bleeding; Service and Repair.

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).
