Brake Bleeding: Service and Repair

Brake System Bleeding

Procedure covers bleeding of the brake system using the brake charger/bleeder unit (VAS 5234) or ( V.A.G 1869).

‹› Bleeding the braking system on vehicles with Anti-lock Brake System (ABS) is carried out the same as for vehicles with conventional braking

systems. 

‹› Only use new brake fluid conforming to US-Norm FMVSS 116 DOT 4.

‹› Genuine VW/Audi brake fluid conforms to this specification.

‹› Brake fluid is poisonous. Due to its caustic nature, it must also never be brought into contact with paint.

‹› Brake fluid is hygroscopic, meaning that it absorbs moisture from the surrounding air, and must therefore be stored in air tight containers.

‹› Rinse off any spilled brake fluid using plenty of water.

There must be a positive pressure of 2 bar to bleed the hydraulic unit.

Procedure

Special tools, testers and auxiliary items required

‹› Brake charger/bleeder unit (VAS 5234)

Commercially Available Tool

‹› On vehicles with Electronic Differential Lock (EDL), EDL/Anti-Slip Regulation (ASR) or EDL/ASR/Electronic Stabilization Program (ESP), the

brake system must be pre-bled when a chamber in the brake fluid reservoir is completely empty. This will happen if there are leaks in the brake
system.

Pre-Bleeding

-

Connect the (VAS 5234) or (V.A.G 1869 ).

Bleeding sequence:

1 - Bleed the left front and right front brake calipers simultaneously 

2 - Bleed the left rear and right rear brake caliper together simultaneously 

-

With the bleeder bottle hoses attached, leave the bleeder valves open long enough that brake fluid exits without bubbles.

-

Then, the brake system must be bled normally
