                     ABS Brake Pump Bleeding

ABS Brake Pump Bleeding
Updated  13 Feb. 2012

Ross-Tech is not responsible for any damage or problems that may result from following these instructions. They are to be used at your own risk. These instructions apply to many older VW/Audi models but may not work with many newer ones. As always, you should refer to a Factory Repair Manual for your vehicle! Also check the Ross-Tech Wiki to see if there are vehicle-specific instructions that you should use instead.

This procedure details how to bleed the ABS pump when replacing brake fluid. This procedure is NOT necessary unless your ABS pump has gone completely dry. For normal brake work including fluid replacement, hose replacement, pad replacement, etc. this procedure is NOT necessary. Also, this procedure does not take the place of good ol' fashioned brake bleeding with one person operating the pedal while the other person opens the bleeder valves one by one and collects the discharged fluid.

There are certain test conditions that must be met before doing this procedure:

  • Vehicle must on a lift or safe jack stands with no wheels touching the ground

  • Ignition should be in the "On" position


Procedure for Bleeding the ABS Brake Pump in many older VW Golf, GTI, Jetta, and Audi TT with Mk20 or Mk60:

[Select]
[03 - ABS Brakes]
[Basic Settings - 04]
Group 001 (may be group 002 in Mk3 VW Golf/Jetta)
[Go!]

This will trigger the ABS pump to turn on for about 10 seconds. You should hear the fairly loud pump clicking during this time.

Click the [Done, Go Back] button and you're all set.
