Brake Pads, Removing and Installing

Special tools and workshop equipment required

  • Vehicle Diagnostic Tester
  • Diagnostic Cable -VAS5051/1- or Diagnostic Cable -VAS5051/3-
  • Torque Wrench 1331 5-50Nm -VAG1331-
  • Piston Resetting Tool -T10145-

Removing

When removing, mark the brake pads that will be used again. Install in the same position, otherwise the braking effect will be uneven.

Note

Do not disconnect the connectors from the parking brake motors.

  • Parking brake not actuated.
  • Remove the wheels.

The pistons of the parking brake must be driven back using the Vehicle Diagnostic Tester.

Before pressing the piston back, extract the brake fluid from brake fluid reservoir. Otherwise the brake fluid will overflow and cause damage, especially if the brake fluid was added intermittently.

  • Connect the -Vehicle Diagnostic Tester- and select the function.
  • Select the electro-mechanical parking brake and the function "Moving piston of parking brake motor out and in".
  • Drive the pistons back using the Vehicle Diagnostic Tester.
  • Then, unscrew the bolts from the brake caliper, while counterholding the guide pins.
  • Remove the brake caliper downward from the brake carrier.

Note

Resetting the piston with Vehicle Diagnostic Tester is often not sufficient but necessary! The thrust nut in the piston is a sliding mount so the piston can only be pressed and cannot be pulled back. Only the spindle with the thrust nut is moved back.

Caution

The piston must first be reset with the Vehicle Diagnostic Tester.

  • Now press the piston all the way back with the Piston Resetting Tool -T10145-.
  • Secure the brake caliper with wire so the weight of caliper does not hang from or damage the brake line.
