Brake Caliper Piston, Removing and Installing

Special tools and workshop equipment required

  • Trim Removal Wedge -3409-

Removing

  • Rotate the spindle in the direction of -arrow- with an 8 mm socket.

The pressure nut presses the piston out of the brake caliper.

  • Remove the piston with the protective boot from the brake caliper.

The outer sealing lip thereby slips into the groove on the piston.

Brake Caliper, Pre-Bleeding

  • Open the bleeder valve -arrow A- and using a commercially available bleeder bottle, fill with brake fluid until brake fluid flows out of the threaded hole (brake hose connection) -arrow B- without any bubbles. Close the bleeder valve.

Position the brake caliper as shown during the pre-bleed procedure.

Pressure Leak Test

Special tools and workshop equipment required

  • Brake Pressure Gauge -VAG1310A-
  • Brake Pressure Gauge - Adapter M10 -VAG1310/6-

Test Requirement

Brake system (hydraulic unit, brake hoses, brake lines and brake calipers) operating properly and free of leaks.

  • Remove the bleeder valve at one of the front brake calipers. Connect the Brake Pressure Gauge -VAG1310A- and bleed.
  • Apply pressure to the brake pedal until the pressure gauge indicates a pressure of 50 bar (725 psi). The pressure must not drop more than 4 bar (58 psi) during the test period of 45 seconds. Replace the brake master cylinder if the pressure decrease is too high.
