Rear Pads: Installation

  1. Use Resetting Tool (VW 3272) to seat caliper piston fully into cylinder bore. See Fig 1 . Before pressing the piston back, draw off brake fluid from the reservoir with a bleeder bottle. Otherwise if reservoir has been topped off, fluid will overflow and cause damage to finish. Seat piston by turning special tool until piston is bottomed out in bore.

  2. Install brake pads, note positioning of pad to caliper (tab on pad must fit into groove on caliper piston). If reusing old pads, ensure that pads are installed in original positions or braking may be uneven. Position caliper.
  3. Install NEW caliper mounting bolts. With engine off, depress brake pedal several times to allow pads to move into operating position. Top off master cylinder reservoir as necessary. Adjust parking brake as necessary. See PARKING BRAKE  under ADJUSTMENTS.
