Installing Front Brake Pads - PCCB Brakes

→ Only use the type-specific brake pads listed in the Porsche Parts Catalogue.

→ Replace the brake pads when the brake pad wear indicator light comes on, but no later than when there is a residual pad thickness of 2 mm on each axle.

→ Replace the brake discs on each axle as soon as the brake pad wear limit is reached.

→ Fit new expanding spring, new retaining pin and securing clip on the brake calliper.

• Make sure the retaining pin is inserted at the correct position. The side levelling surfaces prevent the retaining pin from twisting in the brake calliper.
• Do not grease the back of the disc brake pad.
• Check disc brakes for wear. For details of wear limits, see → 4600TW TECHNICAL DATA/BRAKE WEAR LIMIT .
• The core of the warning contact wire must not be left exposed. Worn insulation is not important.
• Use a new repair kit.

1. Before installing the brake pads, check the amount of wear on the brake discs. → 4600TW TECHNICAL DATA/BRAKE WEAR LIMIT .
2. If necessary, push the brake pistons back into their original position using the brake piston resetting fixture 9472  (for 6-piston brake calliper).

3. Fit new disc brake pads.
   1. 3.1. If you are using Pagid P40-2  brake pads, insert new damping plates into the pistons.

      The protective film on the damping plates must be removed before installation. When fitting the damping plates on the small pistons, position the cut-out on the damping plate at the brake-pad guide pins to prevent the damping plate from becoming deformed.

4. Install expanding spring. Centre the retaining pin in the bore using the M8 auxiliary screw. To do this, push the retaining pin back with the auxiliary screw and then push the retaining pin through. Remove auxiliary screw and tighten new fastening screw at the retaining pin to 30 Nm (22 ftlb.).
