Installing Front Brake Pads - 6-Piston Fixed Calliper

→ 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.

Information 

• With the introduction of modified brake pads, the brake-piston damping plates (claw plates in the brake pistons) are no longer used.

• The modified brake pads have a damping plate (on the brake-pad mounting plate) -1-  . This damping plate -1- is covered with protective paper. Remove the protective paper completely before installing the brake pads.

Information 

• Make sure that 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. 
• The core of the warning contact wire must not be left exposed. It does not matter if the insulation is worn. 
• Use new mounting parts. 
• Remove some brake fluid from the brake fluid reservoir by suction if necessary. 

1. Before installing the brake pads, check the amount of wear on the brake discs.

   For details of minimum brake disc thickness, see → 4600TW TECHNICAL DATA/BRAKE WEAR LIMIT - 911 TURBO/GT2/GT3/GT3RS .

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. Remove protective paper completely from the brake-piston damping plate (on the brake pad mounting plate) -1-  before installing the brake pads.

4. Fit new disc brake pads.
5. 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.).
