Removing and installing the parking brake shoes: Installation

Lightly grease the adjustment device (No. 2), pins (No. 8/No. 9.) on the actuating lever (spreading lever) and the sliding surfaces of the parking brake shoes.
Install the actuating lever (spreading lever) (No. 12), brake shoes, return springs, compression springs and adjustment device. The spreading lever (No 12.) is a 1-part assembly that cannot be disassembled. This assembly consists of part Nos. 6, 7 and 8.
NOTE: The hook (the curved end of the spring) of compression spring No. 10 must point upward on the upper brake shoe and downward on the lower brake shoe (arrows / see Figure ).
Again check to ensure that the parking brake shoes, adjustment device, return springs, compression springs and spreading lever are positioned correctly, and adjust if necessary.
NOTE: Ensure that the hooks (curved spring ends) of the compression springs (No. 10) correctly clasp the wheel carrier A (if necessary, check with the aid of a mirror).

Clean the levelling and centering surfaces on the brake disc and wheel hub. Then apply a very thin coat of Optimoly TA to the centering surface on the wheel hub.
Fit the brake disc (right and left brake discs are the same part / exception GT3).
Notes only for 911 GT3

Do not confuse right and left brake discs during assembly.

Distinguishing characteristic: Involute shape and spare part number (SP No.).

The flat surface of the brake discs is marked with R = right or L = left.

Spare part on left-hand side third group number is odd

Spare part on right-hand side third group number is even

Example:

SP No. Left brake disc: 996.352.405.00

SP No. Right brake disc996.352.406.00:

Adjust the parking brake shoes and the parking brake cables (ADJUSTING THE PARKING BRAKE SHOES ). Fit the brake caliper. Tightening torque of the fastening screws: 85 N.m (63 ftlb.). Ensure that the brake hose and brake line are in a perfect position.
NOTE: Replace the brake caliper fastening screws after each removal.

On the 911 GT3, the brake caliper fastening screws on the front and rear axle are 5 mm longer than on the 911 Carrera (996). The screws are also different colours.

911 GT3 = red (77 mm long)

911 Carrera (996) = silver (72 mm long).
