Brake Rotor/Disc: Service and Repair
Rear Brake Disc Replacement
Removal
1. Remove the rear wheel. Open the plug connection on the wheel carrier and pull out the plug for the brake pad wear indicator.
2. With a screwdriver, turn the adjustment device towards "release" through a wheel bolt threaded hole.
3. Remove the brake caliper from the wheel carrier and suspend it in the wheel arch (do not open brake hydraulics). First, pull out the electrical wires
on the brake caliper holder and the brake pad wear wire on the wheel carrier holder.
4. Take off the brake disc after removing the countersunk screws (arrows). If a stuck brake disc cannot be removed by gentle tapping with a plastic
hammer, evenly screw hexagon head bolts into the two M8 threads of the brake disc, thereby pressing off the disc.
Installation
1. Clean the leveling and centering surfaces on the brake disc and wheel hub. Then, apply a very thin coat of Optimally TA to the centering surface
on the wheel hub.
2. 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
