Rear Brake Disc, Iron Rotors

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 11 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 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.
2. Fit the brake disc.

Note:
^ 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 (SP No. Left brake disc: 996.352.405.00).





^ Spare part on right-hand side - third group number is even (SP No. Right brake disc: 996.352.406.00).

3. Adjust the parking brake shoes and parking brake cables.
4. Fit the brake caliper. Replace the brake caliper fastening screws after each removal.
Tightening torque of the fastening screws = 85 Nm (63 ft. lbs.).
