NOTICE
Removing/fitting wheels
- Risk of damage to (ceramic) brake discs
-> Use two assembly pins when removing and fitting the wheel.
-> Carefully guide the wheel towards the wheel hub, thereby preventing any heavy impact on the (ceramic) brake disc.
1. Screw the two assembly aids (assembly pins) -1- , instead of two wheel bolts, into the wheel hub before removing/fitting the wheel. During removal, first remove the three remaining wheel bolts and remove the wheel carefully without touching the brake discs.

Subsequent work
Information
When replacing the brake discs and/or brake shoes, the brake shoes for the electronic parking brake (EPB) must be ground down. The routine is initiated using the Porsche System Tester.-> 468350 Reworking parking-brake shoes Procedures
It is not necessary to grind down the brake discs if you are simply removing/installing the brake discs.
- Set the brake discs to the basic setting if necessary and calibrate the system. -> 468315 Adjusting and calibrating brake Adjustments
