1. Check that all parts are in perfect condition and replace them if necessary.
2. Clean the levelling and centring surfaces on the brake disc and wheel hub.
3. Apply a very thin coat of Optimoly TA to the centering surface on the wheel hub.
4. Fit the brake disc.
Note
•
Replace the brake caliper fastening screws after each removal!
•
The brake caliper fastening screws of the GT2 and Turbo with PCCB are 8 mm longer (85 mm) than
on the 911 Turbo with cast iron brake discs (77 mm)!
5. Fit brake caliper with new fastening screws. Tightening torque of the fastening screws = 85 Nm (63 ftlb.).
6. Mount wheel. For a wheel installation, 2 assembly aids (assembly pins) must be screwed into the
wheel hub!
Note on bedding in the new brake pads
New brake pads require a slightly longer bedding−in period for PCCB brake discs than cast iron brake discs.
In general, the following applies: New brake pads must be worn in (bedding−in period), their optimum
braking effect is therefore not reached until after a few hundred kilometers. The slightly reduced braking
effect must be compensated for by increased pressure on the brake pedal. The same also applies after a brake
disc change.
