Porsche 996 TT, Repair Manual

Page: 1988 / 2099

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.
