Front Disc Brake Pads For PCCB Rotors

Removing and Installing the Front Disc Brake Pads - GT2

WARNING:
Danger of accident if brake pads with the wrong brake pad quality are installed.
- Use only the type-specific brake pads in the Porsche Spare Parts Catalogue.

NOTE:
- The GT2 is equipped with PCCB (Porsche Ceramic Composite Brake) as standard.
- In contrast to this, at the start of production, steel brake discs and brake pads are used at first.
- The pad backing plates (rear side of the brake pads) must not be greased.





- 2 vibration dampers -arrows- are fitted on each of the brakepad supports. No other damping measures are present (not necessary).


Removal

CAUTION:
PCCB (Porsche Ceramic Composite Brake): Danger of material damage during wheel removal-installation (danger of damage to brake discs).
- Use assembly aids (assembly pins) in order to exclude any possibility of heavy contact of the wheel with the brake disc. The assembly aids (2 assembly pins) are located in the luggage compartment.





1. Screw the 2 assembly aids (assembly pins), instead of 2 wheel bolts, into the wheel hub before wheel removal-installation. During removal, first remove the 3 remaining wheel bolts and remove the wheel carefully, without touching the brake discs.





2. Undo the screw on the retaining pin. Counter the retaining pin when doing this.





3. Pull out the retaining pin towards the inside.
4. Pull out the warning contact wire on the brake caliper and remove the warning contacts from the brake pad plates.

NOTE:
- Replace warning contacts if the core of the wire is worn or worn through.
- The warning contact can continue to be used if there are only scrape marks on the plastic part of the warning contact.
- If necessary, remove some brake fluid by suction from the brake fluid reservoir (brake fluid may escape over the rim of the container).





5. Pull out the brake pads. If necessary, first set back the brake pads as far as necessary with the piston resetting fixture (press back).


Installation

WARNING
Danger of accident if old parts are fitted on brake caliper.
- Fit new expanding spring and new retaining pin with a new screw on the brake caliper.

NOTE:
- Ensure correct brake pad quality. Use brake pads as per Spare Parts Catalogue.
- The pad backing plates (rear side of the brake pads) must not be greased.





- For a wheel installation, 2 assembly aids (assembly pins) must be screwed into the wheel hub.

1. If necessary, turn back the piston to its original position using the resetting fixture.
2. Insert the brake pads.





3. Fit new expanding spring and new retaining pin with a new screw on the brake caliper. These parts are available as a repair set and must be renewed each time the pads are changed. When tightening the screw, counter at the retaining pin. Tightening torque of the screw = 25 ± 3 Nm (19 ± 2 ftlb.)
4. Insert the warning contact wire and warning contacts.
5. Firmly press the brake pedal several times to position the brake pads on the brake discs.
6. Check and, if necessary, correct the brake fluid level.

Bedding in the brake pads
- New brake pads require a bedding-in period of approx. 200 km. Not until then do they achieve their best friction and wear coefficient.
- During this period, the brakes should be subjected to full stress when travelling at high speed only in emergencies.
