Rear Disc Brake

Rear Disc Brake

COMPONENT LOCATION








INTRODUCTION
The rear braking system on both the naturally aspirated and supercharged vehicles features 326 x 20 mm (12.83 x 0.79 in) diameter ventilated brake discs with aluminum, single acting piston, sliding calipers.

The brake calipers on the supercharged vehicle are painted and also include a logo badge. The logo badge must be removed in order to renew the brake pads.

The caliper is mounted within a fixed carrier that is secured to the rear wheel knuckle with 2 bolts. When hydraulic pressure is supplied to the caliper, the piston extends to force the inner pad against the brake disc. The caliper reacts and slides along 2 guide pins to bring the outer pad into contact with the brake disc.

Each inboard brake pad is installed with a wire type anti-rattle spring.

NOTE: There is no wear indicator installed to the rear brake pads.

The brake disc is manufactured from cast iron and is of the vented type. The disc is retained on the wheel hub by 2 retaining washers and the wheel nuts.
Also incorporated into each rear brake caliper carrier is the parking brake mechanism.

Repairs

CAUTION: Do not use the 'Emergency Release' tool to allow work to be carried out on the rear brakes. Work can only be carried out on the rear brakes after the 'parking brake unjam' routine is run.

Before carrying out any work on the rear brakes, the Jaguar approved diagnostic system must be connected and the 'parking brake unjam' routine run.

When all work is carried out on the rear brakes, the parking brake system will require resetting.
