Rear Disc Brake

A = Hardwired
BRAKE CALIPERS
When hydraulic pressure is supplied to the caliper, the pistons extend to force the inner pad against the brake disc. The caliper reacts and slides along two guide pins to bring the outer pad into contact with the brake disc.
BRAKE PAD WEAR SENSORS (Standard and Performance Brakes Only)
When a brake pad incorporating a brake pad wear sensor is approximately 75% worn, the sensor wire within the pad material is worn through and the brake pad wear sensor goes open circuit. When the instrument cluster detects the open circuit, it illuminates the amber LED (light emitting diode) in the brake warning indicator, displays an appropriate warning in the message center and sounds a warning chime. For additional information refer to 413-01 Instrument Cluster.
NOTE:
New pad wear sensor leads need to be fitted whenever the brake pads are changed irrespective of the brake pad warning sensor being triggered.
BRAKE CALIPERS
Each caliper is mounted within a fixed carrier that is secured to the rear wheel knuckle with two bolts. Each inboard brake pad is installed with a wire anti-rattle spring. On SC (supercharger) vehicles a badge with the 'R' symbol is retained on the caliper housing with 2 screws.
On vehicles with standard and performance brakes, the inboard brake pad of the RH (right-hand) brake incorporates a wear sensor.
Also incorporated into each rear brake caliper carrier is the parking brake mechanism. For additional information refer to 206-05 Parking Brake and Actuation.
BRAKE PAD WEAR SENSORS (Standard and Performance Brakes Only)
The brake pad wear sensor is wired in series with a wear sensor on the LH (left-hand) front brake and the instrument cluster. If the thickness of one of the brake pads connected to a wear sensor decreases to a predetermined limit, the instrument cluster illuminates the brake warning indicator.
NOTE:
New pad wear sensor leads need to be fitted whenever the brake pads are changed irrespective of the brake pad warning sensor being triggered.
