GENERAL
The front brakes on all models feature ventilated brake discs, with different diameter brake discs for each model. All models except 5.0L SC feature twin piston sliding calipers. On 5.0L SC models, 6 piston, opposed piston Brembo calipers are installed.
On all models the brake caliper is attached to the rear of the front knuckle. The brake pads are made from an asbestos free material. The inboard brake pad of the left front brake incorporates a wear sensor.
With the standard brake sliding calipers, when hydraulic pressure is supplied to the caliper, the pistons extend and force the inner pad against the brake disc. The caliper body reacts and slides on the guide pins to bring the outer pad into contact with the brake disc.
With the high performance fixed calipers, when hydraulic pressure is supplied to the caliper, the three pairs of opposed pistons extend in the caliper. The three pistons in each side of the caliper force their related brake pads against the brake disc.
The front brake pad wear sensor is connected in series with the rear brake pad wear sensor, between the instrument cluster and ground. When a brake pad incorporating a brake pad wear sensor is approximately 75% worn, 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 Instrument Cluster
At the beginning of each ignition cycle, the instrument cluster performs a bulb check on the brake warning indicator: the indicator is illuminated amber for 1.5 seconds, red for 1.5 seconds, then goes off.
