Rear Brakes

GENERAL
All models feature the same rear disc brake, consisting of a single piston brake caliper, a ventilated brake disc and a dust shield (integrated as part of the parking brake).

The brake caliper is attached to the rear of the hub. The brake pads are made from an asbestos free material. The inboard brake pad of the right rear brake incorporates a wear sensor.

When hydraulic pressure is supplied to the caliper, the piston extends and forces the inner pad against the disc. The caliper body reacts and slides on the guide pins to bring the outer pad into contact with the disc.

The rear brake pad wear sensor is connected in series with the rear brake pad wear sensor, in a circuit connected to the instrument cluster. 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 brake warning indicator (red), displays an appropriate warning in the message center and sounds a warning chime.

At the beginning of each ignition cycle, the instrument cluster performs a 2 second bulb check of the brake warning indicator. The indicator is illuminated amber for 1 second then red for 1 second.
