4 Caliper Carrier
5 Caliper Guide Pins
6 Guide Pin Dust Caps
7 ABS Sensor
8 Hub Carrier
9 Hydraulic Hose

The rear disc brake rotor is mounted directly behind the wheel and hub. It is of the ventilated type and measures 305mm diameter and 28mm thick. The single piston sliding caliper is mounted on the carrier by means of two guide pins and a caliper retaining clip. The guide pins slide in bushes installed in the caliper body which also houses the brake pads.

The bushes have dust caps, which must always be installed when reassembling the caliper. The carrier is installed on the rear hub carrier and secured by two bolts. An ABS sensor connector is also mounted on top of the hub carrier. The hydraulic hose port of the caliper faces inboard and an armored hose is installed. The rear disc brake rotor is mounted directly behind.

When hydraulic pressure is generated in the caliper due to a brake application, the caliper piston moves one of the brake pads into contact with the brake rotor. The caliper body is free to move on the two guide pins, which allows it to center itself to the brake rotor. This causes the other brake pad to contact the brake rotor with equal pressure. The greater the hydraulic pressure in the caliper, the harder the brake pads grip the brake rotor.
