General Information

1 Brake Rotor
2 Caliper
3 Caliper Guide Pins
4 Caliper Carrier
5 Caliper Retaining Clip
6 Guide Pin Dust Caps
7 Rotor Shield

The front disc brake rotor is mounted on the wheel lug studs directly behind the wheel and is clamped between the wheel and hub. It is of the ventilated type and measures 305 mm diameter and 28 mm thick.

The single piston caliper is mounted on a carrier by means of two guide pins and a caliper retaining clip. The carrier is installed on the suspension vertical link by two bolts. An ABS sensor connector is also mounted at the front of the vertical link. The guide pins slide in bushes installed in the caliper body. The bushes have dust caps, which must always be installed when reassembling the caliper.

The hose port of the caliper faces towards the front of the vehicle and armored hoses are installed. A rotor shield is installed and may be removed without disturbing the hub bearings. The brake pads are installed in the caliper body.

When hydraulic pressure is generated in the caliper due to a brake application, the piston pushes 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 centralize 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 the harder the brake pads grip the rotor.
