Brake System - VIN Range: G45704->G99999
Brake System - VIN Range: G45704->G99999WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with the eyes. Wash hands thoroughly after handling, as prolonged contact may cause irritation and dermatitis. If brake fluid contacts the eyes, flush the eyes with cold water or eyewash solution and seek medical attention. If taken internally do not induce vomiting, seek immediate medical attention. Failure to follow these instructions may result in personal injury.
The braking system is a diagonally split, dual circuit design featuring front and rear disc brakes.
The hydraulic system provides separate circuits for each pair of diagonally opposed wheels (left front, right rear and right front, left rear).
The standard front brake caliper has two retaining bolts that attach the brake caliper to the anchor plate. These are of single, sliding piston type. The anchor plate is attached to the wheel knuckle with two bolts. The standard brake disc is manufactured from cast iron and is of the vented type. It is retained on the hub by two retaining clips and the wheel studs.
The high performance front brake caliper has two retaining bolts that attach the brake caliper to the anchor plate. These are of single, sliding piston type. The anchor plate is attached to the wheel knuckle with two bolts. The high performance brake disc is manufactured from cast iron and is of the vented type. It is retained on the hub by two retaining clips and the wheel studs.
The rear brake calipers are single pistoned floating caliper type, which also incorporates the park brake mechanism. In addition, the high performance caliper has a logo badge which has to be removed when changing the brake pads. The brake disc is manufactured from cast iron and is of the vented type. It is retained on the hub by two retaining clips and the wheel studs.
The brake pads in all cases are asbestos free.
Braided steel brake hoses are fitted to reduce expansion under braking pressure and are of a light weight design.
The brake master cylinder is of a tandem design and is linked to a brake booster to reduce the brake pedal effort. The tandem design will make sure that in the event of one brake circuit failure the other will remain fully operational. The brake booster operating rod is connected directly to the brake pedal.
The parking brake module is located in the luggage compartment behind the right-hand rear luggage compartment trim panel and operates the rear brakes through a motor and cable system.
Principles of Operations
The brake system operates by transferring effort applied to the brake pedal, by the driver to the brakes at each wheel.
The braking effort is distributed to each wheel, using a hydraulic system. The system is assisted using a vacuum brake booster that reduces pedal effort for a given hydraulic pressure. The parking brake operates on the rear wheels and is applied using a pull/push switch mounted on the floor console. The adjustable pedal system allows adjustment of the throttle, brake and clutch pedals by a switch fitted on the steering column shroud.
