Brake System - Description & Operation (VIN Range: M45255->N52047)
| WARNING | BRAKE DUST, IF INHALED CAN DAMAGE YOUR HEALTH. ALWAYS REMOVE BRAKE DUST USING A VACUUM BRUSH. DO NOT USE A COMPRESSED-AIR LINE TO DISPERSE BRAKE DUST INTO THE ATMOSPHERE. Failure to follow this instruction may result in personal injury. |
| CAUTION | Brake pads must always be replaced in axle sets. |
| CAUTION | Replacement of nuts and bolts: Various thread-locking devices are used on nuts and bolts throughout the vehicle. These devices restrict the number of times a nut or bolt can be used. Refer to General Service Information article. |
| CAUTION | The high performance brake caliper is aligned to the brake disc when it is first installed to the vehicle, therefore, care must be taken not to disturb this alignment. When removing the caliper; remove the bolts that secure the anchor bracket to the vertical link only. DO NOT loosen any other caliper bolts. |
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 double, sliding piston type which makes sure equal effort is applied through both brake pads. The anchor plate is attached to the wheel knuckle with two bolts. The standard rear brake calipers are single piston floating caliper type, which also incorporates the park brake mechanism. 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.
In vehicles fitted with high performance brakes, the front and rear brake calipers have two retaining bolts that attach the brake caliper to the wheel knuckle. These are four piston fixed type which makes sure that equal effort is applied through both brake pads. The rear brakes have separate brake calipers for the parking brake. 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 now fitted to reduce expansion under braking pressure and are 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 electric parking brake (EPB) control is located in the floor console and operates the rear brakes through a motor and cable system.

| WARNING | 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. |
