Description and Operation The braking system is of a diagonally split, dual circuit design featuring front and rear disc brakes. The hydraulic system has separate circuits for each pair of diagonally opposed wheels (left front, right rear and right front, left rear). The front brake caliper is of a single sliding piston design which makes sure that equal effort is applied through both brake pads. The parking brake control operates the rear brakes through a cable system. The brake master cylinder is of a tandem design and is linked to a brake booster which reduces the brake pedal effort. The tandem design will make sure that in the event of one brake circuit failing the other will remain fully operational. The brake booster vacuum on vehicles with diesel engine is provide by a camshaft driven vacuum pump. The anti-lock brake system (ABS) is controlled by the hydraulic control unit (HCU), incorporated within the hydraulic system, and only operates when the wheel speed sensors detect the onset of wheel lock up. |
