Brakes and Traction Control: Description and Operation
Brake SystemThe brake system has the following components:
^ Fixed position foot pedal
^ Vacuum-assisted power brake booster
^ Diagonal split hydraulic system
^ Front disc brakes
^ Rear disc brakes
^ Drum-in-hat park brake system
^ ABS hydraulic control unit (HCU).
The brake pedal is connected to the power brake booster, which is connected to the brake master cylinder. When the brake pedal is pressed, brake fluid is pushed through the doubled-walled steel tubes and flexible hoses to the front and rear disc brake calipers. The brake fluid enters the disc brake calipers, forcing the caliper pistons and brake pads outward against the brake disc friction surface, slowing or stopping rotation. When the brake pedal is released, brake fluid pressure is relieved, returning the front and rear disc brake caliper pistons and brake pads to the unapplied position.
