Hydraulic System: Description and Operation

Hydraulic Brake Actuation
The hydraulic brake actuation system consists of the following components:
^ ABS components
^ Brake master cylinder
^ Brake pedal (fixed or adjustable)
^ Brake tubes and hoses
^ Front disc brake calipers
^ Rear disc brake calipers

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 tube 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.
