Ford Focus Service Manual: Hydraulic Brake Actuation
The hydraulic brake actuation system consists of the following components:
- Brake master cylinder and fluid reservoir
- Brake pedal and bracket
- Brake tubes and hoses
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 double-walled steel tube and flexible hoses to the front brake calipers and rear wheel cylinders. The brake fluid enters the calipers and cylinders, forcing the pistons and brake pads/shoes outward against the friction surface, slowing or stopping rotation. When the brake pedal is released, brake fluid pressure is relieved, returning the caliper pistons, wheel cylinders, brake pads and brake shoes to the unapplied position.
