Hydraulic Brake Actuation

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

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 from the master cylinder through the steel tubes, HCU, pressure control valve (non-hybrid vehicles only) and flexible hoses to the front brake calipers and rear wheel cylinders. When the brake pedal is released, brake fluid pressure is relieved, returning the front and rear brake components to the unapplied position.
