Brake Pedal Assy: Description and Operation
Hydraulic Brake Actuation
The hydraulic brake actuation system consists of the following components:
-
Brake master cylinder
-
Brake pedal and bracket assembly
-
Brake tubes and hoses
The hydraulic brake system is diagonally split with the LH front and RH rear brakes on one circuit and the RH front and LH rear brakes on the other
circuit.
Hydraulic Brake Actuation
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 double-walled steel tubes and flexible hoses to the front brake calipers and rear wheel cylinders. The
brake fluid enters the brake calipers and wheel cylinders, forcing brake pads and shoes outward against the brake disc/drum friction surfaces, slowing or
stopping rotation. When the brake pedal is released, brake fluid pressure is relieved, returning the front and rear brake components to the unapplied
position.
