Disc/Drum Actuation

The brake pedal is connected to the brake master cylinder. When the brake pedal is depressed, brake fluid is pushed through the double-walled steel lines and flexible hoses to the rear wheel cylinders and the rear disc brake caliper. The brake fluid enters the rear wheel cylinder, forcing the rear wheel cylinder pistons outward against the brake shoe and lining. The brake shoe and lining press against the braking surface of the brake drum. The front disc brake caliper pistons are forced outward against the brake shoe and lining, and contact the braking surface of the front disc brake rotor. When the brake pedal is released, the pressure is relieved, returning the front disc brake caliper pistons and rear wheel cylinder pistons and the brake shoe and lining to the unapplied position.
