Hydraulic System: Description and Operation

DESIGN
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. Two different brake systems are available:

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 tubing and flexible hoses to the rear wheel cylinders and the 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 on 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.

FOUR-WHEEL DISC 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 tubing and flexible hoses to the front disc brake calipers and rear disc brake calipers. The brake fluid enters the calipers, forcing the pistons outward against the brake pads and lining. The brake pads press against the braking surface on the brake rotor. When the brake pedal is released the pressure is relieved, returning the front disc brake caliper pistons to the unapplied position.
