Hydraulic System: Description and Operation

Hydraulic Brake Actuation





WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with the eyes. Wash hands thoroughly after handling. If brake fluid contacts the eyes, flush the eyes for 15 minutes with cold running water. Get medical attention if irritation persists. If taken internally, drink water and induce vomiting. Get medical attention immediately. Failure to follow these instructions may result in personal injury.

The hydraulic brake system is of a pedal operated, diagonally split dual line brake system that consists of the following components:
^ A brake booster.
^ A master cylinder.
^ Front disc brake calipers.
^ Front brake discs.
^ Rear disc brake calipers.
^ Rear brake discs.
^ Rear drums (2.0L).
^ Rear wheel cylinders (rear drum brakes, 2.0L).
^ Brake tubes and hoses.
^ Anti-lock brake system (ABS).

Brake Master Cylinder
The brake master cylinder is a dual piston type. The master cylinder operates as follows;
^ When the brake pedal is applied, pressure is applied by mechanical linkage to the primary and secondary systems.
^ Brake master cylinder pistons apply hydraulic pressure to the two circuits.

The master cylinder consists of the following components:
^ Primary and secondary pistons.
^ Brake master cylinder reservoir with integral fluid level warning indicator.

Dual Hydraulic Brake System
The dual hydraulic brake system is a conventional pedal actuated system. The system consists of the following components:
^ Brake master cylinder reservoir with fluid level indicator.
^ Anti-lock brake system Hydraulic Control Unit (HCU).
^ Brake tubes and hoses.
^ A brake master cylinder.
^ Diagonally split brake circuits (left-hand front to right-hand rear and right-hand front to left-hand rear).
