Hydraulic Brake Actuation





WARNING: BRAKE FLUID CONTAINS POLYGLYCOL ETHERS AND POLYGLYCOLS. AVOID CONTACT WITH THE EYES. WASH HANDS THOROUGHLY AFTER HANDLING, AS PROLONGED CONTACT MAY CAUSE IRRITATION AND DERMATITIS. IF BRAKE FLUID CONTACTS THE EYES, FLUSH THE EYES WITH COLD WATER OR EYEWASH SOLUTION AND SEEK MEDICAL ATTENTION. IF TAKEN INTERNALLY, DO NOT INDUCE VOMITING, SEEK IMMEDIATE MEDICAL ATTENTION. 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 brake master cylinder.
^ Front brake discs.
^ Front brake disc calipers.
^ Rear brake discs.
^ Rear brake disc calipers.
^ 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 fluid reservoir with integral fluid level warning indicator.

Adjustable Pedals
The adjustable pedal system comprises of a throttle pedal assembly with an adjustment motor and drive cables. The drive cables are attached to the brake and clutch adjustment mechanisms. The pedals move forward and rearward together. Two separate pedal positions can be set and stored in the memory for driver recall. The pedal position adjustment is by a switch fitted on the steering column shroud.
