DESCRIPTION AND OPERATION
Hydraulic Brake Actuation
CAUTION: Blistering or swelling of rubber brake components may indicate contamination
of the brake fluid by a petroleum based substance. New rubber components must be installed
in the hydraulic brake system if contaminated and the entire hydraulic brake system must be
flushed with clean brake fluid to prevent recontamination.
This vehicle is equipped with a brake pedal actuated dual brake system. The system consists of the
following:
zpower brake booster (2005)
z brake master cylinder (2140)
z brake pressure control valve (2B091)
z disc brake calipers (2B120)
z rear disc brake calipers (2553)
z brake tubes and hoses
z anti- lock brake system (ABS) components

The dual brake system is split front and rear with the front wheel brakes comprising of one circuit and
the rear wheel brakes, the other circuit.
Brake Fluid
WARNING: Brake fluid contains polyglycol ethers and polyglycols. Avoid contact with
eyes. Wash hands thoroughly after handling. If brake fluid contacts eyes, flush with running
water for 15 minutes. Get medical attention if irritation persists. If taken internally, drink water
and induce vomiting. Get medical attention immediately.
Clean, fresh Ford High Performance DOT 3 Brake Fluid C6AZ-19542- AB or equivalent DOT 3 fluid
meeting Ford specification ESA- M6C25-A is the only brake fluid that should be used in Ford vehicles.
z Do not reuse brake fluid drained or bled from the system.
z Do not use brake fluid that has been stored in an open container.
z Do not mix different types of brake fluid.
Brake Master Cylinder
The brake master cylinder is a dual piston type. The brake master cylinder operates as follows: zWhen the brake pedal (2455) is depressed, pressure is applied by mechanical linkage to the
primary and secondary piston.
z Brake master cylinder pistons apply hydraulic pressure to the two hydraulic circuits.
z Brake master cylinder will not be overhauled, a new master cylinder is installed only.
The brake master cylinder consists of:
zbrake master cylinder reservoir (2K478)
z brake master cylinder body
Brake Master Cylinder Reservoir
NOTE: Whenever the brake master cylinder reservoir is removed from the brake master cylinder, new
grommets must be installed.
The brake master cylinder reservoir :
zis mounted to the brake master cylinder.
z holds fluid supply for each brake master cylinder hydraulic piston.
z provides visual fluid level markings.
z contains the brake master cylinder fluid level sensor. Klj . 2 ba
