2004 Ford Mustang Brake Service (ONLINE REPAIR MANUALS)

If roughness or vibration is encountered during highway operation or if pedal pumping is experienced at low speeds, the disc may have excessive thickness variation. Measure the disc at 12 points with a micrometer at a radius approximately one inch from the edge of the dis...

Disc brake service is critical because of the close tolerances required in machining the brake disc to ensure proper brake operation.

Maintaining close control of the shape of the rubbing surfaces is required to prevent brake roughness. In addition, the surface finish must be non-directional and maintained at a micro-inch finish. This is required to avoid pulls and erratic performance, and to promote long lining life and equal lining wear of both the lefthand and righthand brakes.

Do not attempt to refinish the rubbin...

This system operates on the same principles as conventional front and rear split systems using primary and secondary master cylinders moving simultaneously to exert hydraulic pressure on their respective systems, Fig. .

The hydraulic brake lines on this system, however, have been diagonally split front to rear (left front to right rear and right front to left rear) in place of separate lines to the front and rear wheels.

In the event of a system failure this would cause the remaining good system to do all the braking on one front wheel and the opposite rear wheel, thus maintaining 50%...

Bendix Diaphragm System

These units are of the vacuum suspended system. Some units are of the single diaphragm system, while others are of the tandem diaphragm system. Both single piston and double piston or split system master cylinders are used.

The vacuum suspended diaphragm system units utilize engine manifold vacuum and atmospheric pressure for its power. It consists of three basic elements combined into a single power unit. The three basic elements of the single diaphragm system are:

• Vacuum power section which includes front and rear shell, power diaphragm, return spring and push...

On models with anti-lock brakes, the brake hydraulic system must be depressurized before disconnecting any hydraulic lines or fittings. Depressurize the system by pumping the brake pedal at least 25 times with the ignition in the Off position.
