2007 Ford Mustang Brake Service (ONLINE REPAIR MANUALS)

Remove wheels and inspect brake disc, calipers and linings.

If the caliper is cracked or fluid leakage through the casting is evident, it must be replaced as a unit.

If caliper was removed when installing new components, clean all components in alcohol, then wipe dry using lint-free cloths. Using an air hose, blow out drilled passages and bores. Inspect dust boots for punctures or tears. If punctures or tears are evident, install new boots during assembly.

Inspect piston bores in both housings for scoring or pitting. Bores showing light scratches or corrosion can usually be cleaned with...

System Depressurizing

On models equipped with anti-lock brakes, hydraulic system must be depressurized prior to ...

Brake Roughness

Thickness Variation

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 edge of disc. If thickness measurements vary by more than .0005 inch, replace the disc.

Lateral Runout

Excessive lateral runout of braking disc may cause a knocking back of the pistons, possibly creating increased pedal travel and vibration when brakes are applied.

Wheel Bearing Looseness

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...
