Sliding caliper rear disc brakes are used on Continental, Mark VII, Mark VIII, Mustang and Thunderbird, Figs. through . The caliper is basically the same as the larger front wheel caliper; however, a parking brake mechanism and a larger inner brake shoe anti-rattle spring have been added.

The parking brake lever, located at the rear of the caliper, is actuated by a cable system similar to rear drum brake applications. When the parking brake is applied, the cable rotates the lever and operating shaft, driving the caliper ...

BRAKE ROUGHNESS

The most common cause of brake chatter on disc brakes is a variation in thickness of the disc. 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. To check for this condition, 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 ...
