Abstract
Typically, a disc brake the caliper assembly is mounted by a pair of specially configured mounting bolts to a cast-iron steering knuckle. In many models, the bolts are threadingly engaged with a steering knuckle or similar support structure in order to retain the bolts in place. To remove the caliper assembly, the two caliper mounting bolts are removed. However, in many instances, during servicing of the disc brakes, the threads within one of the apertures defined in the steering knuckle become stripped. A caliper mounting replacement bolt is provided having oversized self-tapping threads and an associated aperture for auxiliary retention. The inventive replacement bolt is used in place of the original caliper mounting bolt to enable reinstallation of the brake caliper assembly onto the steering knuckle in a quick and efficient manner. During the installation thereof, the inventive mounting bolt cuts a new thread into the steering knuckle aperture. In addition to the threading engagement with the steering knuckle, auxiliary bolt retention is provided, preferably, via use of a cotter pin.
