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.

One-piece garter spring coupling release tool. The release tool is molded in a single selectively configured shape out of a durable, flexible plastic material such as Elastollan.TM. S98A available from Elastogran of Germany. The release tool generally comprises a cylindrical body with a slot along its length and a flange on one end. The slot permits the tool to be positioned around a port to which a garter spring coupling is connected; the flange provides an area for gripping the tool to releasably engage the tool with its coupling. The flexible, slotted configuration of the garter spring coupling release tool permits nesting of a four-piece set of such tools within each other to facilitate packaging, storage and retention of the tools as a set.

A replacement closure assembly for the drain hole of a fluid reservoir is disclosed. The assembly is comprised of a threaded shaft portion which includes a clamping member at one end thereof and a backing member at the other end thereof. A sealing member is provided between the clamping member and the backing member and is dimensioned to close the drain hole opening. In the preferred embodiment, the clamping member is formed about a threaded pivot member which is secured on the threaded portion of the shaft. In use, the clamping member is passed through the drain hole and brought into engagement with the interior of the reservior. The shaft is then threaded through the clamping member until the sealing member is urged into contact with the drain hole. The backing member provides a continuous contact between the sealing member and the reservoir.
