A need has developed to provide an improved assembly for mounting a dual brake disc resurfacing tool to the brake caliper mounting bracket on the hub of an automobile wheel. Such an assembly should provide adjustability of the mounting mechanism, while assuring balance and positive optimum mounting of the fixture on the brake caliper support brackets.
It is therefore an object of the invention, generally stated, to provide an improved mechanism for positively and adjustably mounting a dual brake disc resurfacing tool to the brake caliper mounting bracket of an automobile wheel hub assembly.
The invention is directed to a portable brake disc resurfacing tool which is adapted to be mounted on automobile brake caliper mounting bracket for resurfacing a brake disc adjacent the bracket without removing the disc from its mounted position on an automobile. The resurfacing tool includes a framework, adjustable means for mounting the framework on the brake caliper mounting bracket, and opposed dual cutting tools for cutting opposing surfaces on a brake disc. The tool additionally includes tool mounting means for selectably mounting the cutting bits thereon, and means for slidably mounting the tool mounting means on the framework. An improvement resides in an adjustable means for mounting the framework on the brake caliper mounting bracket. The improvement comprises a pair of opposed mounting arms with each arm including a distal end having a first aperture therethrough for aligned mounting with one of two apertures on a brake caliper mounting bracket. A base end of the mounting arm is spacially related from the distal end and includes a pair of opposing surfaces adapted to slidably mount the base end along a first channel on the framework. The improvement further includes means for adjustably fixedly securing each arm along the channel, and means for limiting the travel of one of the arms along the channel relative to the travel of the other of the arms along the channel.
