Abstract: An impact tool includes a housing that includes a motor housing portion, a front housing portion coupled to the motor housing portion, and a D-shaped handle portion extending from the motor housing portion in a direction opposite the front housing portion. The impact tool includes an electric motor supported in the motor housing portion, a battery pack supported by the housing for providing power to the motor, and a drive assembly for converting a continuous torque input from the motor to consecutive rotational impacts upon a workpiece capable of developing at least 1,700 ft-lbs of fastening torque.

Abstract: This invention relates to a pad retraction spring for use in a disc brake assembly. The pad retraction spring is operative to move the friction pads from engagement with the rotor when the friction pads are in a non-braking position. The pad retraction spring is effective to apply a first force against the friction pads when the friction pads are new, and effective to apply a second force against the friction pads when the friction pads are worn. The second force is greater than the first force, and at least one of the first force and the second force by itself is not sufficient to move at least one of the friction pads from engagement with the rotor when the friction pads are in the non-braking condition.

Abstract: A slide pin bushing for use in a vehicle disc brake caliper assembly adapted to selectively frictionally engage a rotor connected to a vehicle wheel includes an anchor plate adapted to be secured to a stationary component of the vehicle, and a caliper secured to the anchor plate for sliding movement relative thereto. A pair of brake pads are carried by the disc brake caliper assembly, and an actuation system is provided for selectively moving the brake pads axially toward and away from one another so as to selectively frictionally engage the rotor. An elastomeric slide pin bushing is disposed in a non-threaded opening formed in the caliper. The slide pin bushing includes a pair of opposed ends and an intermediate body section. The intermediate body section of the slide pin bushing is provided with a cylindrical inner surface having a generally roughened textured surface finish. A generally rigid sleeve is disposed within the slide pin bushing.

Abstract: A disc brake piston includes a body formed from a plastic material and a cover formed from a metallic material. The body of the piston is molded from a synthetic resin material and is generally hollow and cylindrical in shape, defining an axis and including an opened end and a closed end. The body defines an inner cylindrical surface and an outer cylindrical surface which extend axially from the opened end toward the closed end. The cover is formed from steel and is integrally molded to the body of the piston. The cover extends about the opened end of the body and extends axially inwardly toward the closed end along portions of both the inner and outer surfaces of the body.
