Abstract: A disc brake rotor produced by a machining method includes a friction disc having generally parallel inner and outer machined friction faces adapted to be frictionally engaged by a pair of brake pads of the disc brake assembly. Each of the inner and outer machined friction faces includes a spiral machining groove formed therein. When viewed from their respective faces, the spiral machining grooves are essentially identical to one another. The spiral machining groove formed in one of the inner and outer machined friction faces is operative during braking to produce a first force in one radial direction on one of the pair of brake pads. The spiral machining groove formed in the other one of the inner and outer machined friction faces is operative to produce a second force which is generally equal and in an opposite direction to the first on the other one of the pair of brake pads.

Abstract: A limited slip differential includes a case which is rotatably driven by a power source. A cross shaft is mounted within the case for rotation therewith. A pair of pinion gears are rotatably mounted on the ends of the cross shaft. The pinion gears mesh with side gears splined onto respect axle shafts. Thus, when the case is rotated, torque is transmitted through the cross shaft, the pinion gears, and the side gears to the axle shafts. A pair of Belleville springs are mounted to the cross shaft adjacent to the pinion gears. A hollow cylindrical spacer is disposed about the cross shaft between the two Belleville springs. The Belleville springs react against the ends of the spacer to urge the pinion gears apart from one another into frictional engagement with respective thrust washers disposed between the pinion gears and the case. As a result, the rotation of the pinion gears is restricted, thus limiting the free wheeling action of the differential.
