A brake caliper, for example a floating caliper, with a caliper housing and a guide element. The guide element fixed on one side to the caliper housing and moveably supported at a free end in a guide bushing. The guide bushing having a return mechanism that deflects with and returns the guide element to an initial position. The return mechanism also automatically adjusts when the guide element exceeds a predetermined amount of deflection.

Disclosed is a wet friction member for use in a wet clutch that can achieve an increased coefficient of static friction (μs) between it and a counterpart surface in frictional contact with it. The wet friction member includes base paper that is formed using a fiber base material and a filler, and a binder for curing the base paper. The filler includes rubber particles made of at least one kind of highly lipophilic rubber material. The rubber particles contains carbon black for reinforcement.

A friction material for a brake pad comprises a fibrous base material without a metal fiber, and comprises a binder and a friction modifier. The friction material comprises 0.3% to 2.0% by weight, relative to the entire friction material, of a non-crosslinkable polyolefin having a melting point higher than the melting temperature of the binder. The friction material can suppress increase in friction coefficient of a friction material during initial brake operation and reduce the occurrence of abnormal effects and squealing in low-temperature and high-humidity environments.

A pressure plate for a friction coupling such as a clutch or brake system is disclosed in the present application. The pressure plate includes one or more pockets with a phase change material disposed therein. The phase change material operates to absorb and release heat when the friction coupling cycles between activation and deactivation so as to minimize a maximum temperature of the pressure plate.

A method for producing a columnar or cylindrical metal automotive part whose outer circumferential surface includes a portion to be coated with paint and a portion to be uncoated therewith includes the following processes: (1) a process of providing a convergent nozzle-shaped covering jig which covers an outer circumferential surface of the columnar or cylindrical part at an axial end thereof and covers the portion to be uncoated with the paint, with a gap formed between the covering jig and the outer circumferential surface of the part; (2) a process of discharging a gas from the gap toward an end of a nozzle of the covering jig with the columnar or cylindrical part being rotated; (3) a process of sticking a film-forming substance to the columnar or cylindrical part from an axial side surface thereof.
