Abstract: A floating caliper disc brake system includes a caliper body housing a piston that presses a brake pad against a disc and a mount that slidably holds the caliper body in a direction perpendicular to the disc. The system further includes a slide pin that guides a sliding motion of the caliper body, which is connected to a pin securing portion provided for one side of the mount. A guide hole with which the slide pin is slidably engaged is formed in the other side of the mount. The slide pin is connected to the pin securing portion through an elastic bushing to decrease a slide pin guide clearance and substantially eliminate dragging.

Abstract: A hydraulically operated brake system having a servo pressure generating device activated by a torque transmitted from a disc rotor to a braking device with a brake cylinder during activation of the braking device by an operator-controlled master cylinder, to generate a servo pressure which is applied to the brake cylinder through a pressure control valve when the servo pressure is higher than the master cylinder pressure. The pressure control valve inhibits a flow of the fluid from the braking device toward the servo pressure generating device when the servo pressure is lower than the master cylinder pressure. A by-pass passage is provided for connecting the braking device and the servo pressure generating device while by-passing the pressure control valve, and a shut-off valve is provided in the by-pass passage. The shut-off valve is open when the master cylinder pressure is lower than a predetermined level, and closed when the master cylinder pressure exceeds the predetermined level.

Bases and grooves are arranged in the inner surface of the anti-friction seat so as to extend in a direction across the peripheral edge of the opening and be alternately arranged in the circumferential direction extending along the peripheral edge of the opening. Each of the grooves is isolated from the opening by a partition wall extending between bases on opposite sides of the groove. The bases are in spherical contact with the ball section, and the grooves are filled with a lubricating agent.

Abstract: In a disc brake in which the caliper is supported by a mounting slidably in the axial direction of the rotor via a pair of pin sliding means, the pin sliding means is such that a center of the caliper side axial portions (i.e. collars) mounted rotatably and integrally movably in the axial direction in insertion holes of the caliper is eccentric with respect to the center of the mounting side axial portions (i.e. slide pins) fitted rotatably and slidably in the axial direction into the installation holes in the mounting.

Abstract: A vehicular brake apparatus includes a disc brake mechanism that brakes rotation of a wheel by pressing a friction member against a brake disc. The vehicular brake apparatus has a wall thickness detector that detects a state of wall thickness of the brake disc, and a controller that controls a state of contact between the brake disc and the friction member. Based on the state of wall thickness of the brake disc detected by the wall thickness detector, the controller controls the state of contact between the brake disc and the friction member so that the friction member contacts a relatively great wall thickness portion of the brake disc more strongly than the friction member contacts a relatively small wall thickness portion of the brake disc. The brake apparatus is able to eliminate the wall thickness variation of the brake disc or suppress occurrence of a wall thickness variation.
