In order to prevent a needlessly excessive yaw moment from being applied to the vehicle, thereby improving the running stability of the vehicle when either one of the braking force generation units went wrong, a brake system for vehicles having electric brake units ( ) each provided for each of the wheels to generate a braking force by its actuator ( ) being driven according to the amount of depression of a brake pedal, and a controller ( ) for controlling each of the electric brake units independently of others, is so constructed as to judge if any of the electric brake units went wrong (step ), and when either one of the electric brake units went wrong, to control the electric brake units other than the wrong unit according to the depression amount of the brake pedal so as to accomplish a best available stability of running of the vehicle.

Brake system for vehicles

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.
