A floating disc brake includes an outer pad disposed on an axially outer side relative to a rotor, an inner pad disposed on an axially inner side relative to the rotor, a fixing member disposed on the axially inner side relative to the rotor, the fixing member being configured to support the inner pad to be movable in an axial direction and being fixed to a vehicle body, and a yoke supported to the fixing member by a slide pin to be movable in the axial direction, the yoke supporting the outer pad. The fixing member is provided with an anchor disposed on a radially outer side relative to the rotor, the anchor being configured to bear a brake tangential force that acts on the outer pad at the time of braking within a circumferential range of a lining constituting the outer pad.

Floating-type disc brake

A floating disc brake includes a yoke supported to the support in an axially movable manner, the yoke including a pad support portion that supports an outer pad on an axially outer side of the outer pad. The outer pad includes, on its axially outer surface, a pair of pad-side engagement portions formed of an elastic material. The pad support portion has a support hole that is open on at least an axially inner surface of the pad support portion, and the support hole is provided with a pair of yoke-side engagement portions on inner side surfaces of the support hole that face each other in a circumferential direction. The pair of pad-side engagement portions and the pair of yoke-side engagement portions are concavo-convex engaged with each other in the circumferential direction.

Floating disc brake and method for assembling same

A wedge cam brake executes a braking operation by causing proximal end portions of brake arms to press a pair of pad assemblies against both sides of a brake rotor so as to hold it therebetween by means of a cam action of a wedge cam which is caused to move to a braking position along the direction of a rotational axis of a ball screw which is screwed into a ball nut which is provided integrally with the wedge cam as a result of the ball screw being driven to rotate. The wedge cam includes a compression coil spring for pushing to bias the ball nut towards the braking position where the proximal end portions of the brake arms are expanded and a spring holding mechanism for holding the compression coil spring in a biasing force accumulating state.
