Abstract
To reduce the brake-application travel necessary for brake shoe actuation, to reduce the brake fluid volume consumption of the brake-shoe-actuating member in a hydraulic brake, to reduce the brake pedal travel required for a braking operation and to improve the efficiency of a floating caliper disc brake, there is inserted a spreading device between the brake-shoe actuating device and the brake pad connecting the circumferential travel of the brake pad caused by engagement with the brake disc into an axial displacement increasing the axial distance between the brake-shoe actuating device and the brake shoe, when the spreading device is moved out of its spring-biased central position into engagement with a supporting surface at the brake housing.
Claims15
A spot-type disc brake comprising:
- at least one brake-shoe-actuating member axially slidably disposed in a brake caliper and adapted to be acted upon by a brake force;
- a supporting surface disposed in said actuating member to receive a circumferential force acting upon a first brake shoe actuated by said actuating member when said first brake shoe engages an adjacent surface of a brake disc during a braking operation, said first brake shoe being spaced a given distance from said support surface in a brake release position;
- and
- an expanding device disposed between said first brake shoe and said actuating member which upon movement of said expanding device towards said supporting surface urges said actuating member a predetermined amount away from said first brake shoe.
