There is disclosed a spot-type disc brake having a brake carrier protruding over the brake disc and brake shoes on each side of the disc, one shoe being directly actuated by a hydraulically actuated piston and the other shoe being actuated by a brake caliper embracing the disc. A sliding guide is provided to connect the caliper to the carrier so that the caliper is movable relative to the carrier towards and away from the disc. The sliding guide includes guide portions having grooves in the caliper and projections in the carrier to engage the grooves. An opening is provided in the caliper so that the brake shoe adjacent the actuating device can be removed without disassembling the caliper from the carrier. The guide portions have a limited length so that when the caliper is shifted into the space left by the removed brake shoe, the guide portions can be disengaged. This arrangement provides a positive arrangement to prevent the caliper and carrier from separating during operation without additional components in the guide portions as is present in similar prior art disc brakes. |
