A disc brake includes a torque member rigidly mounted to an axle of a vehicle wheel. The torque member has arms protruding radially outward beyond the edge of the rotor. A caliper is mounted to the outer periphery of the torque member arms by pins extending through apertures within the caliper and the arms. The pins have a radially enlarged portion which slideably mount an outboard brake shoe. An inboard brake shoe is fitted between the two torque member arms and abuts the side edges of the arms. The caliper houses a piston which when actuated moves the inboard brake shoe into engagement with the rotor such that the caliper reaction portion urges the outboard brake shoe to press against the outboard side of the rotor. Torque stress from the brake shoes is transferred to the torque arms bypassing the caliper.

Caliper type disc brake

According to the present disclosure, a multi-stroke parking brake control has a pulley connected to a parking brake cable, a slidable actuating rod and connecting means constructed to drive the pulley when the rod is displaced. A gear is rotatably supported on the pulley and is in mesh engagement with a toothed rack formed on the rod. A one-way helical spring clutch drivingly interconnects the pulley and the gear in response to rotation of the gear caused by movement of the rod in a direction to tension the brake cable. A second one-way helical spring clutch interconnects the pulley and the housing and functions to hold the pulley in a brake applied condition. A release mechanism is arranged to release the second helical spring clutch to permit the pulley and cable to move to a released position under the force of a release spring. This construction of a parking brake control permits the actuating rod to be stroked a plurality of times to tension the brake cable as desired.
