Abstract
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.
