Abstract
An improved and reusable stop assembly is provided for employment in drum brakes of the type having an internal lever operably coupled with the brake shoes for actuating the brake from a standby, partially retracted, relative position of the brake shoes to a position in which the shoes are spread apart to apply braking forces to the drum. The improved stop assembly includes a guide sleeve part mounted on the backing plate of the brake and a freely slideable and removable stop member receivable therewithin. When the stop member is inserted into and locked within the sleeve assembly, its inner end engages the lever to hold the shoes in their standby, partially retracted, relative positions against the forces of yieldably biasing means conventionally coupled with the shoes. The stop member may be released from the sleeve assembly by a simple manual rotation and withdrawal thereof to permit the shoes to shift into a fully retracted relative position facilitating maintenance operations, after which the stop member, which is reusable, may be reinserted into the sleeve assembly and relocked in position to hold the shoes in their standby, partially retracted, relative position by a simple manual reinsertion and rotation of the stop member.
