ABSTRACT:
A duo servo drum brake includes a pair of brake shoes which are movable by a hydraulic actuator during a service brake application to a braking position in engagement with a rotatable member. A strut and parking lever are engageable with respective brake shoes to separate the same during a parking brake application. In order to control a running clearance between the pair of brake shoes and the rotatable member, an extendible assembly is disposed between the pair of brake shoes opposite the hydraulic actuator. The extendible assembly is also responsive to a parking brake application to expand the pair of brake shoes into engagement with the rotatable member.
