ABSTRACT:
A wedge-type actuator for actuating drum brakes including guide rollers positioned between the wedge and a plunger that contacts the leading brake shoe. The guide rollers are carried between a guiding surface on the wedge and a guiding surface in the housing, to take up the reaction forces caused by the larger actuation forces needed to operate the trailing brake shoe. The disclosed arrangement provides more even braking forces, and thereby results in more even brake shoe wear.
