Abstract
A dual mode drum brake assembly having an improved duo-servo parking and emergency brake lever mechanism includes a pivot lever pivotally supported relative to a first brake shoe and operatively coupled to exert an outward force on the first brake shoe when the parking brake is actuated. According to one feature of the invention, a hold down assembly extends through an aperture formed in a web of the first brake shoe, and through an aperture formed in the pivot lever to secure the first brake shoe to a backing plate and to pivotally connect the pivot lever to the web. According to another feature of the invention, an adjuster lever of a first strut member is pivotally supported on the first brake shoe, and the pivot lever is pivotally supported on the first brake shoe generally intermediate the first strut member and a second strut member.
