ABSTRACT:
A force application system for a disc brake assembly in which twin pistons engage a configured load plate featuring stiffening ribs at specific locations to maximize the stiffness thereof seeking to provide uniformity of pressure transmitted therethrough to a friction pad. Additional uniformity of pressure is achieved by forming recesses in the backing plate of the friction pad proximate regions of pressure peaks. A singular recess at the point of pressure peak or recesses defined in a pattern identified by infinite element analysis may be utilized to optimize uniformity of pressure distribution.
