ABSTRACT:
A vehicle brake unit having a fluid pressure operated piston arranged perpendicular to a brake push rod on which is provided a pair of diagonally opposed roller members. An actuator member is connected to the piston and is interposed between the piston and push rod to translate the force of the piston to the push rod. A thrust surface having a cam profile is engageable with the roller members of the push rod, while a reaction surface is engageable with the brake unit housing. The actuator reaction surface is convex and the complementary thrust surface of the housing is concave, thereby providing a pivot point about which the actuator is angularly rotated when the piston is operated to establish a brake stroke of the brake push rod.
