Abstract:
1. A disc brake assembly comprising: an anchor bracket adapted to be secured to a vehicle component; a brake caliper adapted to be secured to said anchor bracket; an inboard friction pad and an outboard friction pad carried by said disc brake assembly and adapted to be disposed on opposite axial sides of an associated brake rotor; actuation means for selectively moving said inboard and outboard friction pads into frictional engagement with the rotor; and a pad spring carried by at least one end of one of said friction pads for moving said friction pads from engagement with the rotor when said actuation means is released; wherein said pad spring includes a generally U shaped portion having a first tab and a second tab, said first tab having a first remote end defining a first remote end width for applying a first retraction force and said second tab having a second remote end defining a second remote end width which is different from said first remote end width for applying a second retraction force which is different from said first retraction force thereby providing an asymmetrical friction pad retraction feature.
