Claim:
A brake pad assembly, comprising: a backing plate fixed to a support plate; a pair of fastener openings having axes provided in said support plate for receiving an associated pair of fasteners for coupling said support plate to a support structure; a layer of friction material disposed on said backing plate; a mechanical interlocking portion disposed on said support plate having at least one retaining surface extending transverse to said axes of said fastener openings for providing redundant coupling support of said brake pad assembly to the support structure independent of said fasteners to limit movement of said brake pad assembly parallel to said axes of said fastener openings to maintain said brake pad assembly connected to the support structure in operation under a condition where said fasteners are disconnected from said brake pad assembly and the supper structure; and a knuckle body having a bridge extending laterally from said knuckle body, said bridge having at least a pair of openings for receiving said fasteners for coupling said brake pad assembly to said bridge, said bridge having a slot for receiving said mechanical interlocking portion and having an engaging surface for engaging said at least one retaining surface of said mechanical interlocking portion for limiting movement of said brake pad assembly relative to said bridge independent of and parallel to said fasteners.
