BRAKE ACTUATOR ASSEMBLY

A brake assembly wherein a reciprocable wedge actuator projects into an actuator housing containing two oppositely slidable brake shoe associated plungers disposed in aligned bores having a common axis and a fluid pressure motor unit has a tubular support by which it is mounted on the housing with the wedge actuator extending between a fluid pressure responsive element of said motor and the inner ends of said plungers, the housing having a bore into which the tubular support extends, flange means on the tubular support and on the housing concentric with the bore, one of the flange means comprising a plurality of circumferentially spaced lugs, and a split lock ring having means extending radially inward from each edge to engage the flange means and secure the tubular support to the housing.
