An improved car mounted brake assembly is provided wherein the brake assembly includes a brake cylinder, a slack adjuster and a pair of brake beams mounted at each end of the car mounted brake assembly and actuated by the brake cylinder via a series of levers and linkages and wherein the improvement comprises a suspension system for suspending each of the brake beams within a corresponding railway vehicle truck arrangement. Each of the brake beams have a brake head attachable to each end thereof and each of the brake heads carries a brake shoe thereon which is positioned for engagement with a respective railway vehicle wheel during a brake application. The railway vehicle truck arrangement within which the brake beams are suspended includes a pair of truck side frames and a truck bolster member. The suspension system comprises a first device pivotally connected at a first end thereof with a predetermined portion of the railway vehicle truck arrangement and pivotally connected at a second end thereof to a predetermined portion of the car mounted brake assembly for suspending the pair of brake beams in the railway vehicle truck arrangement. The suspension system also includes a second device having at least a portion thereof connected with the car mounted brake assembly for maintaining each of the brake beams in a predetermined plane during application and release of the railway vehicle brake assembly.
