A braking system for a railway truck including a pair of brake assemblies, each adapted to brake the wheels on opposite sides of the truck. Each of the brake assemblies includes a pair of crank members pivoted on the truck with brake shoes to engage the wheels, a drive link with one end connected directly to one of the crank members and the other end connected to the other crank member through a motion reversing linkage, and a brake cylinder with a reciprocal brake rod pivotally connected to the drive link equidistant from its ends so that equal braking forces are applied to the wheels as the brake rod moves the drive link to pivot the crank members in opposite directions. A hand brake connection assembly is also disclosed to allow the crank members to be manually pivoted to brake the wheels.
