ABSTRACT:
A roller body for providing a brake shoe actuator, in a heavy-duty air brake assembly in which the braking effect is achieved by the movement of a cam which pushes on a brake shoe by rolling forcefully against the roller body which is revolvably carried by the brake shoe; and the roller body has a generally cylindrical surface which is provided with knurling grooves all running generally parallel to the axis of the body member, providing high torque and self-cleaning effect which gives smooth braking and extra gripping power by assuring smooth actuation of the brake shoe in response to the braking force applied to the cam shaft of the braking system.
