Abstract
A brake slack adjuster with axially aligned, first and second load members connectible at their free ends, respectively, to the brake rigging and a lever operable by the piston of the brake cylinder. First and second brakes act between the load members. The second load member is movable axially with respect to the first brakes which, in first relative positions thereof, permits axial movement of the load members relative to each other and which, in second relative positions thereof, prevents relative axial movement of the load members. The second brake is movable relative to the second load member and prevents relative movement of the load members until the braking force exceeds a value, such as 1000 pounds. The second brake is releasable by a spring loaded, axially movable actuator so that the second load member can move axially to its second position and cause actuation of the first brake.
