Trailer axles with S-cam brakes are the use case for the Bendix Air Brake Spring Brake, which provides service and parking braking from one assembly. On trailers, the spring brakes also apply automatically if the trailer breaks away and loses air supply. The Bendix K153451 goes on as a complete unit and is never opened, the only safe approach when the housing or diaphragm fails. Setting push-rod length after installation keeps the stroke within limits across the axle.
