Air brake maintenance products support the repair of compressed air braking systems that are primarily used by trucks hauling heavy loads. Air brakes are the chamber mechanisms for generating compressed air. Air brake hose and cable supports extend the operating life of air brake lines by preventing them from hanging loose and dangling where they can get damaged during transporting and hauling operations. Air brake slack adjusters maintain consistent brake chamber stroke and clearance by reducing the slack that can be caused by surfaces wearing over time due to friction.
