The Haldex Maxibrake HR Series Spring Brake is a heavy duty corrosion-resistant brake. It has superior strength and excellent corrosion resistance. This brake features a steel casing for optimal durability and corrosion resistance, nylon bearings and a steel piston to assist with dampening lateral and twisting action. The epoxy-coated steel alloy springs offer outstanding resistance to rust and corrosion. In contrast, the deeper spring holes and larger piston diameter provide a longer lifespan and variable spring force. The unique design allows for easy installation and maintenance.
