The Haldex Maxibrake R Series 3" 125 psi Pull Type Spring Brake is the perfect choice for heavy duty applications. This brake is designed with a steel casing for maximum durability and corrosion resistance. It features nylon bearings and a steel piston to help dampen lateral and twisting action. The epoxy-coated steel alloy springs offer outstanding resistance to rust and corrosion. In contrast, the deeper spring holes provide a longer lifespan and variable spring force. These push-rod threads make installation and maintenance a breeze. This brake will provide reliable performance in even the most challenging conditions. FleetPride is your First Click in Heavy Duty®.
