Midland Haldex MA15663 actuator is a MAXIBRAKE R-Series spring brake, air application, pull type, with 3.00 in. of available stroke, a #50 spring and a maximum air pressure of 125 PSI. It applies the service brake with air and holds a power spring for parking and emergency braking. The spring cannot be released by hand, so the vehicle stays put until the air supply recovers to a safe level. The steel housing resists corrosion, the aluminum piston rides on nylon bearings that keep the stroke steady against lateral and twisting loads, and the epoxy-coated steel alloy springs resist rust. A genuine Midland Haldex part from Pro Gear and Transmission. Call us to confirm proper fit.
A factory handling fee of $25.00 per order is added at checkout.
