Brake Chambers

A-Line Chambers:
Engineered for High Torque, Long Life

A-Line service chambers and spring brakes are engineered for the rugged high heat and high torque environment found in air disc braking applications.
Inferior chamber design will result in premature failure of the chamber, inefficient braking performance, or complete loss of braking when you need it most.
So A-Line chamber products are built with seven critical features to ensure consistent braking and long life.   

7 Features Engineered For a Better Chamber

Air disc braking applications produce up to 15,000 ft-lbs of pressure with temperatures up to 1,500° F.
To ensure optimum performance, every chamber is built from OE-grade 11 gauge steel. Tempered grade 8 bolts are then welded with reinforcements into the casing. Inferior chambers use thinner steels and disfigure under pressure. They also only press in low yield bolts that shear under stress.
After coating each unit with a salt spray resistant e-coating, every chamber and spring brake is then sealed with a dust boot to prevent foreign matter from entering the caliper. A plastic boot guard ring reinforces the dust boot for longer life.
High tensile plungers are zinc coated for corrosion resistance and paired with polycarbonate spring stabilizers.
Thermal-resistant epoxy-coated springs and web-reinforced diaphragms are used to withstand extreme temperatures.
Finally, every A-Line service chamber and spring brake comes with a two-year full replacement guarantee.
