MGM Improves Spring Brake Capabilities

The MGM Brakes Magnum Performance Plus series of piston-type spring brakes has an improved ability to handle space, weight, performance, safety, life expectancy, and quality requirements. Advantages of this series of actuators include:

• 3" (76-mm)-long stroke design ensures increased reserve stroke and greater safety.

• Patented "roll-in" tamper-resistant design prevents inadvertent disassembly of the power spring housing, while eliminating the large-outside-diameter flange.

• Patented dual-thread release bolt design offers minimal bolt protrusion at maximum release.

• New push-rod boot (for ball end adjuster disc brake applications only) seals the non-pressure chamber to the caliper upon installation with a two-lipped compression seal.

• Power spring has a corrosion protection coating of electrostatically applied and baked-on epoxy.

• External breather tube system prevents entry of liquid and airborne contaminants, allowing the exchange of only clean atmospheric air from the inside of the non-pressure chamber to the power spring chamber.

• Double protective coating on the head increases the actuator's impact and corrosion resistance.

• Compatible with S-cam, wedge, and air disc brake designs.

Current range of model variations: parking brakes from 1,550 to 2,600 pounds of push-rod braking force (at 1.25" stroke); service brakes in sizes 20, 24, 30, and 36.
