MGM Brakes' Remote-Mount Cylinders  are the original spring brake invented in the rugged logging country of Northern California.  These cylinders were introduced by MGM Brakes in 1956 as the world's first spring-actuated parking and emergency brake actuators for commercial vehicles.  The "pull-to-actuate" cylinders were designed for axle-mount or frame-mount using various weld-on and bolt-on mounting brackets and linkage arms.

Today, these high-quality air-actuated cylinders have been adapted to such diverse non-automotive usage as fail-safe dump truck end-gate actuators, emergency brake actuators on massive logging and commercial fishing winches, and numerous other special applications.

SAAR and SAHR Drive-line brakes were developed as replacement for manually operated lever applied "drive-line" brakes on class 6 and 7 vehicles. Mounted to the frame rail, the actuator utilizes a cable to apply parking force to a drum mounted on the drive-line. An optional electronic "travel" sensor provides the operator with information pertaining to the position of the push-rod, "applied" or "released".
