It connects to the vehicle’s air brake system where service and parking braking functions operate together. It combines a service chamber with a powerful internal spring assembly that activates during parking brake engagement. This long-stroke design allows the chamber to generate a strong mechanical braking force through the slack adjuster linkage. Whenever air pressure drops during parking brake activation, the Automann 179SB3030SLW225 converts spring force into braking pressure at the wheel end.
