The North American commercial vehicle industry has been steadily transitioning to the use of Air Disc Brakes (ADB) for many years and the presence of ADB systems in virtually every market segment certainly cannot be ignored. While traditional S-Cam air brake systems have been reliable and effective in many ways, there are distinct advantages of Air Disc Brakes over S-Cam.
Commercial vehicle air brake systems require optimal performance from all components to ensure safe and reliable operation. Typical heavy duty applications use Type 30/30 standard stroke double diaphragm actuators for service and parking brake functions. Type 30/36 long stroke actuators offer unique advantages for heavy duty drum brake applications.
