What does BSFB mean in FOUNDATIONS

The Bendix Spicer Foundation Brake (BSFB) is an air-actuated drum brake specifically designed for heavy-duty commercial vehicles such as trucks and buses. It consists of a primary power chamber and a spring chamber which use air pressure to move the brake shoes away from the drums for a smooth application.

The BSFB uses compressed air from the truck's on-board air brakes to actuate a power chamber located behind each wheel. This causes one or more brake shoes to press against the inside surface of each drum which slows down or stops rotation of that wheel.

Yes, it is important to regularly inspect and service your BSFB system to ensure it provides optimum performance when braking. Maintenance tasks typically include inspecting brake linings for wear, checking air pressure levels, cleaning drums and adjusting clutch springs where applicable.

The primary benefit is improved brake control over long distances with limited driver fatigue. The BSFB also helps reduce stopping time due to its fast response time and offers enhanced vehicle stability when slowing down or stopping.

All installation, repair and maintenance must be completed by trained professionals who specialize in trucking applications such as those found at repair facilities authorized by major truck manufacturers like Freightliner, Peterbilt, etc.
