Air Brake Chamber Diaphragm
Mack

The air brake chamber diaphragm is a key component in the air brake system, responsible for converting compressed air into mechanical force to apply the brakes. Its flexible design allows it to withstand high pressures and repeated flexing without failure, ensuring consistent brake operation. A high-quality diaphragm prevents air leaks, maintains proper brake chamber pressure, and contributes to the overall safety of the vehicle. Regular inspection for signs of wear or damage is essential to avoid brake failure and ensure optimal stopping power. Replacing worn diaphragms promptly can extend the lifespan of the entire brake chamber assembly.
