Air Brake Chamber Diaphragm
Volvo

The diaphragm within the air brake chamber is fundamental to the proper functioning of the braking system. It converts compressed air pressure into mechanical force, enabling the brake shoes to engage and slow or stop the vehicle. Made from flexible, durable materials, it must withstand high pressure and repetitive movement without failure. A compromised diaphragm can lead to reduced braking efficiency or complete brake failure, posing safety risks. Regular inspection and timely replacement are essential for maintaining brake performance. This component is critical for ensuring responsive and reliable braking in heavy-duty applications.
