Products Description
Camshaft Brake Roller
It is a key component in the vehicle braking system. In drum brakes, the camshaft brake roller is typically installed at one end of the brake shoe. When the brake is applied, the camshaft rotates, and its cam surface pushes the roller, causing the brake shoe to expand around the support pin. This brings the friction lining on the brake shoe into contact with the inner cylindrical surface of the rotating brake drum, generating a frictional resistance torque to achieve vehicle braking.
Despite its small size, it is critical to vehicle braking performance and safety. Wear, damage, or other issues may lead to brake failure or reduced braking efficiency, necessitating regular inspection and maintenance.
