Truck Brake Parts Heavy Duty Disc Kits for Disc Brake Assembly

The thermal expansion of the brake disc along the thickness direction is very small, which will not increase the brake clearance significantly as the brake drum does, resulting in excessive brake pedal travel; It is easy to realize automatic clearance adjustment, and other maintenance and repair operations are relatively simple.

The design of the brake discs is somewhat different. Some are solid, but others are hollowed out by connecting the two contact surfaces of the valve disc with fins or blades (usually as part of the casting process). The weight and power of the vehicle determine the need for the ventilation panel. "Vented" brake discs are designed to help dissipate heat and are typically used on heavily loaded front brake discs.
