Mechanical Braking Efficiencies

The effectiveness and performance efficiency of a mechanical braking system in converting kinetic energy into heat energy to stop a vehicle.

Drum Brakes

A brake system in which a rotating drum fixed to the wheel assembly turns around stationary friction-faced shoes. Braking action is achieved when the shoes are forced into the drum inside diameter. The common foundation brake system used on trucks using S-cam actuation of the shoes.

S-cam Type Foundation Brakes

A type of drum brake system commonly used in heavy vehicles, where an S-shaped cam forces the brake shoes apart and against the drum to create friction and stop the vehicle.

Axle Spindle

A component of the wheel assembly that provides a mounting point for the wheel and its bearing, allowing the wheel to rotate freely around the axle.
