Definitions:

S-cam Brake Systems

A type of drum brake system commonly used in heavy vehicles, where the rotation of an S-shaped camshaft forces brake shoes outward to create friction.

Air Disc Brakes

A type of brake system used in vehicles, particularly heavy-duty trucks and buses, that uses air pressure to push pads onto a disc to create friction and stop the vehicle.

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.
