Brake systems on vehicles are typically driven by either pneumatic or hydraulic systems that multiply the force applied by an operator to slow a vehicles rate of speed through the use of friction.
Brake system components
There are different types of brakes systems used in vehicles.

Brake Rotor and Caliper
A brake rotor spins on an axis attached to a shaft. A caliper straddles a brake rotor and clamps the rotor with brake pads. Brake pads actuated by the caliper hydraulically squeeze the rotor through pneumatic or hydraulic force to apply friction and slow the vehicle.
