VehicleBrake
A VehicleController which is capable of stopping the motion of a Vehicle.
Relationships      
Parents Brake Any device that is designed to slow and stop the Motion of an object. This include brakes on wheeled vehicles as well as rock climbing equipment that uses friction to slow decent when rappelling.
  VehicleController Any Device which is used to start, stop or control the movements of a Vehicle. This class covers steering wheels, brakes, acceleration pedals, airplane sticks, etc.
Children AntilockBrakeA VehicleBrake with an electronic component that reduces the likelihood of locking up the wheels during a sudden stop. If the wheels stop turning, the controller reduces pressure on the brakes until they begin turning again, then alternates application and reduction of braking pressure in short intervals. The goal is to keep the wheels at as near as possible the point of transition between dynamic or sliding friction and the point of static friction (at which the stopping force is greater).
 DiscBrake
 DrumBrakeA Brake in which a BrakeShoe presses against a rotating BrakeDrum to cause vehicle braking.
 ParkingBrakeA kind of brake chiefly designed to prevent motion from occuring in a stopped vehicle, although it can be used to slow a vehicle that is in motion. Most other types of brakes are designed to be used intermittently to slow a vehicle, or only temporarily to keep a vehicle stationary, while the driver is applying the brake. In contrast, most parking brakes employ some sort of ratcheting system so the parking brake may remain active even when the driver is not applying force to a braking actuator, or even being present in the vehicle. Typically, it is implemented as a DrumBrake in most modern passenger vehicles.
