4 Types of Car Brakes
Disc brakes consist of a brake rotor which is attached directly to the wheel. Hydraulic pressure from the master cylinder causes a caliper (which holds the brake pads just outside the rotor) to squeeze the brake pads on either side of the rotor. The friction between the pads and the rotor causes the vehicle to slow and stop.
Drum brakes consist of a brake drum attached to the inside of the wheel. When the brake pedal contracts, hydraulic pressure presses two brake shoes against the brake drum. This creates friction and causes the vehicle to slow and stop.
Emergency brakes, also known as parking brakes, are a secondary braking system that work independent of the service brakes. While there are many different kinds of emergency brakes (a stick lever between the driver and passenger, a third pedal, a push button or handle near the steering column, etc.), almost all emergency brakes powered by cables which mechanically apply pressure to the wheels. They are generally used to keep a vehicle stationary while parked, but can also be used in emergency situations if the stationary brakes fail.
Anti-lock braking systems (ABS) are found on most newer vehicles. If the stationary brakes are applied suddenly, ABS prevent the wheels from locking up in order to keep the tires from skidding. This feature is especially useful when driving on wet and slippery roads.
