Antilock Brakes
An antilock braking system (ABS) minimizes wheel lockup (skidding) by using sensors at each wheel (or in the differential) to monitor wheel speed, a hydraulic unit to regulate brake pressure, and a computer/controller to command the system.

Parking Brakes
A hand lever in the center of the console or small foot pedal on the far left side of the driver’s foot controls engages the cable.
The mechanical cable allows the systems to work independently of each other.

Summary
Brake systems use friction to slow and stop a vehicle.
The two types of brake systems used today are disc and drum brakes.
Disc brakes use rotors, pads, and calipers.
Drum brakes use drums, shoes, and wheel cylinders.
Antilock brakes assist in preventing wheel lockup and provide the operator with maximum directional control.
