Most modern vehicle braking systems combine leverage with multiplied hydraulic force to stop the vehicle. When the driver pushes down on the brake pedal, fluid that is under pressure is sent to the brake assembly at each wheel. Then the fluid forces a stationary part, the brake pads or brake shoes, against a rotating part, the brake rotors, or brake drums. Most vehicles have an antilock brake system (ABS) that prevents the wheels from locking up during braking and some vehicles with ABS have a traction control system that prevents wheel spin and improves the tires contact with the road.
While most manufacturer factory warranties only cover the brake system for a short period of times, there are some extended auto warranties available that will extend braking system coverage after the manufacturer factory warranty has expired.
