 What is a brakes?

A brake is a mechanical device that inhibits motion by absorbing energy from a moving system. It is used for slowing or stopping a moving vehicle, wheel, axle, or to prevent its motion, most often accomplished by means of friction.

Most brakes commonly use friction between two surfaces being compressed to convert the kinetic energy of the moving object into heat, although other methods of converting energy can be used. For example, regenerative braking converts much of the energy into electrical energy that can be stored for later use.

Other methods convert the kinetic energy in stored forms such as compressed air or pressurized oil into potential energy. Eddy current brakes use magnetic fields to convert kinetic energy into electrical current in the brakes disc, fin, or rail, which is converted into heat.

How brakes work on car?

To stop a car, the brakes have to get rid of that kinetic energy. They do so by using the force of friction to convert that kinetic energy into heat. This hydraulic system multiplies the force of your foot on the brake pedal into enough force to apply the brakes and make the car stop.

Brakes work by converting kinetic energy (forward motion) into thermal energy (heat). The friction between the stationary brake pad and rotating disk or drum as it slides past the pad converts the motion of the wheel and tire into heat, much the way rubbing your hands together on a cold day will warm them up.

Bringing your car to a stop generates enough heat at each wheel to boil a liter of water in about 7 seconds. Brake temperatures can reach around 500°F during normal everyday use and can reach up to 1000°F under heavy or repetitive braking.

What is brake system?

The brake system takes the kinetic energy of your moving vehicle and converts it to thermal energy through friction. Usually used for the back wheels (although some vehicles had four-wheel drum brakes years ago), drum brakes feature a hollow cylinder (the drum) attached to the axle that spins with the wheel.

The brake rotors are cleaned and dried by the brake pads dragging across them and the entire brake system is exposed to the air for efficient cooling. The advantages of rear drum brakes are lower cost and the ability to easily integrate a mechanical emergency/parking brake system.
