How do disc brakes work in cars?

Brakes are a very important part of any vehicle. It is impossible to drive a car without brakes as brakes are essential for stopping a car. Most modern cars have disc brakes on front wheels and high-performance cars even have disc brakes on all four wheels. Here is a complete guide on how do disc brakes work in cars.

Working of disc brakes

The disc brakes work similarly to the brakes of a bicycle. The main components responsible for the working of disc brakes are brake pads, calipers and the hydraulic system. The working of the disc brakes is based on the pascal law.

  • When the brake pedal is pressed, high-pressure fluid from the master cylinder pushes the piston outward.
  • The piston pushes the brake pad against the rotating disc.
  • The inner brake pad touches rotor and the fluid pulls the outward brake pad towards the rotating disc.
  • Both the brake pads push the rotating disc which generates a lot of friction.
  • This helps in slowing down the vehicle and finally letting it stop.
  • When the brake pedal is released, the vehicle again starts to move.

Maintenance

Brake is like saving equipment in your car and maintaining them is very important. Due to the friction, the brake pads need maintenance otherwise the squealing or grinding noises can become apparent. You should get the brake pads checked periodically. Hearing any type of squealing sound when you press the brake means enough of the friction material is worn away and you should get it changed as soon as possible.

Today, due to the advances in improved manufacturing, disc brakes are much more reliable and effective. Not taking care of your disc brakes can be a terrible mistake. Follow the above guide to know how your car’s disc brakes work and get your brake pads changed when required.
