Brake Rotors and Pads

What is a Brake Rotor?

A brake rotor is popularly known as a brake disc.  It is a shape or surface that is round and flat in appearance. As it is shown in the image below that fine flat surface is the disc. This rotor or disc spins with the wheel as the car moves forward and backward.

Function of a Disc

Brake rotors are necessary component in the braking system that stops the vehicle. Brake rotors are what the vehicle’s brake pads clamp down on to stop the wheels from spinning. Brake rotors are just as important to stopping the vehicle as the brake pads are.

In a disc brake system most vehicles have disc brakes only on the front wheels, though newer vehicles may have disc brakes on all four wheels.  A disc brake is a type of brake that uses calipers.  As it is shown above, the caliper is the one attached to the side of the disc. It is in the caliper that the brake pads are attached and the disc will be in between the pads. The caliper will squeeze the pair of pads against a disc or “rotor” to create friction.

How is it done? With disc brakes, the fluid from the master cylinder forces into a caliper where it presses against a piston. The piston squeezes two brake pads on a disc rotor attached to the wheel. This forces the wheel to slow down and stop

These pads are installed by pairs in the caliper. In between the pads is the brake disc.  When the inner pad is pushed by the piston both the pads will squeeze the disc to halt the car.

  1. How many breaks can it be caught with this Brake rotor?. The article provides a clear concept of brake rotors and pad. After that, I learned a lot of experience from this article. The author presented the matter beautifully. Highly recommendation from me and I am interested to use. Great article about Brake Rotors and Pads.

    • Thanks Jafor for leaving a comment. Your question is interesting, I never thought of that. My car is already forty years old but I never know a time the disc or rotor has been replaced. So it gives you all the breaks you wanted along your way. A break for snacks, a break to view scenery, or a break to have a rest.

      More of something to think about the pads because they easily wear than the disc.

  2. Used in almost all the automotive we have today this are essential parts of a vehicle when it comes to driving the break pad a steal plates that aids in friction of the brake when driving very crucial to a vehicle. Let not also leave the break rotors out of the gist as they are also has important as the break pads, that helps in bringing the vehicle to halt when commanded, working hand in hand the break pad holds on to the rotor to prevent wheel gyration . Both mechanism serve a great purpose as the other, a car is doomed without a break pad and likewise it’s also doomed if it does have a break pad but lacks the rotor , incisive post, Very informative. Couldn’t have been better very good job. 

    • Thank you, Dammy. I can see you understand about the disc brake system. Yes, the rotor is the one that is clamp by the pads in order to halt the car. 

      Since you are knowledgeable of disc brake system may I ask a question for us to engage our readers. Which is more often changed or replaced, is it the disc or the pads?
