What are Brake Discs and How do They Work?

There are two types of car brakes. One is called disc brakes while another called drum. If you are interested in buying disc brakes or want to do a brake disc replacement, then this is the right place for you!


Maybe you just want to know more about brake disc manufacturer, their components and how they work.


Simply defined, a disc brake is a type of brake that has calipers whose function is to squeeze a pair of brake pads against a rotor or disc. As they squeeze the brake pads, friction is created on the disc hence decelerate the rotation of the shaft. The end result is felt on the vehicle as it will eventually come to a stop.

Does my car have disc brakes?

All vehicles have disc brakes. For the front wheels it is the most preferred type of brake rotor.

This means that even if your car has drum brakes, they will only be on the back of the car wheels.

Otherwise, the front wheels will always have disc brakes.

This means that you should yearn to get significant info regarding disc brakes.

You may use the information later on when dealing with an issue with regards to your disc brakes.

In this article, we are going to highlight vital info regarding brake disc.

Chapter 1: What does a Disc Brake Do?

The answer to this question is very straightforward and simple.

A disc brake is designed to decelerate or even stop a vehicle from moving.

On the other hand, there are a lot of processes that are involved in allowing a disc brake to do its core mandate.

This is why you need to explore how a disc brake works.

How does a disc brake work?

The working principle of an auto brake disc is not difficult.

To understand how a disc brake works, here are the components that make up this braking system:


-Brake pads

-Automotive disc brake rotors

-A piston which is on the caliper

Now let’s look at how these different components work together to attain their mandate:

When you press the pedal of the brake, the brake fluid will push the piston outwards.

The piston will push the brake pads against the disc which is rotating.

The caliper will move inside forcing the brake pads to push extra outwards pressing the disc firmly.

A significant quantity of friction is produced between the brake pads and the rotating disc reduce the vehicle speed.

When you press the brake pedal continuously, the vehicle will finally come to a stop.

When you release the brake pedal, the brake pad will move away from the disc.

Chapter 2: What is the Difference between a Brake Rotor and a Brake Disc?

Is brake disc the same thing ad brake rotor?

No. Both are different objects.

This is despite the fact they are designed to perform the same thing.

A brake disc refers to the full assembly of the car’s brake system.

It includes of the brake pads, brake rotors, and caliper which holds the brake pads in position.

However, a brake rotor refers to the actual disc itself.

A brake rotor is a substantial flat circle disc that is connected to the car axle.

They rotors form the heart of the disc brake system since the brake pads get attached to them directly.

Perhaps you occasionally hear of the front disc brake rotor and back brake disc rotor.

Separately from the brake pads, it is also possible to do a brake disc replacement.
