How Does The Brake System Work?

If you have ever wondered how the brake system works, you are in the right place! Below, you will find a simple and easy-to-understand explanation of how the system works by dissecting its main components and explaining what role they play. Keep in mind that any problem in one of these parts can cause issues and take a toll on your overall safety. Here are the main steps the braking system goes through when you press the brake pedal.

Step 1: Brake Pedal

The first step of the process is the brake pedal. It's located in the footwell of the driver's side and is either the second (in manual cars) or the left (in automatics). It can be either electric or hydraulic, depending on the make and model of the car. The main thing that it does is convert the driver's input into a signal through the brake lines or wires.

Step 2: Brake Lines

The brake lines connect the brake pedal and calipers. The input from the brake pedal pressurizes and moves the liquid that is in the lines, causing the activation of the calipers.

Step 3: Calipers 

Calipers can be found on either one set of wheels or on all four - additionally, there can be more than one caliper per wheel. When the fluid in the brake lines moves, a sensor detects the change and starts to move the pistons (located in the caliper). The number of pistons differs depending on the car, but most commonly they are four - the more pistons, the greater the stopping force.

Step 4: Brake Pads And Rotors

The brake pads are in the calipers, and the rotors are mounted on all wheels that have a caliper. When the pistons are activated, the brake pads come in contact with the rotors, resulting in the deceleration of the vehicle. These two components are some of the most used and frequently changed in the car, so make sure to keep an eye on them.
