How do the brakes on your car work?

How Car Brakes Work

When you press down on the brake pedal in your car, a series of events takes place that ultimately result in the vehicle slowing down or coming to a stop. Here's a step-by-step explanation of how the brakes work:

1. You press the brake pedal.

This is the action that starts the braking process. When you push down on the pedal, you are actuating a piston in the master cylinder.

2. The master cylinder generates hydraulic pressure.

As the piston in the master cylinder moves, it compresses the brake fluid in the cylinder. This creates hydraulic pressure, which is transmitted through the brake lines.

3. The brake fluid travels through the brake lines.

The brake fluid, under pressure, travels through the brake lines to the calipers at each wheel.

4. The calipers engage the brake pads.

Once the brake fluid reaches the calipers, it pushes on a piston in each caliper. This causes the brake pads to be forced against the brake rotors, which are metal discs attached to the wheels.

5. Friction between the brake pads and rotors slows down or stops the vehicle.

As the brake pads press against the brake rotors, friction is created between the two surfaces. This friction converts the kinetic energy of the vehicle into heat and slows down the rotation of the wheels. As a result, the vehicle will decelerate or come to a stop.

It's important to note that while the basic principles of braking are the same across most vehicles, some cars may have additional features or components, such as anti-lock braking systems (ABS), to enhance braking performance and safety.
