Understanding Electric Parking Brake

The electric parking brake (EPB) is a modern feature in many vehicles that replaces the conventional handbrake lever. It is designed to provide better control, safety, and convenience. Understanding the electric parking brake and how it functions is crucial to addressing any issues that may arise with this system.

What Is An Electric Parking Brake?

An electric parking brake, as the name suggests, is a parking brake system that is electronically operated rather than mechanically. It eliminates the need for a handbrake lever by using an electronic control unit to apply the brakes.

How Does An Electric Parking Brake Work?

The electric parking brake system works by using an electric motor to apply the brakes. When engaged, the motor tightens the brake pads against the brake disc or drum, effectively holding the vehicle in place.
