An electric parking brake, also known as an electronic parking brake or EPB, is a mechanism that automatically engages and disengages the vehicle's brakes to prevent it from moving. It uses an electric motor instead of mechanical components like cables and drums found in traditional parking brakes. The driver can activate and deactivate the electric parking brake by pressing a button or switch, which sends an electronic signal to engage the brakes. This type of parking brake is commonly found in modern vehicles for its convenience and ease of use.
