What is a Parking Brake?
A parking brake, also known as an emergency brake or handbrake, is a mechanism designed to prevent a vehicle from moving when it’s stationary. It’s typically engaged when the vehicle is parked on an incline or when the driver needs to exit the vehicle temporarily. The parking brake works by applying pressure to the wheels, usually through a system of cables, levers, and drums, to prevent the vehicle from rolling or moving.
Types of Parking Brakes
There are two primary types of parking brakes: mechanical and electronic.
Mechanical Parking Brake: This type of parking brake uses a mechanical linkage to apply pressure to the wheels. It’s typically operated by a lever or pedal located near the driver’s seat.
Electronic Parking Brake (EPB):b This type of parking brake uses electronic sensors and motors to apply pressure to the wheels. It’s often operated by a button or switch located on the center console. (See Also: How to Use Duralast Deluxe One Man Brake Bleeder Kit? Effortless Brake Bleeding)
