Electronic Parking Brake
An electronic parking brake uses electric motors, operated by a switch, to hold the car instead of a hand lever and cable.
What is Electronic Parking Brake?
The motors usually sit on the rear calipers. Some systems use a central motor pulling cables. It often has an auto-hold function and releases automatically when you drive off. Because the system is controlled electronically, it can also act as an emergency brake when the switch is held while driving, using the main brakes through the stability control unit.
How it works
The control unit drives the motors to clamp the pads and checks the force.
Why it matters for your car
Replacing the rear pads requires a service mode or a diagnostic tool to retract the pistons. If the battery is flat the brake may not release; the owner's manual describes the emergency release procedure for your car.
