VAG – Electro-mechanic Parking Brake System
VW/Audi Electro-mechanic Parking Brake (EPB) system integrates two
electro-mechanical actuators (Right and Left Parking Brake Motors) into the rear disc
brake callipers. The EPB system replaces the traditional handbrake system.
When the vehicle is stationary or when the EPB/Auto hold button is pressed the EPB
control module activates the parking bake motors on the rear wheels holding the
vehicle in place.
Pre-Test conditions:
• The vehicle must be stationary
• The vehicle must be on level ground
• The brake fluid level is correct
• The Parking brake is off
NOTE: During the process of releasing and resetting the brake pistons the ECM may
store DTCs in the EPB or ABS control modules. After completing the calibration
procedure the EPB and ABS DTC memory must be cleared.
