Do so using the button inside the vehicle while applying the normal hydraulic brake pedal. When applicable the EPB must be cycled On and Off prior to the Function Test.It is important to wait 30 seconds after the brake calipers and live readings stop moving before clicking > prior to moving on to the next step.Click and the brake calipers will close after repairs. Refer to the specific Diagnostic Procedures page for the vehicle in question. Using VCDS you will click > and TYPE in the specific Group Number -or- Select the appropriate option from the drop-down menu.The EPB system service mode must be deactivated after the repairs.Perform the brake repairs and reassemble the system prior to moving on to the next step.

The caliper pistons do not move back into the caliper, they are in a internally released position that allows the technician to push the pistons in as you would do with a conventional front brake job.It is important to wait 30 seconds after the brake calipers and live readings stop moving before clicking > and removing the key from Ignition Switch.Click and the brake calipers will open for repairs. The specific Basic Setting groups vary depending on the vehicle and repair procedure to be performed. The EPB system must be put into a service mode prior to the calipers being removed from the vehicle so the pistons can be pushed into the caliper housing.The Parking Brake must be OFF prior to repairs or Basic Settings will not be possible!.Make sure the system is fully assembled prior to repairs! This includes the calipers properly installed on the rotors with pads and all electrical components being connected.This includes but is not limited to applying the normal hydraulic brake pedal and operating the EPB switch and running a complete Auto-Scan prior to repairs. Verify that the EPB system is working properly prior to the repair.Vehicles with a battery mounted in the rear typically use a battery management module and it is essential to connect the charger properly at the charging posts as shown in this: Audi A8 (4E) example.The EPB module is very sensitive to low voltage conditions! It is critical that a battery charger is properly connected and used for the duration of the rear brake job.Preparing the vehicle for the brake repairs 5.1 Electro-Mechanical Parking Brake (EPB), Rear Brake Service.1 Preparing the vehicle for the brake repairs.Replacing the brake pads on Electro-Mechanical Parking Brake (EPB) equipped vehicles consists of 4 main steps: VW Golf VII (5G/AU) (Rest of World MQB platform ABS).A8/S8 (4H) (4H vehicles use the Audi A6 (4G/4H) Parking Brake procedure).Audi Q3 (8U/FS) (older cars have 53, newer cars use the VW_Golf_VII_(5G/AU)_ABS_Brakes instructions).Vehicles that typically use the EPB system include: The specific procedures and Basic Setting groups for each vehicle are listed using the main Diagnostic Procedures page and choosing the proper Brand and Chassis type. This control module is accessed using address electronics. The following Tech Tip demonstrates the basic steps for working on the Electro-Mechanical Parking Brake (EPB) systems found in VW/Audi vehicles.
