Caution! Do not attempt these procedures with disassembled brakes. Electronic Parking Brake (EPB) operations should only be performed with pads and calipers correctly installed. Follow these instructions precisely. Skipping steps may lead to unresolved issues. A full Auto-Scan with Vcds 18.9.1 is recommended to identify pre-existing faults before starting.
Opening Rear Parking Brakes with VCDS 18.9.1
Prerequisites:
- All rear brake components must be assembled.
- Connect a battery charger according to your vehicle’s repair manual.
- Cycle the parking brake ON and then OFF.
Procedure:
- Connect VCDS 18.9.1 to your vehicle’s OBD-II port.
- [Select] [53 – Parking Brake] [Basic Settings – 04]
- Choose “Start lining change mode” [Go!]. The calipers will open for pad replacement.
- Once “Finished Correctly” appears, click [Stop], [Done, Go Back], and [Close Controller, Go Back – 06].
- Turn off the ignition but keep the battery charger connected. Manually push the caliper pistons back in using a suitable tool. A flashing parking brake light is normal in this service mode. Do not operate the EPB switch or proceed until rear brakes are fully reassembled.
