Put the Electronic Parking Brake into Service Mode

Last updated: June 11, 2026

The Bentley Continental GT (Mk2, 3W, 2011–2017) shares its Volkswagen-group D-platform underpinnings with the contemporary Audi A8 and VW Phaeton, and with them it uses a motor-on-caliper electronic parking brake: an electric actuator bolted to each rear caliper. Changing the rear pads means putting the EPB into service mode with a diagnostic tool first — there is no owner button sequence that retracts the calipers, and the parking-brake module is easy to damage if you get it wrong.

What service mode is and why the 3W needs it

Each rear caliper carries an electric actuator that clamps the piston for parking. With the car live, that actuator holds the piston in place. Service mode commands both rear motors to retract (open) and locks the EPB out so it cannot re-apply while your hands are at the caliper. On the Continental this is done through the parking-brake module (address 53) with VCDS, ODIS or a capable VAG-protocol OBD tool — the dash has no menu for it.

Retracting the rear calipers on the Continental GT

Park level, chock the fronts and connect a battery charger — the parking-brake module can be bricked if voltage drops mid-routine, so this is not optional on a Bentley.

1. Release the EPB. In the tool, open [53 — Parking Brake] → Basic Settings and run the retract / open routine (VCDS code 007). Both rear actuators wind back.
2. Unbolt and remove the calipers. The pistons on this caliper do not wind in — once the actuator has retracted, push each piston straight back with a C-clamp the conventional way.
3. Fit the new pads and refit the calipers.

Never force the EPB pistons back by hand

Never push the rear pistons back before the actuator has been retracted in service mode. Forcing a piston against a clamped EPB motor loads and can strip its gearset, writing off a costly caliper. Only after the basic-settings retract has run is it safe to compress the piston straight in. And only cycle, open, close or function-test the EPB with the pads and calipers properly fitted to the rotors — never with a caliper hanging off.

Exit, calibration and bed-in

With the new pads and calipers fitted, run the EPB close routine (VCDS code 006) so the actuators re-clamp, then update the pad-thickness adaptation (channel 06, enter the new pad thickness in mm) and run the parking-brake function test. Cycle the ignition, apply and release the EPB a couple of times and confirm the warning light is out. Then bed the pads in with several firm slowdowns from about 40 mph, cooling between, and check the parking brake holds on a slope.

Frequently Asked Questions

Do the Continental’s rear pistons wind in or push straight? They push straight. The actuator retracts electronically in basic settings; the piston itself is then compressed with a C-clamp, it does not rotate.

Can I do it without VCDS? You need a VAG-capable tool (VCDS, ODIS or equivalent) for the retract, pad-thickness and function-test steps. A generic reader that only clears codes won’t do.

Why is the battery charger so important here? A voltage drop during an EPB session can corrupt the parking-brake module and require replacement. Keep a charger on throughout.

Do I have to enter the new pad thickness? Yes — the module tracks wear by pad thickness, so updating the adaptation keeps the wear warning accurate.

The EPB faulted during the job — why? Usually low voltage or a routine run with a caliper off the rotor. Charge the battery, refit everything, re-run and clear the code.
