Put the Electronic Parking Brake into Service Mode

Last updated: June 11, 2026

The Bentley Continental GT (Mk3, 3S, 2018–2022) moved onto the Volkswagen-group MSB platform shared with the Porsche Panamera, but it keeps a motor-on-caliper electronic parking brake — an electric actuator on each rear caliper. A rear-pad change therefore starts by putting the EPB into service mode with a VAG-protocol tool; there is no owner button sequence, and the parking-brake module must be handled carefully to avoid an expensive mistake.

What service mode is and why the 3S needs it

Each rear caliper has an electric actuator that clamps the piston for parking. Service mode commands both rear motors to retract (open) and locks the EPB out while you work. On the third-generation Continental this runs through the parking-brake module (address 53) with VCDS, ODIS or a capable VAG OBD tool. There is no dash-menu shortcut.

Retracting the rear calipers on the Continental GT

Park level, chock the fronts and connect a battery charger — voltage drop during an EPB session can brick the module, so a charger is mandatory on this car.

1. Release the EPB. Open [53 — Parking Brake] → Basic Settings and run the retract / open routine (code 007). Both rear actuators wind back.
2. Unbolt the calipers. The pistons do not screw in — once the actuator is retracted, push each piston straight back with a C-clamp.
3. Fit the new pads and refit the calipers, then run the close routine (code 006) so the actuators re-clamp.

Never force the EPB pistons back by hand

Never push a rear piston back until the actuator has been retracted in service mode. Forcing a piston against a still-clamped EPB motor strips its gearset and ruins the caliper — not a cheap part on a Continental. Compress the piston straight in only after the basic-settings retract has run. And only open, close or function-test the EPB with pads and calipers properly fitted to the rotors, never with a caliper hanging loose.

Exit, calibration and bed-in

After the close routine, update the pad-thickness adaptation (channel 06, enter the new pad thickness in mm) so the wear monitor stays accurate, then 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. Bed the pads in with several firm slowdowns from about 40 mph, cooling between. Continental GT models fitted with the optional carbon-ceramic (CSiC) brakes do not need a pad grind-in, but the ceramic discs are fragile and very costly, so handle them with care.

Frequently Asked Questions

Do the rear pistons wind in or push straight? Push straight. The actuator retracts electronically; the piston is then compressed with a C-clamp and does not rotate.

Can I do this without a VAG tool? No — you need VCDS, ODIS or an equivalent for the retract, pad-thickness and function-test steps. A basic code reader will not perform them.

Why is a battery charger essential? A voltage dip during an EPB basic-settings session can corrupt the parking-brake module and force a replacement. Keep a charger connected throughout.

Anything different with the carbon-ceramic brakes? The ceramic pads skip the grind-in and the discs need gentle handling, but the EPB retract / close / adaptation steps are the same.

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