Put the Electronic Parking Brake into Service Mode

Last updated: June 12, 2026

The Opel Zafira Tourer (C/P12, 2011–2019) was offered with an electronic parking brake (EPB) on higher trims and option packs, operated by a switch near the gear selector rather than a lever. If your Zafira has that switch, the rear calipers have to be drawn back into a maintenance position before new pads will fit. This GM-era car has a genuine owner-operated service mode, so for a basic rear pad change you do not need a dealer scan tool — you just have to follow the ignition-and-switch sequence exactly.

Putting the EPB into service mode for a rear pad change

First, check which parking brake you actually have. Many base and mid Zafira Tourer C cars left the factory with a conventional manual handbrake lever; this procedure only applies to cars with the EPB switch. If you have a lever, the calipers are not motorised and this guide does not apply.

For EPB-equipped cars, service mode winds the rear caliper motors fully back and stops the brake re-clamping with the wheel off. Do it before you touch the pads.

1. Park on level ground, chock the front wheels and put the transmission in neutral (or P on an automatic) with the engine switched off.
2. Turn the ignition ON but do not start the engine.
3. Press the brake pedal firmly several times to bleed off the brake-booster vacuum.
4. Keep the brake pedal pressed, then press and hold the EPB switch until the orange parking-brake warning lamp begins to flash.
5. Still holding the pedal, release the switch and press it again for roughly 5 seconds.
6. Release the brake pedal. The orange lamp goes out briefly, then the rear caliper motors retract. The calipers are now in service mode.

Now lift the car, remove the rear wheels and replace the pads.

Critical: never force the pistons back by hand

The EPB caliper piston on the Zafira Tourer is driven by an internal spindle motor. Never push the piston in with a clamp, and never use a wind-back tool. The service-mode sequence retracts the motor electronically to the right position; forcing it mechanically strips the spindle or shears the actuator, which means a replacement caliper. On this car the piston is pushed back electronically only — not wound by hand.

Exiting service mode and bedding in

With the new pads in and the wheels refitted:

1. Transmission in neutral/P, ignition ON, engine off.
2. Press and hold the brake pedal, then pull the EPB switch up until the orange lamp goes out and the rear calipers extend back to their clamp position.
3. Release the brake pedal.

Start the engine and apply/release the parking brake two or three times, checking the warning lamp behaves normally. Then bed the pads in: make 8–10 gentle stops from about 30–40 mph with cooling gaps between them, and avoid hard braking for the first 100–200 miles so the friction material transfers evenly.

Frequently Asked Questions

Does my Zafira Tourer have an electronic parking brake? Not necessarily — the EPB was a higher-trim and option-pack feature. Look for a small switch marked “P” near the gear lever. If you have a pull-up handbrake lever instead, your car has a conventional cable handbrake and this procedure doesn’t apply.

Can I change the rear pads without a scan tool? Yes, if the car has the EPB and it’s fault-free. The owner service-mode sequence on the Zafira Tourer C means a basic pad change needs no diagnostic scanner.

The lamp won’t flash when I press the switch. Usually the booster vacuum hasn’t been bled off or the ignition is in the wrong position. Confirm engine OFF, ignition ON, pump the pedal several times, then try the press-and-hold again.

Do I need to bleed the brakes afterwards? No — a pad-only change doesn’t open the hydraulic circuit. Just check the fluid reservoir level after refitting and top up to MAX if needed.

The EPB warning light stays on after the job. That normally means service mode wasn’t fully exited or the calipers didn’t re-clamp. Repeat the exit sequence; if the light persists, scan for EPB fault codes before driving.

If a warning light or stored fault code appears during the job, you can look up what it means on autodtcs.com.
