Put the Electronic Parking Brake into Service Mode

Last updated: June 12, 2026

The Kia Niro (Mk1/DE, 2016–2022) — hybrid, plug-in and the e-Niro EV — uses a motor-on-caliper Electronic Parking Brake at the rear. There are no separate parking-brake pads: the EPB motor simply screws the rear piston out against the normal service pads. That means before you can renew those pads you must first reverse the motor into its pad-change state, and this guide explains how to do it correctly on the DE Niro.

Why the Mk1 Niro needs a tool for EPB service mode

Pull the EPB switch and a small motor on each rear caliper drives the piston outward to clamp the pads; that is the entire parking-brake mechanism on the DE Niro. To fit thicker new pads you have to run that motor backwards so the piston is fully retracted, then compress it the rest of the way.

Kia did not give the DE Niro an owner button sequence for this. There is no “ignition on, hold the switch” service mode on this car — the only sequence the dash offers owners is for wiper service position, not the brakes. The factory-correct method is a scan tool (Kia KDS or a capable aftermarket EPB tool) plugged into the OBD2 port, running the rear pad-change routine.

1. Park on level ground, chock the front wheels, switch the ignition ON (engine off / EV ready off), turn AUTO HOLD off and release the EPB.
2. Plug the scan tool into the OBD2 socket under the dash and select Niro / DE / EPB.
3. Run the Pad Replacement routine; the rear motors whir as they retract and the tool confirms the calipers are open.
4. Raise the car, remove the rear wheels, wind each piston in with a proper tool, and fit the new pads.
5. Reassemble, torque the caliper hardware, then exit service mode through the tool.

Critical warning: never force the EPB pistons back by hand or with a clamp. On the DE Niro the piston rides on the parking-brake spindle and must come back electronically. If you genuinely have no tool, the off-book workaround is to unplug the caliper motor and drive it backwards on a 12 volt supply (or unbolt the motor and wind the spindle with a Torx bit) — but you still must re-apply the EPB afterwards to re-tension it, and a clamp will simply strip the spindle.

Exit and bed-in: use the tool’s close-caliper step so the motors clamp onto the new pads, pump the brake pedal until firm, and cycle the EPB twice to confirm it sets and releases. Bed the pads with several gentle slow-downs from around 30–40 mph; on the hybrid and EV remember that regenerative braking masks pad feel, so make a few deliberate friction stops to seat them.

Frequently Asked Questions

Does the Niro EPB have its own pads? No — the EPB motor pushes on the regular rear service pads, so retracting it is essential before a pad change.

Is there a button-only service mode on the Mk1 Niro? No. The dash service sequence only covers the wiper position; the brakes need a scan tool on the OBD2 port.

Can I just clamp the piston in like an older car? No — that strips the spindle and can burn the motor. The piston must be retracted electronically.

Does regen braking change how I bed the pads? Yes — the hybrid and e-Niro use the motor to slow down, so make several normal-brake stops to bed the friction material in properly.

Will an EV-ready Niro need anything different? The EPB procedure is the same; just ensure the car is in the equivalent of ignition-on with drive disabled before connecting the tool.
