Electric Park Brake Actuator

A small electric motor and gearbox on each rear caliper that applies and releases the park brake, replacing the lever and cable entirely — and on most vehicles there is no mechanical override, so a failure means recovery rather than a workaround. The consequence that costs money is in servicing rather than in faults: the caliper piston is driven by the motor, so winding it back by hand to fit new pads destroys the actuator, and the module has to be put into a service mode with a scan tool first.

Also known as: epb, electric handbrake, electronic parking brake, park brake motor, caliper motor

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

Nothing posted about this yet. Whatever you found is worth writing down — even a dead end saves someone the same afternoon.

What makes one worth reading:

The car — make, model, year and engine. The same fault behaves differently on each.
What you measured, not only what you replaced.
What actually fixed it — or that nothing did, which is worth knowing too.
