Frequently Asked Questions

Why does the parking brake actuator overheat?

The electric motor in the actuator generates heat during operation. If the brake is repeatedly applied and released in a short time, or if the brake is dragging, the motor can overheat.

Is a dragging parking brake dangerous?

Yes. A dragging brake generates excessive heat that can damage brake pads, rotors, and wheel bearings. It also reduces fuel economy and can cause brake fade.

How long does it take for the actuator to cool?

Typically 15-30 minutes of the vehicle sitting with the engine off is enough for the actuator to cool. The system should return to normal operation once the temperature drops.
