This is an electric parking brake actuator motor, the small geared electric motor unit housed within the rear caliper assembly that winds and releases the parking brake cable on vehicles equipped with an electronic (button-operated) handbrake. It replaces a failed or seized motor-reducer unit that commonly causes an electric parking brake fault message, an inoperative handbrake, or a caliper that will not release, and is manufactured from high-quality materials with in-house testing before shipping as a cost-effective alternative to buying a complete caliper assembly.
Fitment: BMW X5 (E70) and X6 (E71), covering the electronic parking brake actuator motor used across these chassis, cross-referencing OE numbers such as 34436850289, 34436785487 and 34436796072.
