Brake caliper servo motor fits MERCEDES C63 AMG 4.0 Rear Left or Right 14 to 23

About this deal

This is a replacement brake caliper servo motor for the Mercedes C63 AMG 4.0 (W205 platform), covering model years 2014 to 2023, and fitting either the rear left or rear right caliper. The electronic parking brake (EPB) uses electric motors to apply the brake pads or calipers to the rear wheels, achieving the same function as a traditional handbrake but done electronically. The brake pads are applied via an actuator mechanism controlled by an electronic control unit (ECU), which can also automatically release the EPB when the driver starts the engine or puts the vehicle in gear. Common causes of parking brake actuator failure include water infiltration, corrosion or rust causing mechanical damage to the motor or gears, internal electrical issues, prolonged inactivity, and frequent improper operation. Telltale signs of a faulty motor include the parking brake failing to engage when the button is pressed, or a loud screeching noise when attempting to apply or release the brake. This part is suited to owners and mechanics looking to restore full EPB function without replacing the entire caliper assembly.
