Electric Parking Brake Actuator Drive Gear — BMW | 40 Teeth | OEM 34436782755
Fix Failed Electric Parking Brake on Your BMW — Replace the Actuator Drive Gear (40 Teeth).
The drive gear inside the BMW EPB (electric parking brake) actuator wears with use — causing the parking brake to stop engaging or releasing reliably. A new OEM actuator costs $200–$400+. This replacement gear (40 teeth) rebuilds the existing actuator at a fraction of that cost.
Why Replace Just the Gear
- Targeted Fix: The gear is the wear component — the actuator motor and housing are typically fine.
- Restores EPB Function: New gear restores correct actuator torque and reliable parking brake engagement.
