2009 Ford Explorer Brake Booster Parts Q&A

• Q: How to service and repair the vacuum brake booster on 2009 Ford Explorer?

  A: Service and repair of the vacuum brake booster begins with disconnecting the brake booster check valve to let vacuum escape before taking off the master cylinder. Proceed to remove the brake master cylinder after disconnecting it. When removing the stoplamp switch it is necessary to have the brake pedal in the at-rest position with the plunger compressed inside the bracket so the switch can rotate properly or the switch could become damaged. The brake booster solenoid electrical connector needs to be disconnected until repairs finish because reconnecting it will prevent the creation of DTCs. The booster push rod clevis locking pin functions only once making it necessary to reject the used part and substitute it with a fresh unit whenever you remove it. Remove the brake booster rod linking the pedal to the brake and place it to the side. Toss out both the booster and brake booster nuts after discarding them before tightening new booster nuts to 22 Nm (16 lb-ft). The stoplamp switch should be installed while keeping the brake pedal stationary in its at-rest position and ensuring the booster push rod remains properly connected to the pedal. Proceed with the opposite steps of removal to install the component.
