  Q: How to check and replace the Brake Booster Vacuum Hose and check valve on Buick Enclave?

  A: Before starting the process turn off the ignition and press the Brake Pedal several times until it becomes firm to drain the Brake Booster vacuum demand. Take out the windshield washer solvent heater part and disconnect the power vacuum Brake Booster check valve together with its attached hose from the Brake Booster. Begin by taking off the fuel injector sight shield and unfastening the vacuum hose routing clip off the intake manifold ball stud. Also disconnect the power vacuum Brake Booster hose from its location on the intake manifold vacuum port. Unplug the quick connect attachment from the power Brake Booster auxiliary supply pump and take out the vacuum Brake Booster hose assembly from the vehicle. Drill the vacuum Brake Booster hose and its clamp away from the check valve. Before installation put a small amount of denatured alcohol on the check valve male threads and fix the vacuum booster hose and clamp to this valve. Put the vacuum hose into place on the vehicle while connecting the power hose to the intake manifold vacuum port and adding alcohol if needed. Use the quick connect to connect power Brake Booster auxiliary pump then install the vacuum hose routing clip on the ball stud of the intake manifold and return the fuel injector sight shield to its appropriate place. Join the Brake Booster to the power vacuum check valve system and connect with denatured alcohol if needed. Install the windshield washer solvent heater if the vehicle has this component.
