  Q: How to replace the power vacuum brake booster on Chevrolet Traverse?

  A:

  Park the vehicle on a flat spot and put the parking brake on before you began working. Before starting the replacement press and release the brake pedal until it becomes hard to use all the vacuum reserve. Take out the air filter assembly and the windshield washer solvents container from its compartment. Detach the master cylinder fluid level sensor electrical connection before removing the vacuum Brake Booster's check valve and hose units along with its vacuum sensor. Move the 2 brake pipes free from their routing clip on the frame rails. Then take off the bpmv valve's 2 nuts without disconnecting the pipes. Move the bpmv assembly forward when above the studs before removing its 2 master cylinder nuts yet keeping brake tubes connected. Set the master cylinder assembly on mechanics wire stands to maintain its upright position. Uninstall the left panel insulator and driver knee bolster from their places. Disconnect the brake pedal pushrod components by removing the clip and clevis pin. Take away the steering module and secure the 4 Brake Booster bolts. Shift the vacuum Brake Booster up and forward for the mounting studs to exit underneath the dash panel before you detach the vacuum Brake Booster. Check the vacuum Brake Booster gasket for damage against the dash panel and replace it when necessary. Thread the mounting studs of the vacuum Brake Booster onto the dash panel and fasten it with 4 nuts tightened to 25 nm (18 lb ft). Fit the intermediate Steering Shaft back in place and attach the brake pedal pushrod to its pedal base before setting the clevis pin with its retaining clip. Closely fit the driver knee bolster and left panel insulator so the master cylinder seal connects correctly with the vacuum Brake Booster while checking for damage. Check the Brake Master Cylinder seal connection to the vacuum booster unit and replace if detected damaged before installing both Brake Master Cylinder nuts at 20 nm torque. Carefully place the bpmv assembly over the studs while installing both bpmv nuts to their bracket. Tighten them to 20 nm (15 lb ft). Reattach the brake pipes through their path to the frame rail routing clip before reconnecting the master cylinder fluid level sensor power connection. You should attach the vacuum Brake Booster vacuum sensor and vacuum Brake Booster check valve and hose assembly to their proper positions on the vacuum Brake Booster. Put back the windshield washer solvent heater and the air cleaner unit last.
