Q: How to Change the Brake Booster Vacuum Hose on Buick Rendezvous?
A: Before working begin with the Brake Booster valve by removing the vacuum hose from the camshaft position sensor then unplug the vacuum Brake Booster check valve from its mount and take off the vacuum hose from the brake valve. To install this part use the vacuum hose to join the Intake Manifold then add the check valve to the Brake Booster before linking the hose unit to the valve.
