• Q: How to replace the vacuum brake booster on 2001 Buick Century?

  A: Always make sure that the cruise control cable is not squeezed between the booster and the cowl before replacing the vacuum Brake Booster. First, take out the left instrument panel insulator; after that, disconnect the stoplamp switch electrical connector. Pull off the retaining clip and take off the Brake Booster pushrod from the Brake Pedal. Release a little coolant from the system, remove the cross vehicle brace, and take out the air cleaner inlet duct. Once the fuel system pressure is gone, take off the evap canister purge valve pipe, fuel feed pipe, and return pipe and put them aside. Take off the coolant bypass hoses, and take the heater inlet pipe out. Swivel the engine ahead to access the area, and then pull out the brake fluid level sensor's connector. You don't need to take off the brake pipes from the master cylinder to the bpmv. Take off both the retaining nuts for the master cylinder and keep it separate. Take off the vacuum Brake Booster check valve from the Brake Booster and keep the hose with the check valve attached so they do not get separated. Failing to do so will cause the Brake Booster to slide out instead of rotating off the power Brake Booster holder (J 22805-B When installing, put the Brake Booster on the cowl and turn it counterclockwise so the flanges lock together, making the tab and flanges are fully engaged. Turn the vacuum Brake Booster clockwise on the Power Brake Booster Holder (J 22805-B) using a ratchet, but don't use any flat-bladed tools. When the installation is done, take off the power Brake Booster holder, fit the vacuum hose and check valve assembly, and put the master cylinder onto the booster, tighten the retaining nuts to 25 (18 ft. Lbs.). Connect the brake fluid level sensor electrical connector, move the engine back to its original position, and fit the left and right engine mount struts. Put the heater inlet pipe in place, reattach the coolant outlet and inlet bypass hoses, and attach the evap canister purge valve pipe, fuel feed pipe, and return pipe. After that, install the air cleaner inlet duct, cross vehicle brace, fill your cooling system, connect the Brake Booster pushrod to the Brake Pedal by using the retaining clip, reconnect the stoplamp switch, and put the left instrument panel insulator back in place.
