• Q: How to replace the vacuum brake booster on 2000 Buick Century?

  A: A vital process for replacing a vacuum Brake Booster begins with checking that the cruise control cable remains free of pinching between the booster and cowl because any damage could occur. First disconnect the negative terminal of the battery. Better access to the installation arises from rotating the engine forward although brake lines extending from master cylinder to brake modulator do not need removal. Begin by removing the master cylinder mounting nuts followed by unbolted brake modulator attachment from shock tower and electrical connection detaching. The Brake Booster should have its vacuum hose disconnected next. Prior to disconnecting the Pushrod from the Brake Pedal keep pressure on the Brake Pedal to protect the brake switch. Screw the power Brake Booster holder (J22805-01) to the booster and tighten the nuts to a torque of 27 nm (20 ft. Lbs.). The dash-mounted booster unlocks through the front while a flat-bladed tool pulls the locking tab out of its mounting flange notch. Simultaneously use a wrench on the power Brake Booster holder (J22805-01) to turn the booster counterclockwise. Remove the Pushrod from the eyehole while taking care to protect the insulator boot before removing the booster. To mount the new booster insert the power Brake Booster holder (J22805-01) and fasten all nuts tightly at 27 nm (20 ft. Lbs.). Put the booster at the cowl counterclockwise to align its locking flanges before tightening the power Brake Booster holder (J22805-01) with a wrench for the locking tab to snap in place. Connect the Brake Booster Pushrod to the Brake Pedal and attach both a vacuum hose and master cylinder. The brake modulator must be reinstalled after reconnecting the vehicle electrical connection. Follow by rotating the engine to its original position then adjust the stoplamp switch and lastly restore the negative Battery Cable.
