Oldsmobile 18060146 Power Brake Booster Assembly

When you press the brake pedal in these two Cadillac models, a dual vacuum brake booster works with vacuum pulling in on both sides of its diaphragms. Braking pressure partly comes from one half of each diaphragm receiving air from the environment, while the other half evacuates vacuum when you release the brakes, directed through a special air valve. You can't fix or replace any of the parts inside. Before removing the booster, turn off the vehicle's power with a negative cable and disconnect the booster suction tube. Keep brake line integrity by taking off the master cylinder holding nuts and moving the master cylinder without detaching the lines, while being gentle to prevent bends. First, take off the booster mountings and pull out the pushrod from the brake pedal, steady the booster to keep it from bending side-ways. Take out the booster andreasdolase if they need to be taken out. To install, first get the necessary gasket, place the booster in its location, join the pushrod to the brake pedal, and screw the mounting nuts in a firm 20 foot pound force (27 newton meter). When you have the barrier (if used), attach the master cylinder, bolt down its nuts tightly (20 ft. lbs. torque), attach the brake booster vacuum hose, and end the job by reinstalling the battery negative terminal.
