How do you change a brake booster on a 1963 Mercury Monterey?

To change the brake booster on a 1963 Mercury Monterey, first, disconnect the negative battery cable and remove the master cylinder from the booster. Then, unbolt the brake booster from the firewall, usually requiring the removal of several nuts or bolts. After taking out the old booster, install the new one by reversing the removal process, ensuring all connections are tight and properly aligned. Finally, reattach the master cylinder, bleed the brakes, and reconnect the battery.
