Re: changing a power brake booster off a 84 ford f350...
Pretty simple repair.I even did this alone. DO NOT disconnect the brake lines unless you are changing the master cylinder out with it. Unbolt the master cylinder and move it forward slightly. From inside the truck,unbolt the brake pedal from the rod, leave the pedal hanging. Remove the 4 bolts at the firewall that retain the booster.From outside the truck reach in and draw the old booster out.You may have to move the master cylinder up or down to clear the booster. The rod to the brake pedal will come out with the booster,make sure you put it back on the new one.

check your brake booster and also make sure the rear shoes are adjusted up where they belong. If they are not adjusted up the brake pedal will go farther and farther toward the floor and get spongier as they go farther out of adjustment. If you adjust them up and they back down again change your self-adjusters and springs. They are readily available at your local parts store.
