I need to know whether or not I can use the power brake calipers and lines and/or master cylinder and Booster off of a 77 LTD to convert my 78 F100 Custom to power brakes....any help will be greatly appreciated!!!

 

if you allready have disc brakes all you have to do is apply a power booster and master cylinder from a same year truck or one that uses the same system it ain that tuff just check out a truck the same as yours at the bone yard. remember you need to grab the vacum hose and clamp and the fitting on the intake manifold

 

Read the "Brake Upgrade" article inthe tech articles, it will answer some of your questions even though the article is for 78-79 Broncos (basically the same truck as yours).
