79 ford f150 brakes
Just picked up a 79 f-150 with 1 ton axles and 4 wheel dual piston disc brakes. Problem is the brakes work like crap. Pedal goes to the floor. Has stock f150 master cylinder and booster. I replaced MC with one from an f250...no change. Brakes were completely bled and have good fluid flow, but when you try to stop this beast it just wont work. Wondering if that MC and booster is too small to push enough fluid to stop it. What MC and booster should I use? Can I use one off a late model f350?
