im stumped brakes
replaced everything(brake booster, mc, ss lines,s vacuum line, pads rotors, etc) no air in lines and yet very little pedal pressure, brakes dont start to grab til pedal is at floor. Can build some pressure if i pump brakes but doesnt hold.

brand new brakes all around and the pedal is really soft.. sometimes it goes all the way to the floor no problem.
how do u adjust break pedal pushrod.. and im guessing its behind the pedal?

Sounds like air or the wrong master cylinder or ????? Got me. Air is the first thing that comes to mind. Or one or more of the pads is installed incorrectly or ????? part of one of the brake assy is rust frozen in place? Just wild *** guesses.

if the Pedal is Hard,HARD,and the Brake just don't wanna Grab,but to you they feel OK when you step on the pedal.then the Vacuum hose between the Booster and the Steel line is REVERSED(if you took it off) that little "S" shaped rubber line contains a Check Valve in it that will only Give vacuum to the Booster..not a two way valve..so If the hose is on Backwards,it hits a BRICK WALL,and since the Booster gets NO vacuum assist,it is like Very Bad Manual Brakes.

the only parts that aren't new are the calipers, im gonna tackle this again tomorrow. Hailers, thanks for the link gave me a few ideas. Misterstyx69, kinda hard to screw that one up as the rubber line has a arrow pointing to the engine side. Dustin the check valve is fine.

Did you properly bench bleed the master cylinder? If you didnt do it by the book, you could have ruined a new master cylinder. Calipers even when in need of a rebuild dont generally cause a soft pedal.
Its either the master cylinder wasnt bled properly, or you have air in the system. I worked at a muffler and brake hellhole for long enough to know what I am talking about.
