Ive been having some brake issues with my 94 GT. When i bought the car it had a dual piston swap. The calipers wouldnt release all the way so the 2 fronts were always dragging. So i swapped it back over to the single piston calipers and now i have no pedal. I have to pump it atleast 4 times before i get any sort of pedal. I replaced the master cylinder and bled the crap out of all four corners. But still no pedal. Any ideas??

Needs more bleeding. Sometimes a vacuum pump and/or the 2 person bleed technique just won't cut the fat. Sometimes, you have to bring it to a shop with a brake system flusher, this is a unit that will hookup directly to the master reservoir and force fluid through the lines, forcing a bleed.

I guess all i can do is try it. I had 2 of my mechanic buddies helping me mess with it so i know the 2 man bleeding was done correctly.

Yeah, but replacing the master introduced air into the very beginnings of the lines(unless you were smart and clamped the rubber lines at the wheels, this would create a hydro lock and no air would enter).

To properly bleed that out, you'll need to have bled it enough to use probably over a quart of fluid.

I bled almost a full one of the big bottles you get from autozone.
