Default Brake Issues after the LSx Upgrade

Ok so I finally decided to move the car today and the brakes are showing issues. I have rebleed the front and gone through a bottle of fluid. Still it does it. With the pedal to the floor on the first push I can turn the front wheels by hand... its hard but I can.

I can only think maybe the rear brakes? There are no leaks... I don't think its air in the rear but I am going to try it... I am not sure what to think...

Also if I pump the brake it gets firm and will not move.... so I am not sure what to think... any idea's? I never heard of anyone saying the MC wasnot big enough but thats my first thought....

I was thinking maybe not enough vacuum, or the brake booster being shot.

Hmm I never started it I guess that could be it.... I will try it tomorrow with it running. I have never had a one need it to be running though...

I was wondering if I would have to bleed the ABS at all?

Well I know on newer vehicles the ABS does the bleeding for you. Hook up a scanner and run a program.

Anyways, that's besides the point, the ABS unit does have bleeder valves on top if you haven't taken a look before. I know my 93's does.
