Power brake issue

[B5fourspeed]

Finally fixed my brake issue.The calipers were on wrong.I had the calipers rear mounted.The right caliper on the right side and the left one on the left side.The bleeder screw was at 10 o'clock on the right one and at 2 o'clock on the left.I if moved the caliper to the front side of the rotor the bleeder was at about the 1230 position.Once I changed the calipers to the front side I just bled the front brakes and then my brake pedal was perfect.I used the same slider calipers conversion kit on my last Cuda in 2008.I rear mounts them on the rotors and had great pedal feel and brakes.This time I also changed my bleeeder screws to speed bleeders.Super easy to bleed the brakes by yourself using them.They work great

B @B5fourspeed -
I have the EXACT issue and symptoms you described.  Bench bled master - Bled system with 2nd person pumping brake, etc.  No bubbles.  Rock hard pedal without booster (engine off) - Low pedal with booster (engine on). 

I don't understand your resolution.  My calipers ARE front mounted, and I would say the bleeders are at the 10:00 and 2:00 positions you mentioned.  I don't understand how the bleeders could get to the "12:30" position you described.  Do you have any pictures of your final resolution?
I have attached a picture of my front right caliper. Hopefully, you or someone else can help me understand what is incorrect and how to resolve.
Rears work fine. Fronts work, but pedal is soft and way down to floor.  Using DOT5
More bleeding?  Thoughts?
Thanks.

Your calipers are way different from mine.It looks like your bleeder screw is at the top.I went thru my issue for 2 years.I called Dr Diff and he saw my issue.I would give him a call.If you spin one front tire and step on your brake pedal and nothing happens with the car not running your issue is the front brake setup.Can that setup be rear mounted on the rotors?
