Question
QUESTION: I just converted my jeep to a power brake system.The pedal feels as it should when not running,however when running the pedal goes to the floor with very little stopping power.I have no leaks and have also replaced everything on the rear. All wheels are bled well, so I'm now scratching my head.

ANSWER: What exactly did you do when you converted to power brakes?
Just install a booster? did you change the push rod? If so, is it adjusted properly? Where did the booster come from?

---------- FOLLOW-UP ----------

QUESTION: the booster came from an 87 wrangler. as far as adjusting,where would I begin? there didnt seem to be room for adjusment.

Answer
While running, pull the vaccuum hose from the booster and plug the hose. The brakes should work, but the pedal should be hard. If it's soft, you have a bad booster.
If it's hard, keep you foot on the pedal as someone plugs the hose back in. The pedal should drop a bit, the remain hard. If not, the booster is bad.
