Hey all am fairly new here, have been checking out the site for awhile to help with any issues I have run into and has been great. Now to the problem. I have been fighting with the brakes on this thing for awhile now and nothing seems to work. Had gone through 2 re manufactured master cylinders that were both bad, and then went with a brand new one. Spendy but it seems to be working fine. Replaced everything save for the adjusters in the rear, and even the NLSV. Have bled it oh about 20 times or more and nothing seems to be working. Pedal goes down to the floor when running and will stop the truck slowly, or if you pump a few times but never any real pressure. Thought possibly was the booster and tried plugging the vacuum lines for it and yes pressure, but no brakes. Have adjusted every brake to where they should be, at least according to the book. Till I cant free spin by hand then 2-3 clicks back. Any help would be most appreciated as kinda need the lil bugger to haul stuff and such :P
