Okay, I have searched this until I am blue in the face! I cannot find the answer and I can't be the only person this has ever happened to. I took my calipers completely off of the truck when I replaced the front pads. When I put them back on, I now have no front brakes whatsoever. When jacked up with the brake pedal pushed all the way down, the wheels still spin freely. I bled the rear brakes just fine. The front ones have no fluid coming out of them when I try to bleed them. It has been suggested that I perhaps put them on the wrong sides when I reinstalled them. I don't believe that is the case as the bleeder nipples are on top. Any help would be greatly appreciated.
