So one of my rear calipers on a 99 F450 2wd 7.4l froze . I bought a loaded set and replaced both sides . Bled the brakes and everything worked fine . A day later I go to use the truck and now the brakes are holding a super tight grip on the front , both sides . I shut the truck off and turn it back on , let it idle for a minute and the truck is fine I start driving up the driway and I touch the brakes again , bam the fronts are locked solid again . Shut the truck off and this senario happens again over and over . I'm totaly confused , is there some type of reset or did I bleed the brakes the wrong way ? Its got me totaly baffeld .
