I was wondering my anti-lock brake light has been on for some time. I was wondering if that was the trucks way of saying there is air in the rear brake lines? I know its not the front I replaced the rotors and the pads on both sides and blead the lines. but when I have to get on the brake a bit more than normal the tires will squeel.

Check the Abs sensor mounted on the top of the rear diff . The sensor will collect metal filings just thru normal wear & tear . Clean any metal filings on the sensor & retest / drive your truck to see if the problem is rectified .
