Braking issue on a 99'

I have a "99" super duty 250 quad cab with 340K on it. Recently while driving it around my brakes locked on after lightly using my brakes. They didnt lock up but they were on and the brake pedal was solid when touched. Could barely pull it onto a trailer under it's own power. Forward and reverse was the same. It sat for a day and all brakes released and hasnt locked up again. I took off all the wheels and checked the rotors for discoloring due to heat from a bad caliper but all were looking about the same. Now I'm thinking possibly a bad master cylinder. It has a hydraulic boost off of the power steering pump. Any ideas? Much appreciated.

Check your slider pins, too. They get rusted up and they stick. I don't think it will cause the complete problem you're having. I think you're on the right path, I'd check the master cylinder, fluids, etc.

Found a leaky hydrobooster and replaced it. Thought that cured the problem but once again when I drove continuous for more than about 25-30 miles it locked up on me again, this time without applying the brakes at all. I'm at a loss here. Starting to think maybe faulty calipers? Maybe a soft line collapsing? Read about the ABS control unit and module, could that be the problem. Without a direction to go this could get spendy and time consuming to start replacing parts......
