F-350 brakes dragging/stuck
 

99 F-350 4x4 diesel with 122,000 miles. Replaced pads and rotors at 105,000, All was well until I got sick and truck was not driven for several months. It is so bad now that we had to use 4 wheel drive to move it in 1" of snow. It seems to be getting worse - truck will barely move. Is it possible for master cylinder to fail and keep pressure on the system? Any/all suggestions are welcome!

Never seen brakes do that, even with the hydraulic assist you have in that truck. If you think it may be brake related, try going to one of the brake calipers and opening up the bleeder screw. If you get a good squirt of brake fluid then I suppose in rare/super-odd occasions the booster or master could hold pressure like that. To be honest it sounds more like a driveline problem like transmission or transfer case. Sometimes a bad torque converter will cause that. Lesser engines will usually stall out with a bad torque converter but your diesel will probably blow right through the resistance.
