Front brake Locks up on 2003 4x4 chevy 2500 HD

Brakes Lock up on the front of my 2003 2500 Chevy HD duramax diesel 4x4. I have already had to replace the brake lines, calipers, and rotors trying to resolve the problem, but still happening. All I have to do to get the brakes to release is to crack one of the front brake bleeders, and it will work again till lock up.. Anybody have an answer

SOURCE: 78 chevy malibu fron left wheel keeps locking?

sounds likeyou have air in the line. what you can do is bleed your brakes and while you are down there add some moly lube to the pad ends. if it still doesnt work you might have to look at the master cylinder.

SOURCE: 93 tracker front brakes wont release without opening bleeders

Try loosening the line at the master cylinder when they are tight. This is odd, usually the brake hoses would have fixed this problem. I don't see how a combination valve could cause this but let me know if popping the lines loose at the MC releases the brakes. It could have a bad master.

SOURCE: Replaced all brake lines, rear

It sounds as though where the rear brake lines meet up with the master cylinder; there is probably a piece of dirt in the lines that could be blocking any fluid from getting in. To test this, I would remove the brake lines from the master cylinder and then remove the master cylinder. Once done, have the master cylinder cleaned inside out. This will remove the dirt particles that are clogging your lines.

I am told the glow plugs heat up in "firing" order, also the Duramax uses a intake air heater to warm the air on cold starts.

2500 hd duramax crew cab 4 WD pulls right. Both

First try rotating the tires to the rear. Does it go away? If you apply the brakes does it pull to the left? Could be a draging caliper or the slides may be hanging up.
