Alright well here it goes:

I just replaced everything brake related in the car, just about. Pads, calipers, and rotors. When all 4 tires are off of the ground only the left side spins. The front right doesnt spin at all and the back right spins but seems sorta stuck. The car drives fine at first but then pressure builds up in the brake system and eventually it just locks up. I thought it might have been a sticking caliper, now Im just not sure.

Things that I am thinking are brake master cylinder or perhaps the rear transfer case or something...

The car has a welded center diff if that effects anything.

Please posts any thoughts you have or if you need more information.

Thanks and I guess this is my welcome back to the DSM world.
