So on Monday I a shop swapped in my "new" rear carrier and in the process of dissembling the drums they broke the hardware on the driver side as well as found my adjusters were stuck. As needed they replaced the hardware they broke and installed new adjusters, but they did not adjust the rear brakes in the slightest. Also some how it seems air was let in to the system because when I apply the brakes the petal starts to apply lightly then goes halfway down with no resistance and finally begins to apply the brakes more harshly almost reaching the floor to stop. It also feels like they are being applied unevenly. The parking brake does nothing since the pads are not close enough to the drum and because of the air in the system its not possible to lightly brake backwards to adjust them. I only assume air was let in because my master cylinder is less than a year old as are the front calipers. The pads all around are about 2 years old and look to still have about another 2 years of pad left. The tech said that one of my rear brake wheel cylinders was acting up a bit, but I told him not to play with it if it wasn't going to be an issue. I will try to bleed the brakes either today or next week. Currently I'm not actually driving the truck because I'm waiting on my new y-pipe and sensors to come in.
