That one goes to the drivers side, and it will drag and not release all the way causing the drivers side to wear faster than the P/S. I disconnected my D/S inside the drum because it would constantly cause that issue your truck has. My truck is single rear wheel with the sterling 10.25 it has floating drums. Sometimes a blown wheel cylinder causes what your describing, look to see if you have any fluid coming out of the drum maybe take off the adjuster plug on the backing plate you might be able to see in with a flashlight.
