Kind of an interesting problem (just one more I get to solve lol) that I noticed with my new-to-me 14SF that I installed. Already replaced the gov-lock carrier (thanks Rene!) as the old one had busted teeth in the mechanism. Now I'm thinking perhaps I know why... Brakes seem to be good, (pads ok, nothing broken) replaced the wheel cylinders and brake lines, and took the thing out for a spin. Decided to do a u-turn where the rear was off the pavement. Heard a dragging sound, looked out my window, the drivers rear wheel was locked up. It just unlocked by itself after a second, (maybe because I straightened up or increased input to the rear end) and I spent some time trying to replicate the conditions. It started doing it on the pavement as well, but not consistently. If I apply the brakes fairly hard, the rear wheel(s? can't see both) lock up for a split second, hear/feel a clunk, then act normal. Truck doesn't really pull too much, but does more than it ever has. I'm in a neighborhood, so I'm only going 25-ish though. Certainly feels like the rear is what is doing the pulling to one side, but just a hair, probably due to the slow speeds. I popped the wheel/drum off on both sides, and neither show any real damage or obvious problems. Well, the PO DID install the star adjuster backwards, so it hit the spring that runs there, so he decided to cut the teeth off of most of the star wheel. It's more like a rectangle adjuster now. Ok, so maybe it's KIND of broken, but just slightly lol. Since the "leg" that hits the adjuster wheel is not making contact, I adjusted to decrease pad contact with the drum, just to test. Didn't seem to make any difference. When I pulled the drum the first time, it was no tighter than normal, so it doesn't appear the adjuster is just spinning open to increase pad contact. I definitely need to replace that adjuster, but even with it replaced, I can't see why that would be the cause of the binding. I compared both sides, both appear to be set up correctly, (now) and the e-brake works fine. It only drags when I'm turning left, if it were the gov-lock, I'd be inclined to think it would happen either direction. Anyone ever experienced something like this before? Any input on the adjuster being culprit or not? If I can find a truck not buried up to the axle at the wrecking yard, I plan to replace that adjuster Friday, but won't be able to drive/test it for awhile.
