TL;DR - Brakes are "locking" when slowing to a stop, help me.
As this is my first post, I'd like to apologize for coming straight here to ask a few simple questions; I admit I registered to finally get a straight answer on this, as this forum seems to be the best source for knowledge and help.
We'll start off about one month ago on a trip to pick up a dresser in my wife's 99 Ford Ranger, regular cab short bed, 4x4. I parked it on an inclined driveway and engaged the parking brake. After loading up, disengaging the brake and driving off we got about 100 feet before it stopped moving (this was a slowly advancing stop, not abrupt). Reverse worked fine, but it wouldn't go forward. We took it to a garage not far from the house and they pulled the drums, cleaned and adjusted the brakes and springs, put it all back together and said we'd need new e-brake cables. Now, when slowing to a stop, the brakes jerk and try to lock up. This doesn't happen all the time (especially after taking the drums off and cleaning them).
Here is what I think I know, based on the research I've done:
The front rotors are warped, as there is catching when slowly coming to a stop, that familiar back and forth.
The drums in the rear are no longer circular, and this is causing the jerking/locking.
The hoses coming to each caliper/drum are a little clogged.
The pistons in the front calipers aren't returning to open position, because it feels like I have 500lbs of crap in the bed when I don't.
My question is, in what order do I investigate the problem? I don't want to replace lines if the proportioning valve is toast, and I don't want to resurface the drums if I need new calipers. Has anyone else had the locking issue?
