I tore into the brakes on the truck yesterday and found that both return springs on the left-rear were broken. I'm not sure how that's even possible, but apparently that was my problem all along. I bought a kit that had all the springs and other various small parts for both sides of the rear brakes for $12, and today I replaced everything. After putting the truck back together and going for a test drive, the parking brake light and ABS light on the instrument panel finally went off. I'd actually gotten used to the lights being on all the time, but it's nice to have them working normally again.

The brakes really don't feel right though, but I'm hoping the adjusters kick in and tighten up the rears soon. I'm planning a caching trip on Saturday to Ferron and back, and I guess I'll be shit-outta-luck if the brakes don't feel like they're back to normal by then. If that's the case, I'll have to try to get them fixed at a shop before next Thursday, which is the start of our 4-day camping trip at Potter's Ponds.
