$350 later, I finally got the brakes on my truck mostly finished. At least it's safe to drive now. I replaced the rotors, wheel bearings, brake calipers (both sides, now), and pads. Bled the system and now they work fine. The ABS was causing some strange problems on my test drives. Apparently the front wheel ABS sensors are giving bullshit signals to the ABS computer. Hopefully that's the cause because an ABS computer is going to be really spendy. I found the fuse for the ABS and yanked it. Everything is normal now. This tells me that I need to replace the ABS sensors, I hope. That's $100 if I do it myself. I have to thank Auto Zone for one thing; they offer a military discount.
