Brakes locking up
The past couple days when I've left for school in the morning, I have found that the rear brakes lock up under normal braking conditions. Simple things like stopping from 10-0 on a slight hill at the end of my driveway, the passenger rear tire locks and goes into a skid. 2 or 3 stops later after I get out of my neighborhood, things start going as normal.
I'm wondering if maybe the cool morning temperatures are affecting something in the brakes, because as soon as they warm up the issue goes away. My biggest thing is I don't know what could be causing it.
Any help is appreciated

Rust in the drums will do it. Have you gotten into a lot of water recently?
A leaking wheel cylinder will do it also. If your rear brakes are dry, look around the edges of the drum for brake fluid.
You will usually have to replace the shoes after you fix the leaker.

No water other than rain.
Granted, the truck sat for 10 years before I got it, and I didn't tear into either front or rear brakes..
I figured I'd replace the shoes if I have to tear into the drums anyway

X2, a leaking wheel cylinder would be my first suspect.

Well you guys were spot on. I checked the outside of the drums before leaving school, and sure enough there was brake fluid leaking out. Leaking so bad on the drivers side that the wheel is all covered in brake fluid.
I picked up new pads, cylinders, spring kit, seals, locknuts, locknut socket, new axle flange gaskets, and copious amounts of brakleen. I'll probably start tearing into it tomorrow.
