Today this happened for the 2nd time. I use the park brake every time I
park the truck, and today when I released the brake with the little
left-knee handle, the brakes did not release. Because I have a 4WD, but
in 2WD at the time, I'm assuming the drums are locking up. After I
apply some torque from the engine, there is a frightening "SNAP!" and
then things rotate as they should.
The first time this happened, I was driving through wet, wet slush in
the spring-time. I parked the thing and the weather turned cold. I
assumed that there had been water get somewhere and it froze up on me.
But not this time. I parked the beast Monday night and today it was
"frozen" up on me again.
Is the braking system trying to tell me something? Should I be
dismantling and cleaning something?

It's certainly worth a look. Any "frightening "SNAP!"" is definitely
cause for alarm. I'd have that thing on on jack stands and the wheels
off to see WTF is going on..

I believe there was a TSB about this. The brake shoes swell up with moisture
and lock up or drag under certain conditions. If the shoes are original, I
would change them and check all related hardware.
