Does Anybody's Back Drums Grab So Bad The Seatbelt Chocks You

My 98 4x4 with rear drums does it on rare occasion.
Open up your brakes and use "brake-kleen" or similar and get rid of all the caked on brake dust. Pull off your shoes and lubricate the friction points to the backplate. Adjust everything up.
This usually occurs because moisture in the air (nothing you can do about that) turns the brake dust into kind of a brake dust cake batter and it sticks. One application heats them up enough to get rid of the moisture, thats why they work great after you lock your back tires & hit the steering wheel.
Ride your brakes for two seconds lightly before your first stop helps too.
It's basically a design defect of ALL drum brake assemblies. The drums should be cross-drilled to expell dirt & foreign matter.

sounds like something is prohibiting the auto-adjust mechanism in the rear of your truck from loosening fast enough (sounds like it's tightening just fine).
As p_ferlow, clean out your rear drums, pay particular attention to the auto-adjust mechanism.
Does it spin freely both ways? (you'll have to hold the locking tab off of it)
Does it look like it should be functioning properly?
When you leave your driveway, do you back out?
Do you back in the night before? Do you tap the brakes multiple times when going in reverse? Hiting the brakes, in reverse, will tighten up those rear drums a lot.

My 98 2WD does it. Especially after rain. The moisture seems to take forever to get out of the shoe. The only thing that seems to help is the self ajustment, meaning I back up about twenty feet doewn my street and pump the brake.
I find these brakes to be $**** compared to other trucks I have driven (Chev, Superduty, Ranger, Econoline, etc)
