Drum Brake Hangup
My right rear brake hangs up pretty much every time after it rains, it only does this the first two or three I use it after sitting. Also if I need to stop in a hurry for some reason the right rear will lock up and the ABS will not do anything as far as not locking the wheel.
Does anyone know why my 2000 ranger 4x4 would do that and how to fix it?

I'm not the sharpest tool in this here shed, but here's what I'd check...
Pull the tire and drum. Is there even the slightest hint of gear oil in there? If so, the oil will cause the grabbing, especially when wet. If the axle seal is the problem, you may see a little wetness on the backside of the plate, which you can see just by looking under the truck.
Sticking wheel cylinder? cheap fix.
ABS issues? My only experience is with the older RABS system. No opinion from me here.
Hope this helps...

One may just be all corroded and nasty... Drums tend to do a great job of holding a couple pounds of rust and shoe material until you take them off... If you get the drum off and all looks OK, except for some rust, clean and grease everything that should be cleaned and greased, and try it again... If it's still shot, you may need to do a rear brake job.
The ABS wasn't doing anything because it doesn't look at each rear wheel individually. Even though it may be 4 wheel ABS, you have to lock up BOTH rears for it to do anything, since the sensor for the rear ABS is also your speed sensor, located in the rear diff. That's also the reason why when your speed sensor goes, the ABS light will usually kick on, and will sometimes engage the ABS on gentle rolling stops until you replace the sensor. Since you still had one wheel (and the carrier in the diff) rotating, the ABS doesn't think anything is wrong.

Also, the OEM brake shoes are good at sucking up water and grabbing. Ford's drum brake adjusters easily rust up and stop functioning. My Ranger's passenger side adjuster siezed and the driver side adjuster worked OK causing my rear brakes to act kind of like yours. Check the adjusters - they may be contributing to the problem.

hey
... grease the slider pads and the main pivot at the top for one... as well, as someone said, take your brake adjusters apart (both sides and they are 3 pieces in total)..... mine were so seized i never knew i had rabs until i completely overhauled the back brakes....... and now i hear that faithful clicking noise on many stops...... i guess i'm hard on my brakes.

These trucks are so light in the back that it's pretty easy to lock up the rears and not the fronts, unless the truck is loaded down... Which is probably why they only had RABS for awhile... It was the most effective.

Just to be sure, pull of the drums and do a quick inspection. Make sure the wheel cylinder is not leaking. They can do the same thing.
Nothing to really worry about.

Ditto to what Beast just said. My '99 x cab does that every time it sits in the rain. It's the worst when I don't have my winter weight in the bed. Keeping the brakes adjusted all the way up seems to help a little. It goes away after a couple hard stops anyway.
