Default That's a new smell! Right rear tire area

So I got out of my truck today, and instantly noticed a burning smell coming from the right rear tire area.

I figure either the bearing is shot, or the brake is dragging on the rotor. I'm hoping someone more knowledgeable than me can advise me on what to look for.

Assuming rear disk brakes... Most likely a froze caliper either from the slider pins locking up, the flexible brake hose degrading internally, or from the caliper piston itself not retracting properly.

If it's the brakes, you probably won't be able to turn the wheel very easily with the back end jacked up. If you have a limited slip rear end (RPO code G80), then it will be difficult to turn the rear tire unless the transmission is in neutral. Please be careful and use jack stands and wheel chocks to keep the truck from falling/rolling when in neutral.

It would help to know what year and options your vehicle is/has. Please add this information to your signature (in 'My Profile') and attached it to your posts.

The bottom slider on the caliper seems to be locked up, the top one seems fine.

That's enough to do it. If you can't get it loose quickly, a new caliper bracket is less than $20, then you'd need new pins & boots, but it's still cheaper (to me) to buy a new bracket and everything than it is to spend even an hour cleaning up the old one. I just had to go through the brakes on the back of my Bravada.

Thanks swartlkk, that was it. I managed to get the pin out, cleaned up, and then cleaned up the recess in the caliper also, relubed everything, works dandy now.
