How can I tell if my brakes are binding, if thats possible? I don't hear or feel anything while driving but there is a burning smell from the back end somewhere

Drive it a good while. Park it. Get out and touch the wheels. If your brakes are dragging, the wheel with the dragging brake will be very hot.

You can also Jack each corner up one by one and try and spin each wheel by hand. It will be evident if there is one that is dragging more than the rest.

BTW I find that a laser thermometer works very well if you want to see which is hottest after a drive. I usually point it at the rotors and one corner will be 2x to 3x as hot as the others.

I have become somewhat of an expert in this as my wife's Toyota had recently gone through about 8 calipers in 5 years. Which is exactly why it is gone now.

I thought of that when it happened, but didn't think it entirely through as I touched the disks of my two rear brakes. one was hot, one , well, I burned my finger. since I've never done that before, i didn't know how hot it should be.

so, why would it be binding ?

Cheep start would be a can of brake cleaner. I assume you've driven through a lot of salt this winter in Virginia
yeah,I missed all that fun. I was in Cabo:drinks:for the week

On a previous truck, I have had a stuck brake caliper and the caused the brake pad to get extremely hot and give off that burnt brake smell. I had to replace the caliper.

so, the caliper is sticking, intermittently . do I replace the caliper or rebuild it? (as if I know how to do either of those) The shop said when it fails, it'll be about $800 for new calipers, pads & rotors for both sides (he said its best to do both sides)

any thoughts or ideas?

Never a BAD idea to keep brakes matching on the axle. Personally, I would replace all the rear pads and get a pair of caliper rebuild kits, but then I'm fairly stingey (not that you'd know since I have a JKU) and wouldn't replace a caliper that isn't actually broken.

Rebuilding calipers is easier than it sounds, but either way you will be removing the caliper from the jeep. Basically, once removed you will remove the piston and replace the sealing ring(s?), replacing the caliper guide boot, regreasing or/and replacing the guide pin, and then reinstalling and doing a brake bleed. It sounds more complicated than it really is.

If you've done any wrenching on your Jeep, it should be pretty quick and easy, and I'm sure there are local Jeepers who would be happy to help. Not sure where you're at, but here in the Northern half of VA, the folks in NovaJeepers are awesome and always willing to help and impart knowledge.

That $800 is very very high for that work. I know the shop has to pay labor and make a profit on the parts, but the work is very easy to do yourself for much less. You can buy new calipers for about $75 each, rotors for $45 each and brake pads for $36 for the set which covers 2 wheels. So, you could do that work yourself for $276 total. But that work is only needed if you let your brakes wear down to nothing. Do you know which caliper is sticking? If you do, I would just replace the caliper and be done with it. If the pads have gotten worn too, then replace those. Brake work is pretty easy. NAPA even has rebuilt brake calipers for $57 each for your 2012 JKU. Replacing the caliper is easy. Once you remove the bolts that hold on the caliper, you just unbolt the brake line from the old caliper and screw it onto the new one. Get it mounted back on the Jeep and bleed all of the air out. Check out Youtube. I'm sure there are tons of videos showing how to replace a caliper.
Here are some links to the parts you would need.
