I'm assuming you have or will remove the calipers and rotors to check if the wheel bearings are contributing to the problem.
Past this it may get a bit more complicated and without having completed the basic troubleshooting steps above it would be difficult to determine.

There should be no clearance between the pad and rotor. They stay in constant light contact when properly installed / maintained. A stuck piston or corroded slider pins will cause a major bind as described above in the first post.

can you lube pins? what kind of lube?on other cars I have tried neverseize,while I endorse it whole heartedly for other applications in this case it did what it's most famous for... made a big mess,chassis grease,GM brake lube which I later found out it is intended for lube on backing plates of drum brakes.these swelled up rubber parts and made the problem I was trying to cure worse I had a tube of silicone grease a friend got from the factory where he repaired the production machines but thats long used, this stuff worked pretty good. Is there a lube specific for disc brake hardware some have said no lube on disc brake hardware said if pins look cruddey trash 'em as they are plated(cadium?) after they get heat cycled the coating flakes they get corroded and start to hang up

Remove clean with brake cleaner and use Hi temp brake grease
Have done this on GM, Ford, and Mopar. Used to buy the little plastic packs for a $ or so which aren't suffient for a brake job. Advance was out of them about 2 years ago so I bought a "lifetime" supply. A jar containing several ounces with a brush in the lid. Cost was about $5 OR $6. My "lifetime" supply is down to less than half a jar as I have done about 8 brake jobs since then. As I said remove the sliders, clean with brake clean including the recess in the calipers. Let dry thoroughly, grease into the recess in the caliper using a coffee stirer or similar improvised tool, use the slider inserted into the recess to make sure you have enough grease in there and force the air out. Some applications require the slider to be inserted and then snapped into a rubber or neoprane bellows like sleeve.
Don't have to do this every time but pull out the guide pin and if the grease is almost nonexistant it needs to be liubricated.
I would be very hesitant using white lithium grease. Silicon grease might work as it is usually stable under Hi temps.

I've never had an issue with lithium on the pins, keep them in good repair and you wont have trouble. I have had a few frozen though and they never re-froze after I cleaned them and greased them.
