Make sure you lube the back-side of the stainless steel guides on the top & bottom of the pads. If the pads won't slide easily, you may have to take a file or grinder to the caliper surfaces to remove the rust.
I bought some of the Permatex stuff recently - it seems to be pretty decent, although for as much as you use on a typical brake job I have enough to last me about 1000 years. It would be nice if they made a smaller size packaging option.
Anyway, my '02 VW Jetta TDI wagon had a similar problem. I noticed that the right rear wheel was building up brake dust faster than any other wheel. It wasn't getting hot enough to smell, but obviously it was dragging somewhat. I pulled apart the rear brakes and found the pads binding pretty bad on the calipers. I pulled off the little stainless steel clips and cleaned up the rust from beneath them and off the pad backing plates so that they fit freely again. The car was probably 4 years old by then, and I've made it a semi-annual task since then. Usually by the second time (4 years) the rear pads are worn enough to replace while I'm in there.
Kind of a dumb design, IMHO. At least VW uses the caliper for the parking brake function rather than the idiot "drum in hat" design (or as I call it "a$$ hat award" design that rusts up, binds up, and burns up. I spent $60 rebuilding the parking brakes on the Liberty CRD after they rusted up and finally one of the linings fell off the shoe and would intermittently cause horrendous clanks and jerks as it floated around in the drum binding up the works when felt like it. To top it off, it wasn't like the parking brake never got used, either. It was used every time the Jeep was parked.
