This is something I have a problem with. I've driven all manner of heaps-of-crap cars over the years, many of which have had sticking and binding brakes, and you can tell.
If you can push the car with one hand, then a brake isn't binding. The moment a brake even slightly binds, you can instantly feel the car won't roll easily, and will come to a noticeable stop all on it's own. This is best felt in traffic jams: you pull away up to about 0.25mph, and then dip the clutch. Usually the car will roll on for a surprising distance, but if instead the car then perceptibly stops, the brakes are binding.
But.. if they are binding, and the caliper sliders haven't been lubricated, I'd be back to whoever fitted the pads and discs, having a bit of a rant. It's not rocket science to make sure the caliper is serviceable when pads are fitted, it's just that most garages couldn't care less.
Have you had the brakes apart since the smoke incident?
