Urgent help - Front brake problem?

[Baryonyx]

I think I'm suffering a bit of this at the moment. The car's steering feels slightly heavier than usual and when I stop the car, occasionally the front N/S wheel feels hotter than the rest and there is an awful stink coming from it. There is noticeably more brake dust on that wheel that on the front O/S. Brake performance feels normal otherwise, but I know something is not quite right.

There seem to be a few local German car specialists in the area, and a few claiming to be Audi specialists. I doubt fixing a sticky calliper is really all that difficult but my trolley jack broke a few weeks ago, so I suspect taking it to a garage will be quicker and easier. Hopefully they won't have my eyes out for it!
