It's a bad thing when smoke is pouring off your right front brake caliper, right? Especially when you're 400 miles from home?
I'll be taking it by the dealership in the AM. Gillespie Motors, where I used to have it serviced, is nearby, but I figure the Bimmer shop is more likely to have parts in stock so I don't have to spend an extra night in Tennessee. Hopefully it's just a warped rotor and all I'll need is a set of pads and a replacement disc.
Since I'm broke, watch for the Big Gun Sale when I get home. :(
