Last month I developed a break squeal in the left wheel during a 500 mi. rally. Very pronounced especially after a left hand turn. It went away, now its back. Put her in the air and the breaks seem to have a lot of drag on that side. Either the caliper piston is not retracting, or it is a warped rotor are my guesses. Since it is under warranty I'll take it in. Going to Maine next week so I hope it gets fixed. More annoying than anything else.
