I live in Wisconsin and it's been really cold here lately. I've found that if I use the parking brake when I shut my car off that when I start it back up and go that it hesitates like the caliper is still engaged. I just had my rear brakes replaced in Dec and they said the calipers were fine and just needed to be lubed. But now I'm having the same problem again. This is the first winter I've had this problem and I've got a 2002 P5. Any ideas what the problem is? Also, am I doing any damage to my clutch by leaving it in gear when I park instead of using the parking brake?
