i just had my front brakes replaced this past july. They worked fine for a while, until it started to get cold outside. Now when I back up out of my parking space for the first time after sitting for a while they squeal really bad. Then it is totally fine for the rest of the time, until it sits over night again and then I go out the next day. I am thinking it is probably just from sitting over night in the cold. Though I can't remember any of my other past cars doing the same thing. Not sure what brake pads they used when they replaced the front, could also be the problem. What are your opinions?
