That's what I hear driving along! Front brakes on my 275 squeak when rolling at low speed. The brakes aren't even applied. Seems to happen most often when I have steering lock on, and is worse with a bit of heat in the brakes. Brakes don't feel like they are binding but I haven't bothered jacking the car up. This isn't normal brake squeal which happens when brakes applied sometimes (that doesn't bother me). The car has grooved discs on it which I believe is not standard spec for 275 Cup S. Dunno if that makes any odds? I noticed a tiny bit of squeal when (more like a squeak squeak!) when cornering after driving the car hard for a while when I first got the car. Now it seems to do it just from cruising on motorway for a while. Any ideas? Case of TADTS?
