Thats pretty much what i am hearing more and more. So i guess time to stop much harder for time being. Thing squealed with 37 miles on it when i left the dealer but i disregarded thinking dust ect.. Maybe the test driving people had messed them up. Who knows, Just never had this type of sound so quickly into a car.
What can and does happen with new cars on the lot (and used cars, too) is the brakes get wet (from exposure to rain or the frequent washing the cars are subject too) and rust but the car gets driven very little and the last thing on the test driver's mind is this brake rust.
In fact most often the only "use" the car gets is when it moved around the lot so the brakes get used about as lightly as they can.
With your car with 37 miles it obviously has been driven most that just moving the car about the lot every so often.
But the problem is still the rust this rust gloms on to the pads and affects the friction between the pads and rotors.
With every new car purchase I always arrange to do a brake bedding in as soon as I can after I buy the car. If possible I do this on the drive home. Because in most cases it so happens I buy a car some distance from my house -- 10 miles, 45 miles, even 90+ miles -- I have plenty of opportunity to perform a brake bedding in operation.
This brake bedding in will heat up the pads and allow the more volatile compounds to turn into gas and thus leave the pad material. The bedding in can also remove the light coating of rust on the pad surfaces.
The brakes might still squeal lightly due to as I touched upon from dust build up on the piston dust boots or just because some brake squeal can be normal. But you need to bed in the brakes -- provided of course you have not already done this -- and get them started -- albeit belatedly -- on the road to a long and trouble free service life and probably -- based on my experience over the years with factory brakes -- a reasonably and acceptable quiet service life.
