My brakes squeal, but only while I'm reversing down a hill. The brake pads are new. What else could be the cause of this sound?
This is a 2012 Suzuki SX4.
Since it happens primarily after your car has been sitting idle for a while, I suspect the brake rotors are getting a light coating of rust on them due to exposure to the elements. The first time you apply your brakes the brake pads will remove the rust from the rotors. This is common and nothing to worry about. But not all brakes will squeak. My daughter's Fiat 500 sits in the same garage as my Chevy truck. When she backs out of the garage in the morning her brakes squeak - every time. When I back my truck out of the same garage having sat overnight my brakes don't make any noise.
