We have a 2006 Buick Lacrosse. We just installed new front brakes. 2yr rotors and lifetime performance ceramic pads. We have used these pads in the past on the car and never experience this issue.
We first noticed an issue when making left turns. When turning there was a constant squeal that seemed to be coming from the front driver side wheel. Noise faded away when driving straight or turning left.
Noise does not seem to be directly correlated to braking and occurs when no braking is being performed.
After further investigation I noticed something that further confused me. When driving up and down the driveway I noticed that the front driver wheel made the noise when backing up, and the front passenger when driving forward.
I can best describe the noise as something like nails on a chalkboard. A constant high pitched squeal. Perhaps metal on metal.
Anybody have any ideas?
