A friend has recently complained that her brakes are making a noise that scares her.
Her front disc brakes, when cold, make a damn nasty screech. Like if she brakes within a minute of first getting on the road. I heard it last night and it freaked me out too

. 3 minutes later the noise clears up and the brakes will not even screech during an emergency stop. Happens almost every time she starts the car up after it cools down for at least an hour.
There's no noticable scoring on her disc, but her pads are looking a little low. Could they be getting a little glazed or something?
Thanks
