Hey guys

When I brake in the 01 LS Ultra, there appears to be a noise coming from the glovebox (kind of high pitched)... It comes at the end of the braking, lasts 2-3 seconds and then goes. Anyone have any ideas on what it is?

Also, during heavy brakes, when i let go of the brake slightly, there is a vibration like thing... Is that normal?

Thanks
