Hey guys my girlfriend just purchased a really nice 1998 lexus 400 and it runs and drives great, but has what hopefully is a small problem. The brakes make no noise in forward motion whatsoever, but in reverse when you have some speed built up and press the brake firmly it sounds like a bad grind very similar as to when your pads go bad. The guy who had it before us said the car had been sitting through the winter and he just put a new battery, new tires, and new pads with re-surfaced rotors on less than a week ago. The confusing thing to me is that if it were just the grind it would seem like an easy diagnosis, but here is the strange part. When you get the grinding noise and keep your foot firmly on the brake I hear a humming or low drone coming from what sounds like under the center console or under the vehicle towards the middle even when the vehicle is completely stopped. You can hear it from the inside really well but the outside I can not hear it. Please guys any help would be greatly appreciated just want to get this really nice car running error free!

Wheel bearing maybe?

see the weird thing is that the noise will persist even when the car is not moving like some type of actuator or motor is sticking on possibly something with the abs? not sure though. any addidtional info you guys might need to help diagnose the problem please let me know.
