GRINDING NOISE

Pontiac Bonneville

Hi, ok so I havent been on here in 6 months, iv ben sick, and I used to be a moderater anyways I dont know what happend, ok so im ase certifed and im struggling with this car, maybe u guys can help

its a 2000 bonneville pontiac 65, k, I just replaced the wheel bearing on the front driver's side. About 4 months ago, we noticed slight rotar warping starting to occur, not much, about 6 months prior to the bearing, we replaced all 4 pads and rotors, now we have the car again and when braking, there is a small grinding noise almost like a screching or scraping noise along with a gridning, it used to only happen after driving for long periods of time, now its happing almost instantly, u only feel and hear when brakes are more or less fully applyed, we cant figure out if its in need of new rotors in the front, or just to resurface them, and if we replace the front rotors, should we do the front brakes as well? The brakes are less then a year old, but the bad wheeling bearing caused the rotor to warp, so. Any suggestions would be appericated, were stuck here at the shop.

thanks!

If the rotor is warped even a little, I think you should change it even if you can resurface the thing. It all depends on what whoever is paying for it thinks, And since the rotor warped, you should probably go ahead and replace the pads too. Just so that everything is new. I had the same problem on my wifes 2001 Saturn SC2 and she did not sound right until we changed ev erything.
