Grinding brakes Options

[Mattattack]

So I've been hearing some metal on metal grinding while braking AND while in motion, I figured it was brake pads grinding into the rotors so I put some new rotors and pads on. While the old rotors were warped, even after i put the new ones on the sound is still there if not worse after spinning the wheel while the car was on jacks. could a wheel bearing or caliper be the culprit? Any knowledge would be greatly appreciated.

The problem is on the rear passenger side. Thanks so much for the in-depth explanation, I'm going to test that wheel bearing and dust cover now and see if i can't rule those out before anything else. Would it just be a faint vibration in the coils or something much more noticeable?
I can also take pics if that would help.

So, you have the disc/drum brake configuration on your rear? My 94 just has drums on the rear, so I haven't seen how the rear caliper attaches, but suppose it's much like the front, except the rear wheels are fixed so aren't used to steer.


The vibration due to a bad wheel bearing is readily noticeable by your hand holding onto the coil spring (not faint) when the tire is rotating freely. And, while you are doing that test, you can be listening to where the sound is coming from if not a bearing failure.

BTW: How loud is the noise?
