Why?? It's always best to update old threads, keeps all the info together.

Did you use cheap pads? They can make grinding noises even if they are new. If your caliper was sticking then it should have been difficult to press back in when replacing the pads. Did you use the correct grease?

Remove the caliper from that side and inspect it again.

The brake dust shield might be hitting the rotor, its easy to bend them.

Did you replace the calipers? they can seize. It's easy to check for, pull the wheel off and if the pad is touching the rotor without the brakes engaged then the caliper is frozen.
