Well, the mechanic hasn't been able to recreate the issue, and they say that the brake system checks out. One suggestion they have is that a rock or other obstruction caused the issue and the obstruction is now clear.
It seems to me that an obstruction would continue to cause the problem on the uphill and flat part of the road as well, not just the downhill part. I can't figure out why the one downhill part consistently caused the grabbing and grinding sound.
