My H3 would make a loud groan (not really a grinding sound) just before coming to a complete stop when braking hard. Mine sounded like the anti-lock brake unit was paulsing the brakes just before coming to a complete stop thereby creating the noise. I don't know if this is what you are hearing or not. I had it at the dealer twice for this problem. The service manager assured me that the noise I was hearing was normal for the anti-lock brake system used on these vehicles. The noise is gone now
I traded the H3 for a new H2 SUT
