Hi, Im trying to diagnose an intermittent noise coming from the front of my 2013 Max. when I first changed my wheels from summer to winter, the first time I stepped lightly on the brakes I heard a knocking noise coming from the front. whether going forward or backward. when pressing hard on the brakes its not there. I am not able to reproduce this, as I stated it happens intermittently. To me, it sound like the brake caliper hitting the rim but these are the same wheels I used last winter and I had zero issues then. The only time I hear this noise is when stepping on the brakes.

Any thoughts?
