I've installed defective/poorly turned brake rotors before. A brake rotors is cut by a lathe. Much like a vinyl record. It is then sanded flat. If the sanding process isn't done correctly, the brake pads will follow the spiral trac and ‘click’.
No, Chapin, it was just the calipers which, as I just checked, one was on the RF where the problem is. Called shop and it’s still covered so I take it in on the 22nd to find out.
