nfisher by chance when you removed the caliper did you remount it on the wrong side of the caliper mount? The caliper mounts on the inside of the caliper mount, i.e., the side closest to the brake disc. The Tusk pads should work fine (assuming you were sent the correct ones), as I have them on my bike and they work great. I don't recommend sanding or grinding anything before you double check your work (parts diagrams are a great help if you don't have a service manual). Good Luck :cool:
