Swapped to disc and now horrible scraping Help

Yes, that is what Scarebird now says to do. Use a belt sander to remove the metal plate on the pad where it is rubbing. we will see how it goes. Still concerned about the groove in the Rotor hat, but I guess no big deal.

That rotor will never know that groove is there. Ride on brother. Keep this in mind, too. Not all brake pads are made the same. They can be the same part number for the same application and be made differently. I can almost guarantee you that you can find some pads that will not require modification. Might take a little leg work to the local parts stores, but it's worth a try.

That said, there's not a thing wrong with removing some material from the pad base. This is hot rodding, after all.
