call predator they have replacement parts for you.
That's a good example of why I don't like Predator products..I called them just now, and the guy was very helpful, the official measurement is .080" thick for the BK2 carbon fiber pad. Also, it comes attached to the tip, and the pad being changed by anyone other than them voids the warrantee.
The pad on this one was down to .035" after only 4 tip changes( by another repair guy), which is getting too close to the critical point of .020" minimum mentioned on their site.
Thanks,
Dave
