Yes, Ckrikos, I have a quarter-inch or better of brake pads left.
Here's a pic of today's damage. It looks worse than it is in this pic. I can peel-off the protector without a problem I think. That foam tape is going to be a pain to remove, though. I have Goo-Gone, which works painfully slowly. The only REAL damage to the surface of the wheel can be seen under the curve of the wrecked protector.
Darn!
