Ruh Roh.

Some how, the return spring between the pads got twisted up like a little wiener package. The symphonic metal grinding was the rotor as it was eating up this arm of the spring. I don't know how this could have happened but I'm hoping it's just some freak thing and nothing symbolic of what's to come in my life.

This pad took a little beating during the ordeal but I think I can still use it a bit longer before I rebuild the bike.
