The spring that keeps the two brake pads evenly spaced was bent severly while I was riding recently. A twig must have snagged that tiny hole somehow. When I got it back, i took the pads out and one whole side of the spring was broken off.

I have looked everywhere for specifics on whether this part is available by itself or if I am going to have to buy a whole new disk brake!

The brakes are Avid mechanicals that came with my 05 rockhopper.
