odd washer source needed
 

I cannot locate a washer that would be used on the rear brake mounting bolt, when the brake bridge is round. Looking at it from the side, the middle is thin and the radius will (hopefully) fit the radius of the brake bridge. This washer would prevent crushing the brake bridge by spreading the pressure around the bridge rather than along a thin line.

The bolt is probably an M4.

I cannot find one locally - does anyone have a source?

Or, does anyone have a couple they would be willing to part with?

Thanks in advance.

I think the bolt is closer to M6. try here

I would expect any half-decent bike shop (not Dicks or Wal-Mart) to have a drawer full of those things. BG is right, brake bolts are almost universally M6 and they are called "curved" or "cupped" washers

Thanks for the replies.

BG, that is the exact washer I need. HR, I will stop at the bike shop and see what they have available.

If they don't have any at least I have another source.
