Brake locking spacer thingy?
 

What are these serrated locking brake spacer things called? And where can I buy a dozen or so for current and future project bikes?

Im talking about the bottom ones in the picture. They are used to keep the brake caliper aligned. Most bikes have them, some don’t. I have a very small stock of spares, and I guard those jealously.

i have a bag of substitute locking washers (middle of pic) that work reasonably well in a pinch but are not quite right. I use these ones sparingly. I bought a bag from a general purpose hardware store about a decade or so ago for about $0.80/dozen.

My financial situation has improved to the point that I think I can spring for the real ones, maybe even a bag of legit Campagnolo ones.

I am surrounded by big box bike shops who are often of no help. Anyone know where I can order some, while I also stock up on cable ferrules and cable ends.

the center two appear to be common star washers, both internal and external.

This type of need is why those who fix up bike a bunch (neighbors, family, friends or flipping) should have a good relationship with a LBS. Not only can they give the usual advise but have much more experience and access to parts suppliers that don't cater directly to the retail public. Tektro makes such a serrated anti spin washer. QBP has over 100 on hand distributed between 3 of their 4 warehouses. If your LBS has an account with them (and if they don't they are fairly uncommon in the bike shop world) ask them to search for part # BR7205. Andy

These are readily available
