A barrel by any other name...
Looking for the nomenclature of a part. Rebuilding an early 70s Gitane Inter Club. When I removed the Weinmann Symetric side pull front brake caliper from the frame it only had one of the "contoured barrels" that rest against the frame. I am looking for the actual name of it, so I can order one. It is part number 58 on subdrawing 4200-5 in the picture below. If the local bike shops were open, I'd just run down there, get some advice, and give them a little business...
Thanks!
Thanks!

Also known as a Concave Washer. Front Brake should only have one, #56 . You're asking about the rear bolt part #'s. Check for bolt hole diameter. https://www.ebay.com/p/2255012477

Only the caliper needs to be kept snug up against the frame and the caliper is only on one side of the frame, thus only one curved (not concave) spacer/washer. However if the center bolt is long enough or if one is running fenders I really like a second curved spacer. Andy

Many bikes have tubular rear brake bridges and the concave side of the washer compensates for the curve of the bridge and the flat side gives the caliper a flat to tighten up against. Some bikes (all of mine) have flat surfaces machined into the brake bridge so the caliper can tighten directly up against the bridge or use a spacer that's flat on both faces.
