If you ride your bike year round in all sorts of weather, parts here and there will get rusty.
The little spring on the back of the Tektro R559 brake is one such item that can corrode over time, especially if you live in a humid environment by the ocean. It doesn't mean it's defective!
Please try to restore and repair your old things, whenever you can, instead of instantly landfilling them when they wear out.
Compatible for both the Tektro R559 and R369.
Sold individually.

Black square cable pinch bolt washer.
This important and weird black square washer goes under the brake cable bolt and it firmly pinches the brake cable.
If you loose it and try to use a normal easy to find round washer instead, your brake cable will slip when you pull your brake lever; that's not good.
