Replacing my old V Brakes, got sold some Shimano BR-T4000s.
What I found is they don't sit quite flush on the bosses. There's an internal ring that's a bit larger, that ring is just a bit deeper on the old breaks, and just a bit shorter on the Shimanos. While the pin for the spring fits in the hole, there's just this like 5mm gap between the brake and the base. The boss also doesn't quite make it through to the other side like they did on the old brakes, and the included bolt is a bit shorter.
Is it safe to install these? Or do I just have mismatched parts?
