I was adjusting rear brakes last night and this little thing snapped in half (see image [right]). The linear indent holds my brake cable in place and a 5mm bolt holds this in place. I guess I need to find a replacement but I have no idea where to start. Does anyone know what this might be called? Can I stillfind something like this?
Bike: Old Dawes Horizon (1990's maybe?) Braking system: Centre pull cantilever.
