Just started to notice that when it gets hot the back brakes seem to stick the pedal returns all the way so it's not the cable . no problem when its cold. ideas ? before i pop off the hub .
If the brake cam "pivot" bore is dirty or corroded, it could bind as the alloy backing plate heats up. Take it apart, clean it out carefully and lube it sparingly with a light grease (I have just the stuff: high end bike hub grease).
