My bike has a coaster brake (pedal brake).
I am not sure how it started, but it has just started to brake itself even if I don't do back pedal.
It works weirdly that, it is kind of latching the brake when I use the back pedal. Sometimes it gets fine especially when I do a strong pedal brake. But, it usually brakes itself and the strength of the brake varies, and time-to-time it gets fine itself for a while. It does not have a consistent state.
Does anyone have an idea what might be wrong with it and if it is something that I can fix it?
