Does the brake handle of the bicycle belong to the control part?

The first is the inspection of the brake handle, because after a certain riding time, the brake handle will inevitably fail. Therefore, every time you ride, check whether your brake handle is abnormal. For example, whether there is abnormal noise and whether the braking stroke has changed.

If the above abnormal situation occurs, it is likely that the braking system has failed. It is possible that there is dust accumulation at the turning point of the handle due to friction, resulting in abnormal sound or change of hand feel.
