Abstract

A hydraulic disc braking system is disclosed. The system has a manually operated control device for a cyclist to issue a braking command. The system has a master cylinder assembly having a membrane dividing the hydraulic fluid tank into a variable volume filled chamber and a complementarily variable volume empty chamber. A membrane detector senses the presence of the membrane relative to a predetermined position in the tank and/or a meter measures the distance of the membrane from the ceiling of tank.
