The invention relates to a bicycle disc hydraulic brake system and related components and methods. A manual control device (2) for a bicycle disc hydraulic brake system (1) comprises:-a manual actuation member (6) configured to issue a brake command, and-a master cylinder assembly (7) comprising a cylinder (8), a piston (9) movable by reciprocating within the cylinder (8) against the action of a return spring (10), and a hydraulic tank (20), the hydraulic tank comprises a bottom (23), a top plate (22) and a membrane (25) dividing the hydraulic tank (20) into a variable volume filled chamber (26) and a complementary variable volume empty chamber (27), said tank (20) being in fluid connection with a cylinder (8) in which a piston (9) is displaced within the cylinder (8) in response to actuation of a manual actuation member (6). The control device (2) comprises a film detector device (40) comprising at least one sensor of the presence of the film (25) in a predetermined position in the tank (20) and/or a meter of the distance of the film (25) from the top plate (22) of the tank (20).
