Hydraulic braking systems today are a trend, popular, and must-have for advanced cyclists. And the more bicycles are sold on the Hydraulic Bicycle Brake (as cyclists call hydraulic brakes), the more questions arise. Unlike mechanical disc brakes, in a hydraulic system, the force from the brake lever is transmitted through the brake fluid. That is, the effort is no longer mechanical - there is no cable, there is nothing to pull. The brake line contains the brake fluid, which pushes the calipers in the brake machine. A completely different principle of operation, direct transfer of force from the brake lever to the calipers and pads.
