The invention discloses a formula student China segmented stepless adjustable braking system. A braking assembly comprises a sliding mechanism which is used for being installed on a racing bicycle, apedal mechanism used for the left foot and right foot of a racing driver to apply force, a control mechanism used for converting stress into control signals and a braking mechanism used for braking the racing bicycle, and the pedal mechanism is installed on the sliding mechanism at the front of the racing bicycle; the pedal mechanism, the control mechanism and the braking mechanism are installed on the racing bicycle through the sliding mechanism. The using method comprises the steps that the position of the control mechanism and the braking mechanism is adjusted according to the height conditions of the racing driver; the racing driver uses the right foot to pedal an accelerator pedal to control racing bicycle power output; the racing driver uses the left foot to pedal a braking pedal totransmit braking force to the braking system; if the braking system breaks down, an overtravel switch is triggered, and at this moment, the racing bicycle power output is cut off. The formula studentChina segmented stepless adjustable braking system has the advantages that on the premise that the braking reliability is guaranteed, the operability of the braking system is improved, the structure is optimized, the weight is reduced, and the production cost is lowered.
