Embodiment
As illustrated, a kind of brake gear for being fixed on bicycle contact pin groove described in the embodiment of the present invention, including：As schemed
Shown in 3, the middle part processing interstitial hole 51 of brake disc 5, the left and right sides of brake disc 5 processes left part projection 52 respectively and right part is strengthened
Locating slot 53 is machined with set 54, left part projection 52, the right side of brake disc 5 is also connected with brake circle 55；As shown in figure 5,
Through hole 61 is machined with location-plate 6, the size of through hole 61 is consistent with interstitial hole 51, and one end bending of location-plate 6 forms folded plate 62,
