This split type structure requires the manufacture of the front fork and the brake separately, and then assembles the disc brake to the front fork. On the one hand, there is a certain problem in the overall structural strength, and the tab on the front fork for mounting the disc brake or the mounting. Bolts are easily broken and the safety is lacking; on the other hand, tolerances are easily generated during manufacturing and assembly, and accumulation of manufacturing and assembly tolerances may result in poor assembly and also poor safety; The tabs on the forks are fixed, and only the disc brakes of the corresponding specifications can be used, which brings trouble to the bicycle manufacturer or the consumer to select the disc brakes, and also makes the manufacturing and use costs high.
