Although this caliper device can already achieve the intended use purpose, for vehicles with frequent braking, when braking, the first and second pad units are relative to the brake disc. High temperature is generated by frictional heat generation, and it is easy to cause the first to cause the disc unit and the second to cause the disc unit to adhere to the brake disc, or easily cause thermal deformation of the component members of the caliper device.

Generally speaking, a moving vehicle can take away a small amount of heat by blowing the air. However, the second unit near the rim disc surface makes the air flow blocked by the brake disc and the rim disc surface. However, it is unable to effectively blow the corresponding junction between the film unit and the brake disc to cool down, which is more prone to the above-mentioned adhesion or thermal deformation. Therefore, the heat dissipation problem of the caliper device needs to be solved urgently.
