A hydraulic disc brake device comprises: a base assembly mounted on a vehicle, a sliding assembly slideably mounted on the base assembly, a return spring disposed between the base assembly and the sliding assembly, a brake lining assembly, a control valve assembly disposed on the oil pressure system. An inertial force acted on the brake lining assembly in the case of a brake action will cause the sliding assembly to move along the predetermined arc with respect to the base assembly, the relative movement between the sliding assembly and the base assembly causes compression of the return spring and makes the control valve assembly stop increasing the oil pressure, then the control valve assembly produces a press relief oil space in the base assembly, after the brake lining assembly releases the brake disc, the return spring will close the pressure relief oil space, thus increasing the oil pressure again, allowing the brake lining assembly to clamp and release the brake disc repeatedly. |
