Hydraulic disc type brake mechanism capable of reducing eccentric wear

The utility model relates to the technical field of brake equipment, in particular to a hydraulic disc type brake mechanism capable of reducing eccentric wear. The structure is reasonable, the splayed eccentric wear problem is effectively solved, the replacement frequency of the brake pad and the brake disc is reduced, the braking effect is improved, and eccentric wear is reduced; comprising a two-way oil cylinder, two levers, two caliper bodies, a supporting rod, two pin shafts and a brake disc, the two ends of the supporting rod are hinged to the middles of the two levers respectively, the output end of the two-way oil cylinder is hinged to the bottoms of the two levers respectively, the two pin shafts are rotationally installed on the two levers respectively, and the two caliper bodies are rotationally installed on the two pin shafts respectively. The pin shaft is sleeved with a damping centralizing sleeve used for increasing the damping amount between the caliper bodies and the pin shaft and the damping a
