Patent number: 10066688Abstract: Disclosed is a caliper brake apparatus. The caliper brake apparatus includes: a housing that includes a piston capable of moving straight; a carrier that is combined with the housing and mounted on a vehicle such that a disc of the vehicle is positioned therein; a pair of pad plates that is brought in close contact with the disc by straight movement of the piston; and a pair of guides that couple the pad plates and the carrier to each other, in which the pad plates each may have a sliding groove at both sides and the guides each have elastic members that can slide along the sliding grooves. Accordingly, it is possible to ensure sufficient gaps between a disc of a vehicle and the pad plates when the pad plates are separated from the disc after being strongly pressed to the disc of a vehicle.Type: GrantFiled: September 1, 2016Date of Patent: September 4, 2018Assignee: HYUNDAI MOBIS CO., LTD.Inventors: Sung A Kim, Se Hoon An, Byeung Su Kim
