dc.description.abstractA disc brake is one of important auto parts for automotive industry which effected directly to life safety. The wear of brake rotor war affected to the brake efficiency. Lf the wear of rotor was discovered while operating, the risk of accident shall be reduced. Therefore, a study of disc wear affected to brake distance was the one of alternative for the brake efficiency testing. From this reason, the aim of project is to test brake efficiency from the wear of brake rotor with the experiment conditions from JASO C 406 [1]. By the test conditions are focused on 3 cases of the wear: rotor, little roughness rotor and abundant roughness rotor. The conditions of experiment consist of 100, 200 และ 3000C on the rotor surface, operating pressure 2, 4 and 6 MPa, initial speed before brake applied 50 and 80 km/hr. Based on the result of experiment was revealed that the braking distance, deceleration and the brake ability with deceleration per unit of area. The result of experiment shown that the ordinary rotor at 6 MPa , 300 0C and 50 km/hr. is given to the shortest of braking distance 69.7 m. Although the average of deceleration and the brake ability is take up on little roughness rotor. In case of the longest braking distance was occurred on the abundant roughness rotor. However, from this study is discovered to the high temperature and the high pressure is significant to the braking distance shortened.en_US
