摘要:An improvement in automotive industry; high coefficient of friction and wear resistance-non asbestos friction pads can be produced. Various types of test apparatus are constructed for wear, friction and noise level detection. In this study, natural dust reinforced brake pads were tested and characterized by SAEJ- 661 standards. For this purpose computer aided new type of brake pad friction tester produced. This test machine consists of hydraulic control, mechanical design, and automation systems. The main difference of this new type of tester compared to other is that brake pads can be tested in real dimension and test conditions with high precision. Also noise levels can be measured by the test machine. At the end of the study, real brake pad friction responses can be determined with fast and high precision by newly developed friction pad tester. The friction coefficient is increased rapidly at the beginning with the disc speed increased and the started to decrease and then continued constantly. From this, it is concluded that the whole brake pad pattern is related to surface contact and two interface resistances.
