The application of disc brakes on a large bus is more and more. The development of a brake pad with high performance and environmental protection for a bus has important social significance and economic value. The effects of the hardness of friction plate on brake noise was studied experimentally. The results show that the hardness of friction plate has a significant influence on brake noise, the lower the hardness, the more difficult to brake noise. The green raw materials with high quality were chosen, a formula of friction plate was optimized by using quadratic response surface regression mathematics models, a brake pad with environment-friendly was developed. It is verified that the developed one has high stability friction coefficient, low wear rate, and it brakes noiselessly by brake noise and friction performance test. The road experiment for the developed one was carried out. The results indicate that the average service life for the developed one improved significantly, the front wheel by about 59%, and the rear wheel by about 74%, compared with the auxiliary brake pad.
