Abstract
The influence of the pad contact surface deformation for vehicle brakes on its frictional behavior and friction induced noise is presented in this paper. Friction composite samples of organic binder-type brake pad have been curried out at 17 MPa and 180 °C for heavy-duty applications. However, samples with different surface shapes (solid, drilled and grooved) have been formed and tested tribologically to satisfy suitable friction coefficient at low noise level. A FAST machine was used to find out the accurate friction response at steady frictional moment. Friction acoustic noise has been carried out on the test machine using the sound pressure level meter. Analyses of the obtained results showed that the feature of the pad material surface has a significant influence on the brake frictional stability and noise emission. The results also confirmed that; adding a groove to the brake lining in heavy-duty vehicles gives a better brake performance and hence it is highly recommended.
