| Summary: | This paper investigates the effect of water absorption in the brake pad on squeal noise occurrences. A series of brake noise tests is performed at different hydraulic pressure and rotating speed conditions using the laboratory brake test rig, Four brake pad conditions are examined and tested, namely dry, low water absorption, medium water absorption and high water absorption, The test results show that the dry brake pad produces fewer numbers of squeal occurrence compared to the other three wet pad conditions, These three wet pads are also generating high sound pressure level, i.e. 100 dBA and above. than that recorded by the dry pad. |
