Reduction of disc brake squeal noise through brake pad modification. Journal of Transport System Engineering, 7 (1). pp. 1-5. ISSN 2289–9790 (2020)
Abstract
One of the common noise issues in automotive industry is disc brake squeal. Many researchers conduct deep studies to reducing and eliminating disc brake squeal in the past decades. This paper proposes four modifications on the Malaysian national car brake pads to suppress squeal noise. The original and modified brake pads were subjected to dynamometer tests in accordance with SAE J2521 test procedure. It was noticed that the pad geometry modification reduced the brake noise intensity by 6% with the first modification, 12% with the second modification, 19% with the third modification, and 22% with the fourth modification. Additional modification was done by adding shims at the back of the brake pads and it showed the greatest squeal noise reduction. It was found also through the experiment that the disc brake squeal is significantly affected by brake pads structural geometry.
