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 4modification 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 is 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 is done by adding shims at the back of the brake pads and show the greatest squeal noise reduction. It is found also through the experiment that the disc brake squeal is significantly affected by brake pads structural geometry.
