PROTON-Faculty of Mechanical Engineering, UTM Research Collaboration Project: Brake Squeal Noise Suppression
December 2017

Brakes squeal has remained to be one of the vital Noise, Vibration and Harshness (NSH) challenge in brake system design and development. It has been a concern for the automotive industry for a decade. Brake researchers have proposed many brake squeal reduction and prevention methods to overcome and reduce the squeal that emanates from the brake disc systems. In this research project, the effectiveness of constrained layer dampers (CLD) in lowering disc brake squeal noise is investigated. CLD isolates the brake squeal noise through shear deformations of the viscoelastic materials. This study aims to examine the effectiveness of Constrained Layer Dampers (CLD) in reducing brake squeal occurrences at different hydraulic pressure and temperature. Dr. Abd Rahim Abu Bakar leads the project and supported by Dr. Mohd Kameil Abdul Hamid, Dr. Nurulakmar Abu Hussain, and Mr. Khidzir Zakaria.
