Friction stability and wear resistance are key factors in brake system design and performance. The paper deals with the experimental investigation of friction characteristics and wear of three commercially available NAO (non-asbestos organic) disc brake friction materials viz. Grade A, Grade B and Grade C for a sport utility vehicle. The composites were evaluated for various friction performance properties such as average coefficient of friction, performance at various speeds (8.34 m/s to 38.89 m/s) and pressures (2 MPa to 12 MPa), fade & recovery behavior. These friction and wear characteristics were determined using four wheeler inertia dynamometer. The physical properties such as density, hardness, heat swell, water swell, adhesive bond strength at room temperature and adhesive bond strength at 400°C were studied according to Indian Standards.
