New techniques of crossdrilling on discs, advance in liner material are introduced to enhance brake performance and life. In this paper behavior of friction liner for light commercial vehicle is analyzed with help of CAE tools, also excitation of liner material under vibrating load and harmonic excitation of liner surface is studied. Modification in existing brake liner geometry is suggested through introduction of V-slots over curved surface of liner material. Reasoning behind providing slotted geometry is explained in due course of paper. Effect of modified brake liner substantially improve liner performance through reduced directional and total deformation of liner , also frequency analysis shows that effective area of total deformation is reduced with modified liners .Along with this, stress intensity across liner face is studied and results are compared with unmodified one , through CAE analysis it is clear that modified liners provide improved performance through reduced deformation and additional benefits such as improving brake cooling and providing de-gassing Copyright@ International Science Community Association
