Abstract:
This report outlines the development of a testing apparatus for evaluating the frictional characteristics of light vehicle brake pads, including parameters such as brake pad wear rate, disc temperature, and average disc stopping time. Quality control and product validation are essential during the product development phase. Various input variables, such as speed and pressure, were applied to assess the impact of contact pressure on brake pad wear and the influence of speed on brake pad wear, disc temperature, and average stopping time.
Two sets of brake pads, namely pad1 (Semi Metallic pad) and pad2 (Ceramic pad), underwent testing. At maximum disc speed (1400 rpm) and contact pressure (0.8 MPa), pad1 exhibited a wear rate of 4×10-4 mm, while pad2 recorded 4.12×10-4 mm, both of which were lower than the 5×10-4 mm reported by Blau in 2001. When contact pressure was varied, the wear rate for pad1 and pad2 at 0.8 MPa was 3.9×10-4 mm and 4.0×10-4 mm, respectively, and at 1.4 MPa, it increased to 4.3×10-4 mm for pad1 and 4.4×10-4 mm for pad2. It was observed that the wear rate increased as brake applied pressure increased. Additionally, the ceramic brake pad (pad2) exhibited the shortest average stopping time. Analysis of the average disc temperature rise at different speeds indicated that pad1 had a higher temperature increase compared to pad2, establishing pad2 as the superior brake pad option.
