Evaluation Of Contact Pressure And Speed On The Wear Rate And Braking Effectiveness Of Automobile Disc Brake Pads Using A Locally Fabricated Test Rig

Abstract

A locally fabricated Brake Pad Test Rig was successfully used to evaluate the wear rate and braking effectiveness of two samples of automobile disc brake pads at various speeds and braking forces. Detailed design analysis of the test rig, which was also used to determine the average stopping time at a constant pressure of 10bar and subsequently, a constant speed of 980rpm, is presented in this work. Results obtained from the performance test carried out on the rig show the functionality of the test rig. Keywords: Automotive Brakes, Test Rig, Brake Pad, Wear Rate, Braking Effectiveness
