: This paper presents the systematical approach to generate lab test mode using a brake dynamometer to estimate performance drop of brake pads under the circuit driving condition. AUDI R8 with cast iron disc brake system is used as the reference vehicle. Brake pad performance drop is characterized by driving vehicle on F1 circuit, performing a subjective and objective evaluation of the brake performance, analyzing the evolution of the significant parameters related with brake performance drop. Taking into account all the data and information gathered in vehicle test, a well correlated brake pad lab test mode is developed.

Drum brake is a braking part which is widely used on heavy truck. The distribution and dimension of contacting pressure and contacting area between friction linings and brake drum have important influence on braking performance. Entire contact theory in this article was found based on the conditions that the outside radius of linings was equal to the inside radius of drum. The relation between the corresponding points on contact surface and the angle which lining rotated around support pin axis was calculated based on entire contact theory. The radial deformation, pressure distribution, contact area of linings and the brake performance were analyzed in the condition of entire contact theory.

Braking Process

Brake pad and disc design are important factors in ensuring excellent brake performance. But, particles from the environment can easily enter and interrupt the braking process and reduce braking performance. Friction depends on the design and surface properties of the pad and the disc. Wear happens in the brake system as the pad and disc try to withstand the braking force during the braking process.  An experiment using brake dynamometer is done in order to determine the design effects on friction and wear when hard particle are present during the braking process. The test used three different brake pad designs under medium sliding load condition. It is found that Design 2 with a middle line groove provides better and stable brake torque and friction performance compared to Design 1 and Design 3. Design 2 also gavethe smallestweight loss inthe wear analysis of the pad.

levels. In joints with simulated acute effusion the effect of position on IAP was dependent upon the volume of fluid in the joint. The results indicate that dynamic pressure levels in the moving knee are related to the movements of the joint. The characteristic and reproducible patterns of pressure may reflect changes in the structural configuration of the joint capsule and surrounding tissues during movement, and are influenced by the amount of fluid in the joint.
