Brake Material Screening

Achieve Cost-Effective Development of Friction Materials

Bruker's UMT TriboLab™ Brake Material Screening Tester performs benchtop testing on small samples, applying comparable contact pressures to full-scale dynamometer testing.

The benchtop brake screening tests use small samples, applying the comparable contact pressures levels used in a full-scale dynamometer rig. The flexibility and range of testing capabilities of the Brake Material Screening solution rapidly and cost-effectively allows users to rank materials using protocols based on industry standards such as the SAE J2522 (AK Master), ultimately enabling the brake material industry to reduce development cycle times.

Speed Up Pad Development


Government environmental regulations and the industry demand for improved braking systems continue to drive the need for development of new formulations for brake pad materials.

While multiple formulations and process conditions could potentially meet these needs, full-scale dynamometer testing prior to on-road vehicle testing makes new friction material development both time-consuming and expensive.

Sample sizes for Brake Material Screening are considerably smaller, removing the need to construct complete brake pads of a potentially large number of candidate materials. By performing screening tests on small samples, but with comparable dynamometer test pressure, the brake material industry can effectively speed up development by selecting only the top few candidate materials to move forward for complete dynamometer functional testing, saving significant cost.
