The development of friction materials has traditionally relied on the use of empirical methods to satisfy performance criteria such as friction, wear, noise and compatibility with the brake rotor. Initially effort is concentrated on achieving good friction and wear characteristics whilst, due to the prolonged nature of the tests involved, consideration of other factors such as brake noise and rotor compatibility are usually relegated to the latter stages of the development program. Two measurement systems are described, one for the analysis of brake noise on vehicles and dynamometers, the other for mapping transient rotor surface temperature as an aid to assessment of compatibility between rotor and friction material. Examples and interpretations of data collected using each system are given and it is explained how use of these systems not only provides more rapid assessment of key performance characteristics but also increases our understanding of such phenomena so that their influence can be more easily taken account of at an early stage during formulation.
