A car's brake has been pertinently termed its “conscience”. For a vehicle to have clear conscience would mean that its brake system continues to function perfectly, even after long running periods. This stands specifically for the pads and linings which take directly part in the transformation of energy. For an easier choice regarding temperature-sensitivity a method has been developed to calculate the brake rotor temperature for various driving cycles. Together with the function of the friction coefficient which depends on brake rotor temperature it will be shown, using the friction-coefficient-scatter diagram (1) how the sequence of locking might change. It will be explained how an unfavorable choice of pad combinations can adversely affect the braking stability and traffic safety.
