After one hundred years of wheel brake development, future innovation for the advancement of the mobile society and automotive industry will be shaped from global megatrends. Each future solution must also offer their contribution to stable emission and fuel consumption, safety as well as simplicity during production and operation with justifiable mobility costs. In order to improve the CO2 footprint, consumption must reduce. The hereby contributed possibilities for weight reduction in the brake system and pad are not exhausted by far. The reali-sation is however only partially achievable if restricted to individual components. The full po-tential requires early intervention in the weight optimised design of the complete system. Regenerative brakes in current electric and hybrid cars are not designed to replace friction braking. On the contrary, to secure safety in emergency situations and to provide the shortest stopping distances, the friction brake is still today the only reliable solution. But with growing quantities of electric and hybrid cars on the market and having solved to-day's problems of energy transformation, onboard storage and brake blending, brake systems with optimised friction pads will be requested to respond to the changing operating conditions of friction brakes. These challenges will lead to a change of the friction pair's properties. The reduced energy requirements and consequently reduced temperature level of the friction pair, in combination with very high and respectively very low rubbing speeds is a significant factor for the design and development of friction materials for hybrid brake systems. These altered load conditions result in new design and optimisation possibilities of the brake system and friction pair. Emissions of brake dust will stand more and more in the spotlight of future developments. Primary concepts for the avoidance of wear debris offer the greatest effect here. The presented regenerative friction principle points a way there. Beyond that it offers attractive possibilities for reductions in wear volume and weight.
