The history of automobile brakes is about to take a turn as spectacular as it is unexpected. In Stuttgart, Mercedes-Benz unveils technology that shakes up more than a century of automotive tradition: a braking system integrated directly into the powertrain of electric vehicles. This innovation not only promises maintenance-free brakes for the entire life of the vehicle, but also a solution to environmental problems related to brake particles.
A technical revolution that defies the imagination
The new Mercedes braking system is radically different from traditional solutions. Gone are the days of external brakes attached to the wheel hubs. The brand with the star has completely rethought the concept of braking. The water-cooled disc remains stationary while the circular brake pad rotates with the motor. This unique configuration eliminates the need for the traditional caliper. Braking is done simply by pressing the circular pad against the fixed disc.
Benefits that go beyond maintenance
Mercedes’ promise goes far beyond practicality. This revolutionary system captures brake dust in a closed compartment, a particularly relevant innovation in the face of future Euro 7 European standards. These regulations, which will come into force in 2026, will take into account particle emissions from tires and brakes. Water cooling also eliminates the phenomenon of “fading” (loss of brake effectiveness under heavy use), while the reduction in unsprung weight improves handling.
Technology that addresses everyday problems
Mercedes is also tackling more everyday problems. Owners of electric vehicles can say goodbye to rusty brake discs after a few days of immobilization, a frequent source of complaints according to the manufacturer. The system also promises a significant reduction in braking noise. For designers, this innovation opens up new perspectives by allowing the creation of completely faired wheels, thus optimizing the aerodynamics of the vehicle.
Although the production date remains to be determinedthis innovation represents a significant step forward in the evolution of electric vehicles. It is part of the current trend among manufacturers to fundamentally rethink traditional automobile components to adapt them to the specificities of electric vehicles.
