Combined brake housing
The combination of ABS/ESP housing and main brake cylinder enables brake operation and monitoring in the smallest spaces. This unit is an indispensable element for level-five self-driving vehicles and brake-by-wire systems. It reduces the braking distances in comparison to older systems and enables higher recuperation for electric vehicles. The integration of these functions in a single component boosts efficiency and safety in modern vehicle construction considerably.
