Stopping an LMDh car is just as hard as getting it going. Sure, they’ve got four brakes, but these cars are hybrids, which means you also have regenerative braking. Plus adjustments for engine braking. This makes everything infinitely more complicated for teams, drivers, and suppliers, and frankly, a lot more interesting.
Conceptually, the LMDh braking system is a lot like what’s used in Formula 1. The front brakes are purely hydraulic. But since the hybrid system is at the back, LMDh cars use a brake-by-wire system, Bosch’s Electronic Braking System (EBS) to manage the handoff between friction, regenerative, and engine braking at the rear of the car. Bosch also provides the Motor-Generator Unit (MGU), inverter, and control software for the spec hybrid system in LMDh.
