There is a big mis-conception on what regen brakes can do. First off, a battery is not a big sponge that can accept electricity at the full rate, at all times. When the battery is nearly topped off or when it is cold, it can take NO charge. As the charge in the battery approaches 90% or more, there is little regen. So, for those instances, the hydraulic actuated disk brakes do all the stopping. Rest assured, the OEM Tesla hydraulic brakes are very robust. If one opts for the performance "Plaid" models, they are even more so. In addition, a track package is available for serious users that uses aluminum forged wheels, Track-ready tires, special hi-temp brake fluid, carbon-silicone carbide rotors, and one piece forged calipers with hi-performance pads.
As for the electric disk brakes; A Tesla has no transmission and no place for a parking sprang. When you stop and open the driver's door or select "Park" on the screen or console buttons, the electric actuator in each wheel applies pressure to the brake pads to keep the vehicle stationary. It serves no purpose in bringing the car to a halt while driving.
