braking: both, recuperation is done on engine side, but there are still brakes at the wheels.

Recuperation doesn't cover all necessary brake performance, plus, you don't want to have a car without brakes at the wheels. The moment the driveshaft breaks, you wouldn't be able to brake your car, if braking was only facilitated by the engine.

This actually killed at least one race driver, Jochen Rindt, Monza 1970, in his Lotus 72.
