On the after-race show, they said something like the brakes now depend on the electric systems, and if these fail (and they did), only the front brakes work as a back up system - or something like that, I wasn't paying too much attention.
If you see the footage, the smoke really does come from the front wheels only.
Brake by wire for the ERS. The rear brakes have no physical (hydraulic) connection to the pedal.
