Brakes on Autopilot Cars

Yes.
The braking system is still hydraulic, with the typical dual master cylinder driving conventional disc brakes.
However, the booster is now electric. Tesla appears to be using a version of Bosch's iBooster system - there is an electric motor geared directly to the master cylinder piston, which can apply boost (or apply the brakes without the operator) at any time, using electric power to pressurize the hydraulic fluid in the brake system.

The new system has several advantages over the old, including:
1. Improved pedal feel. More immediate grip. Not mushy anymore. Feels more BMW, less Lexus.
2. No more vacuum pump, since the brake boost assist is now electromechanical. This means no more vacuum pump sound, which I found loud and annoying.

Thank you both. That was precisely the type of info I was looking for!
