Do we have brake override?

No "brake override" necessary. Just use your head.

Absolutely not. Never turn the ignition off and try to come to a stop. Without the engine running you're no longer producing vacuum, which your brake assist runs off of. No vacuum = no power brakes equating to pretty much zero stopping power.

Correct situation is to put the vehicle in neutral, let the engine redline, and come to a controlled stop.

If for what ever reason you lose power brakes, you still have the emergency brake. You just have to make sure you don't lock up the rear wheels.

No. The Yaris doesn't really need power brakes. And you can stop the car just fine without them. You *will* need to push harder. But your grandmother could probably lock all four wheels with the power disabled.

Being *surprised* by a lack of power assist could be a problem. Especially if you have other stuff on your mind. e.g. if you are coasting in neutral with the engine off and something completely unexpected happens, which requires immediate action.
