There is a difference between the engine overcoming the brakes, and the brakes overcoming the engine. If the car is already stopped there is no momentum on the rotors, fully apply the brakes and you get a great amount of static friction, then go to WOT and the brakes will probably hold. Now if you start with the car in motion at WOT, when you apply the brakes there is a large amount of kinetic energy to convert to heat in order to stop the car, and the hotter the pads get the less effective they will become. So I think it would very much depend on the situation whether or not the brakes will win.

Precisely.

Is the butterfly plate even in there? At first it looked like it was closed, but now I'm not sure if there is even one in there.

Shhhhhh.
No screws in the pivot pin, either.

Did anybody read the AP story on Toyota's blackbox cover up?

When Toyota was asked by the AP to explain what exactly its recorders do collect, a company statement said Thursday that the devices record data from five seconds before until two seconds after an air bag is deployed in a crash.

How do they know a crash is coming?

Now read this,

Before she died, the 5-foot-2, 125-pound woman told relatives she was practically standing with both feet on the brake pedal but could not stop the car from slamming into a building. Records confirm that emergency personnel found Grossman with both feet on the brake pedal.

Before she died? So while she was fighting a runaway car she called someone and explained all that and still managed to keep her feet on the brake pedals after she died.

Probably no write over of that data space.
Flag stop.


I don't think she was moving around much post mortem.

There was an ABC video in Feb of some safety engineer was was able to stimulate this fault condition, actually induce a short causing sudden acceleration in the electrical system, and the onboard sensors did not pick up a fault at all. That video may have already been posted here and discussed, since it was right around the congressional testimony and it came up that day.

I had a 77 impala with a butterfly value (and drive by wire). That used to stick open too, and I would have sudden acceleration and I would usually have to pull the accelerator back up with my toe, or shut the car off. I would get out and spray some 10w40 on the throttle cable.

looping buffer. I work with data acquisition systems all the time.
