I changed the back brakes, so I'm an expert on the Ebrake

It isn't the Ebrake cable I don't think, since I just finished the back brakes, and the brake has 2 cables that go from the weird thing in the car that you pull on to each of the back wheels. The 'cable' that broke should more properly be called a wire. A piece of crap wire that is sort of wimpy. I tested the brakes and the accelerator pedal and the clutch pedal, and it is not any of those things. What else can it be?! What suspense! I hope it lasts!

Is an emergency disconnect switch really important? My contactor (oops I should take a picture of it.... BAM, I took a picture) can break a LOT of current.

When controllers fail full on, do they fail at their current limit (400 amps)? Or do they fail as a short circuit (like 1500-2000 amps with these batteries). The fuse would kick in quickly, but if the controller failed at 400 amps, and the fuse didn't blow, and the contactor stuck at 400 amps (which it shouldn't), then and only then would I need an emergency disconnect. Could that happen with a probability greater than 10e-500? It would be an extra $24 to plug that nugget of badness.
