If the ABS was faulty and fighting him, or the power brakes failed, there is 0 chance for a human to stop a 3000 kg truck rolling down a 26° slope, even with perfect grip. Whether it has hydraulic or fly-by-wire breaks, if the electronics were faulty it wouldn’t matter.
I’ve had to stop my 2000 kg van from 110 km/h, on a relatively flat surface, when the ECU shat its pants in the rain and the engine died. Let me tell you, I weigh 80 kg, never skip leg day, and yet it took all my strength for a good 20 seconds whaling on the service brake to stop it (and yes, I made sure to let off a bit when a wheel locked). Add another metric ton or a steep hill and it would basically be impossible for all practical purposes.

… I mean, that’s not what I asked at all but okay.
Sure, sorry if it came off as rude, wasn’t intended that way
