I have dealt with 1 modern-ish/heavy car that stalled its engine on a downhill slope and my braking ability in this case was reduced to a mere suggestion. If you are strong enough to bring down an unpowered 4000lb+ vehicle to a complete stop on a downslope, more power to you but it is a bit unfeeling to assume that everyone shares your extraordinary pedal-pounding strength. Edit:s/freakish/extraordinary.

4,000lb Toyota LandCruiser with drum brakes and no vacuum “power assist” enough of a test?

You have a tiny master cylinder compared to a vehicle with power brakes, so it should work fine... this is different than having a big master cylinder + power brakes disabled.
