It doesn't have much to do with the quality of the brakes. In a road 
bike position on a steep downhill, you have to keep your ass on the back 
of the the seat but reach forward to the brakes and keep your head up. 
By steep downhill I'm  thinking well in the double digits range. One 
downhill that meets these details is the Cathedral Ledge access road in 
New hampshire.

The overall is only 10%, but there are long sections over 20%. The 
pavement is narrow and choppy with frost heaves, so you can't just let 
it go. By the time you get to the bottom your hands and wrists are sore 
from the death grip on the brakes. You have to stretch out to keep the 
real wheel on the ground, so your neck is sore from the extreme angle 
looking forward while on the steep downward slope.

Disk brakes won't heal any of that.
