Lets have a quick look at this in terms of the energy that your brakes have to convert to heat and radiate away
600 ft - 200 meters x 10 x mass in Kg - 2,000 joules per kg
60 mph stop - 27 m/sec - 1/2 x 27 x 27 Joules per kg - 364 Joules per kg
In energy terms the 600 ft is about six times as much as the 60 mph stop
In terms of "power" the 60 mph emergency stop should take less than 3 seconds - the descent would take what 10 minutes?? - 600 seconds
So the "power needs" for the descent are about one seventh of the braking needs
for a 700 kg vehicle we are talking about 85 kW for the braking and 12 kW for the descent
85 kW is a very very low figure for power dissipation of any modern disc brake system
I would NOT expect a continual 85 kW to overheat a disc brake system
The standard for a modified vehicle here (NZ) is that it should be able to pull the vehicle up from 60 mph - SIX times in a row without fading
