Downhill on wet hard clay can result in 100's of m with no brakes. However if you lock the wheels a wall builds up in front of the tyres slowing you. The more loose sand/dirt the better and as you get to harder surfaces it becomes more difficult but at least there is something as opposed to with ABS where putting your hand out the window would be more effective.
There is a good example of the slippery clay downhill in Midrand where Mane Rd enters the R562 as a T juction. I personally knew 9 clients that have died there and more than 20 people have died there. Most where towing horseboxes slowly approaching the junction, applied brakes and the ABS kicks in when it is wet. No brakes and enter the junction where the traffic across is doing 100 km/h. Yet there is enough loose stuff to stop you in time if you lock your wheels.
Had a classic a while ago when a client in an X5 was following me. I braked on a dry sand road for a corner without locking up. His ABS kicked in and he went straight and through a fence.

Is there a way of putting a manual override in to disable the ABS ?
ie: Like a switch to disable the system in the same way it gets disabled when the diff-lock is on in 4L ?
I guess I'll be chatting to Graham some time...

That's why for example driving in Botswana at night is not advisable... driving from Jhb to Mozambique ( I'm talking about the areas like the outskirts of Pongola and Jozini ) at night is not advisable. If you have to, be aware of your surroundings. Reduce your speed !! Look for eye reflections from the animals on the sides of the roads and even in the roads. An animal will more often than not freeze when a bright light is shone at it. I say this because you may swerve one way thinking the animal is going to continue moving in the opposite direction, but as the light hits it it freezes and looks straight at you all the way till impact.
Be safe out there !!!
