Steep downhill control of an RB30 Patrol

[PeeBee]

If you mean what I think then that technique is known as 'cadence braking', very common in colder climes where ice etc is an issue, Europe, Canada, US.
Can be quite effective with experience but must admit I have never came close to mastering it
I think it is still taught in the ADF but not sure.




Jeez dude... that is more than just a tad dangerous thing to be doing IMHO.
An old school 4WD saying is "your right foot may get you there if your left foot doesn't kill you first" meaning you should NEVER be 'clutch in' on a steep ascent/descent

Why wouldn't you attempt the challenge in the correct gear and just turn the ignition off if the speed gets too high and then do a stall recovery technique?
Even if you did it multiple times you would get to the bottom of the challenge without having ever lost control of the vehicle or shitting yourself.

In my Petrol 'Cruisers and MQ Patrol days thats what we would do and indeed is still a basic technique in both Diesel or Petrol vehicles on 4WD courses.

Clutch should never be disengaged on descents, simply asking for trouble. Agee 100% with what ET says above. When I had my 2.8td engine, same problem as Muddy has, so I dropped in a set of marks 85% gears and fixed it, but this is not an option, so just feather the brakes and start slow.
