I would be using an exhaust brake which I would activate after decelerating and selecting the appropriate gear, very occasionally on long hills on the road but mainly in low low in the bush, we have some very long decents around here and she can start to get away from me unless I ride the brakes a bit and that can get interesting too but I know how to keep that under control.

NOOOOOO...

no using exhaust brakes in low range off road.... BAD.. do not pass go, do not change gears do not expect to maintain traction when you stomp on the exhuast brake in low range and the engine suddenly decelerates the wheels so fast they let go. Do expect the front short axle to give way if you try this loaded and skip the front end.

I might make an exception for low 4/5 but thats it... if your engine braking isnt enough in the bottom gears then you assist the engine braking by modulating the foot brake..

try that on if youve got a trailer pushing in low box and you can almost certainly expect the rear axle to want to be somwhere other than uphill of the front axle.

Even on the IMV drivers course they teach that you punch the first gear button, hit the brakes to make sure that its actually in 1st then turn the retarder off for descents.

Very interesting posts.:)

I always use engine braking on the SIII, never occurred to me not to. Not that I wouldn't trust the brakes on the SIII, oh no, of course not (where's the sarcasm button!).:D:angel:

Thank goodness for engine braking on the Series III.

I still haven't forgotten the thrill of coming out of Bendethra in the Series III. After driving through the river at the start of the climb, I rode the brakes until they were dry. I tried them a couple more times and they felt good, so I thought no more about it until the first steep downhill bit. I had no brakes in spite of the fact that they had appeared to be well and truly dried out.

Lots of engine braking, white knuckles and adrenalin later we reached the bottom of the hill safely.

:Rolling::Rolling::Rolling::Rolling:
Yea, I can relate to that!

That's one thing they did get right, the SIII has REALLY good low gear ratio!!!

Never drive a SIII expecting the brakes to work :o:D

Allan, I say thank Christ for the Spoon Drains, lost the brakes (fluid boiling, crappy old fluid) a few times on Mericumbene and Dry Creek, without the spoon drains I'd be dead now, Regards Frank.

OK, amidst all this talk of fitting Jake brakes to 4WD's, of which there is really no benefit unless you've suddenly developed a GVM of 20 tonnes between going shopping and walking back to the carpark, may I remind people, as it seems to be the last thing that anybody seems to think of, just watch all those American TV shows with cars spearing out of control down hills, that there is in place, operating independently of the normal brake system, a little thing called a
HANDBRAKE!!!!!!!!!!

FFS!!!

:p

Hi ,I drive a B double most days ,carting loads in excess of 50 tonnes,I travel down the toowoomba range nearly every day,the engine in my truck is a caterpillar ,I can come down the range in second intermediate ,in a eighteen speed fuller box,and never have to touch my foot brakes,the engine brake can hold me back all the way down the range,at the bottom my brakes are cold as...that's how good engine brakes are,best thing ever invented.........In trucks thy are a god send...keith:angel:

remind me to make sure that I am behind you in convoys...


I dont want to have to crane my neck to take pictures of the result of you trying that particular little trick on a long winding descent when you realise you have no real brakes left as you approach a hard turn at 50 with a trailer on, especially if youve been out playing in clay and its raining.

A hard turn at 50??? I had my hard turn at 34 when I got divorced, then it all got better from there......... oooooooooohhhhh you meant 50KMH hard turn... No problem Dave, I just flick the "Carlos Sainz" switch on the dash and everythings sweet!!!!!! :D:p

you could...

But i didnt think he did it with trailers on so the software that the switch controls wont compensate for it...

If you like I can get you some explosive bolts that you can wire up to the switch so that when you hit it it kicks off the tow hitch allowing the software to function unimpeded....
