Have had the heart beat way above normal this week, as i have had to take the ute down a shocker track to get fuel to the machine where i'm working. Its steep, wet ,and all things nice, for a 4by, but have tried a few approaches, the first day second low with centre diff lock in saw me amble about half way down, then the weight took over and the thing just took off no stopping it !, missed a few trees and luckily ended up in a paddock down below. ( no cliffs thank gawd!). Next time around
i pulled the handbrake on engaged low low and actually used a bit of acelerater to drive it, worked a lot better but it was fighting all the way. if you had a situation where there were drop offs either side, and its that wet you can't stand up with out slipping A over Z, then my advice is..... DON"T go there.
Cheers Axle.

That's what what I use mud chains for, a safe controlled decent.

A frequent problem in the Victorian High Country Axle.
Nothing much about 4WDing bothers me except steep (and I mean _steep_) hills!

Going up with centre diff lock in was a struggle, but got there, Kev. ( After all its a defender lol) Its the weight of the vehicle wanting to push when going down is the problem.

It's a timely subject, and I suspect it's defined by what an individual considers steep.
I think Axle's talking about a run away vehicle down a steep cut bush track.
Once a car gets up enough momentum, you can kiss technique and car technology goodbye. In my time it's happened a few times and been a bloody frightening experience.
A few of you would probably remember the
young couple who lost their lives on the
hill track near the
ruins in the Wonnangatta a few years back. And was in the dry.
As a fuel distributor in Gippsland back then, we lost a couple of trucks in the High Country because of poor driver judgement.
Same thing happened when I was running a business in Tassie delivering fuel to loggers. I was for ever telling the fellas to take care.
I think rather than rattle on about braking (by what ever means) give a bit of thought to what your taking on. Things can go pear shaped pretty quickly during the winter months up in the High Country.
Regards
Kim

Hey Axle
"after all it's a Defender" ... not the same Defender I saw bogged in a back yard in suburban Berkeley Vale?? It was a noble gesture, though, assisting the
young lady in distress. How did the
young bloke get on with his Hilux/Commodore motor?

Sorry, Axle.
At least I didn't mention being pulled out by the old Hilux!! Oops.
Well at least you had a go. Wasn't game to take
mine (
well actually the wife's) in there. Glad the
young bloke's great truck is ok, shame to be a good samaritan and stuff up your own gear.

If your hand brake is on the transmision shaft then definitely do NOT use it. Practice your left foot braking and keep the handbrake for emergency use only.

NOPE!, Diisagree, thought about this and touching the brake pedal when in wet conditions is just suicide. because therei is always one wheel that will lock up first and then the trouble begins.

Kiwi Kia might be talking about driving "through the brakes" rather than using your left foot to apply the brake AFTER moving. Basically you are riding the brakes HARD - backing off the accelerator stops the vehicle. Very slow controlled descent.
Mind you if the vehicle simply starts sledding down the
hill....! Haven't had it happen to me yet but I imagine the best thing to do is release all brakes to get steering back - and pray!

Axle, Scubaroo is almost right.
You need to learn how to do left foot braking. Imagine you have an
orange taped to the sole of your shoe, gently push down on the brake without bursting the
orange and then maintain this slight pressure whilst using your right foot to push the accelerator a little to move the vehicle forward. This method is also known as 'drive-over brakes' or as Scubaroo says driveing 'through the brakes'. The brake pressure required is more a retarding brake to stop the vehicle running away rather then a holding brake. If you have a limited slip diff then this method can also be used as a poor man's diff lock, the gentle braking action locks the lsd while the accelerator continues to move you forward. Yes, it can be done with careful application of the handbrake IF the handbrake is on the
wheels and NOT on the drive shaft.

thats ok when some traction is available at some stage, but go back and read KIMS REPLY, Theres no substitute for experience.
Kiwi Kia, What you say will work only under certain conditions!;
Putting your left foot, right foot, on the brake in diabolical conditions and trying to drive at the same time will make no difference what so ever, if the thing breaks loose, and when on wet red clay down
hill the weight of the vehicle takes over . As Kim said no driving technique will save you.
Cheers Axle.

Classic Axle,
I had a little adrenaline experience with mud on Tuesday arve...... Same deal, ute got away from me and slid into the bank.... only bent the back light.
Was glad the site's workshop had a gurnie. Wheel balance was a struggle to keep on the road. really didn't want to drive the 3 hours south back to
Sydney.
But it is all in good fun eh :)

I hate that situation. My paddocks are like that now.
Theoretically you accelerate to catch up with your slide speed.... I don't think I've ever had the guts to do it properly.
A week ago, I towed a trailer with cattle into the paddock [not very steep] and found myself turning around as the trailer started to pass me. Didn't do the fence much good when we hit it side on.
I unloaded the cattle, unhitched the trailer and drove out, diff locks on. The trailer might stay there til Summer I think!
Cheers

One of the basic's in 4x4 driving is use low range first for steep/slippery descents to keep the speed and momentum low. If there are any ruts, keep your
wheels in them (Within reason) to use them to guide you down the slope. If the
wheels start to slide from the compression breaking, apply just enough throttle to get things under control (and tighten your sphincter! ).
Be very careful feathering the brakes. If the
wheels show any
sign of locking up, immediately release the brakes.
If it is very slippery and dangerous and you MUST get down, then drop a tree and tie it behind the vehicle to assist in the breaking. This should only be done in a absolute emergency and avoided if at all possible.

Hi StephenF10, Im still cackling thinking of that reply LOL LOL I can just picture it. Mr Pointyhead, on a serious note now I have wiped the tears from my eyes, You say "If the wheels show any
sign of locking up, immediately release the brakes" excuse my ignorance as I have not had a 4wd with ABS before, would there be anything different to do in this situation,Senario, say if Im heading down steep
hill, (auto/petrol) locked in first, foot on brake to slow it up, slipery conditions and pedal starts to pulsate because the ABS is activated ??? What would be the best option ?? Keep foot on brake and let ABS do the work (if it does) or apply pressure to handbrake ?? as
well. Is ABS deactivated when in low range ?? (nothing in log book about that).Regards steve M

Never tried this but has anyone jammed foot on brake to lock wheels and then whack in reverse and then put the right pedal to the floor??
I know easier said than done........and when you start sliding and the fear hits most people would just freeze.
Axle, want to try an Aussie version of Myth Busters and try it out for us??? ;)))
