Yes, I know a camper trailer is a lot lighter (about 1300 kg) than a caravan or big trailer.

The idea of applying brakes to the trailer and not the towing vehicle, is to straighten the hitch point out and to do that you need the trailer dragging against the hitch...

Best description of this is when I had some goose wet a clay rump that I was using to enter a pit.... As there is a slight curve, my trailer decided to over take me and jack-knife... I applied full trailer brakes and full throttle at same time, this put me into a controlled slide as a single unit rather than a trailer just swinging behind trying to send me where-ever... I was able to steer and control that whole vehicle until I stopped, quite safely...(Mind you, I did get called Brockie for the rest of the day)... The point is, the hitch joint became a straight line between truck and trailer, thus my only concern after that, was pulling up safely....Ohh and lots of calming fluid required afterwards...

As I said before, swaying is the effect of the trailer having steerage control over towing vehicle... Its the trailer you need to sort out first to get control back to the towing vehicle...The towing vehicles job is to tow and steer the trailer not the other way around, thats called swaying... Thus brake trailer and you are now towing it again...


PS Ian just so you dont think I'm a rev head, The truck had an 8V71 in it... As you would know, two speeds, flat out or get out.. Loved the screaming demon but the ringing in the ears was a nightmare...

Thanks.
OK so in my case I would bang the vehicle brakes hard enough to make the display on the Tekonsha P6 show the maximum braking effort on the 1-5 scale and the trailer brakes would go to maximum effort, more than on the Defender.
But that's a different situation of course to yours.

Go hard or go home, even if you only have 318 HP. [bigrolf]
A mate's just done a medical etc, to drive an agi on site, even it's got 350 HP. :tease:

No Mick, that won't work because you'll have full braking effort on the Defender too. Slide the manual control without touching the brake pedal. Good luck with that for two reasons,
A- The controller is usually mounted in a relatively inaccessible position and
B- With only a couple of inches (if you're lucky) between off and maximum, it's difficult to operate with any degree of accuracy.
The mirrors will probably be filled with black tyre smoke, but if the tail's wagging the dog, a couple of tyres are cheap in comparison to a written off car and 'van, not to mention occupant safety.

A,= By law the manual control must be quickly accesable,, mines about 2 inches from my hand, and I practise, and its a good way to see how (if?) the van brakes are working,,
B,= accuracy?? if the tail decides to wag the dog as in the original video (remember that?)who cares? you actually WANT blue tyre smoke,,

but but but,, caravans are not supposed to be set up to produce lockup,,
(from the same people that brought you 10% ball weight)

The one professionally installed in the Paj is all but impossible to reach and see. I set the brakes high and read the road to avoid heavy braking.

Said it before and say it again , towing anything heavier than the tug is a recipe for trouble . I can not understand why anyone would want to tow a 3500Kg behind a 2500Kg pasenger vehicle .
I tow 1700Kg Jayco behind my 2007 RRS 2.7 and it feels about right , you can feel its there and the vehicle is heavy enough to be in charge in times of a bad situation .
As for sticking 350Kg on the tow bar of a passenger vehicle , well thats another story .

The days have changed a lot... I remember, with pride, doing the job with 400 gee gees, that you require a minimum of 500 + today...
Those that ran KT 19 at 450 where the power mongers, us 855's, 3406's and the V8's, running 400 where the majority of engines...

Last couple of jiggers had, 575, 550 and 650... Imagine what could have been done in the old days, with them...

But I have to admit one thing, those of old had to know how to run an engine, load, quote, fix everything and smooth over trouble on the job....

Today its, know the log books, get the paperwork right and know what forms to get the stereo or aircon fixed...

My last job was sweet, boss was more into old school workers and listened when I said something was going to break... Only complaint he had was, when I said something was worn out, I meant it... He asked me to get as much out of the clutch as possible, when we removed it, it fell to pieces, no cracks or breaks just completely worn away, springs in clutch plate fell out of holes completely worn away... Not bad for a truck pulling 88 tonne all day everyday for last 12 months with dicky clutch...

Good days Wraithe, I could tell some stories, but there's no statute of limitations in this country. [bigwhistle]

I once had a (single) trailer try to overtake me at around 90kmh near Ballarat. Black ice. A pull on the trailer brake brought the thing back into line. I still left the black top, but at least I did it without the trailer joining me in the cab.
