I don't want to sound stupid but how effective should electric brakes be.
I have a 1994 supreme getaway van single axle
I have the brake controller up full when brakes are applied I can feel the van pulling me back
My brother says they are not getting enough power and we tested them he said they should pull me up better than that at full power they should skid on a dirt road.
I adjusted the shoes all ok and same as before, both magnets are working
I have a brake controller a Tekonsha voyager powered by a 25amp fuse all fitted by a auto electrician
I will be talking to the auto electrician who installed the brake controller just wanting forum thoughts before and different opinion as I have not munch experience with electric van brakes.

Thanks Reilly

Reilly,
What does your bro do?
Unless he is an auto sparky or a brake technician, I would suggest that you take his advice with a grain or two of salt.
There have been problems with the "Voyager" brake controllers but usually with their interference with trailer lights flashing or doing other unwanted things.
The "Prodigy" is a much better controller IMHO.

Take it back to the auto electrician for his advice.
A wiring upgrade (bigger cables) would not do any harm as low voltages can create problems.

Hope this helps.

Disco.

hi there - My Jayco Flamingo ( about 1500 KG loaded) when i turn the brake adjuster up is can easily lock up on dirt and on tar - and when its turned right up i can even feel it doing the majority of the braking for both caravan and Patrol ( usually back it off if this is the case )

hope this helps

Hi,
Some of the new controllers only work under hard braking.They are fitted with a de-accellorometer,so the harder you brake the harder the brakes will apply.Try setting it at hard braking at 30/40 kph to lock up and then back them off a bit.
Cheers Guy

I've been adjusting my brakes on our former trailer, and now the caravan, to do 'their share' of the work only. That is, if I flick the lever of the Prodigy right over on my customary mid-range volts setting, you can feel the van tugging 'with purpose' on the car. That's all. If you get those electrics working too hard on higher voltages you'll probably end up with very hot van hubs on windy/hilly roads.
PS: I used to run the camper on 7 volts - the 4 wheel van now wants only 5 volts (very same controller) for the same braking 'contribution'.

Like those above, my trailer would lock up on dirt if vehicle was braked hard, and on tar if braked very hard, however the brake controller unit is easily adjustable from drivers seat, so I could set it not to lock up fully, depending on the surface and the load.

No good having trailer/van push the towing vehicle further along the road, dirt or tar, when the vehicle brakes, and the trailer is NOT braking with same/similar force.

I have traded my Forester for a Pajero and upgraded from Tekonsha Voyager to the new Tekonsha P3. The new P3 is a vast improvement over the voyager.

Ideally, the caravan brakes should do the braking for the caravan so that the caravan is not felt 'pulling' or 'pushing' the car - in other words, your pressure applied to the brake pedal should be the same as if the caravan wasn't there.

If you find yourself having to press the brake pedal harder when towing the caravan, the caravan isn't doing enough braking. If you find that you need less pedal presssure when towing the caravan, the caravan is doing too much braking (ie. doing some braking on behalf of your car).

The Teksonha brake controllers come with instructions for how to set up the adjustments properly.

It seems common for electric brakes to take a bit of warming up.Mine take a good 5km of suburban driving, or about 2km of pumping the brakes for them to become effective.
I usually have the controller adjusted up for the first few km.s then adjust them down after I feel the van brakes pulling on the car. I have a prodigy controller so, while having to adjust them if I want them to be effective straight away is a bit of a pain, it is a simple job with the prodigy.

I think the problem may be in the adjustment of the brakes. Our van (20 foot dirt road) has just been serviced, which included a brake adjustment. Prior to the service, the the brakes were very effective at around mid range power, and the Prodigy controller never needed any adjustment (after the initial one) between or during trips. After the service I have very little braking even on full power. In my case I am certain that the brake adjustment has caused the problem, and as you have just adjusted yours, maybe it is in your case too. I am going to try readjusting mine myself to see if I can restore the effectiveness.

I'm going to replace the shoes they are past 3/4 of there use then will see how it goes the sparky suggested this before making any changes or follow up will be doing that in a couple of weeks.


Thanks for everyone's input, I have learned alot

Hi Reilly,


I wrote a lengthy follow up which has somehow vanished. Brief summary follows.

The Disco 2 is a great tow vehicle. It is also the most comfortable long distance touring vehicle I have ever owned, and I have had some very nice cars during my working life. Mine has a 4.6 litre engine versus the standard 4.0 litre V8. Same engine essentially, but with a longer stroke crankshaft. It uses no more fuel than the 4.0.

On the highway I get around 13 LHK at 100-110, but that goes up with the van on the back to around 24 LHK travelling at around 85-90 locked in third. The V8 power and torque curves mean that to travel at that speed you need to be in third. To stay in top you need to be at least 100kph, and I find that too fast on country roads.

With the standard tank you need to plan in stages of around 300 km, which gives very little flexibility in where you buy fuel. I fitted Long Ranger tanks to mine, which ups fuel capacity to 163 litres, which is great.

The Disco 2 is rated to tow up to 3.5 tonnes with up to 250 kg on the tow bar. Our van is a 20 foot Sterling Outback, which weighs a bit over 2.5 tonnes loaded and sits pretty high.

The Discos suspension and brakes are outstanding with a heavy van. I fitted Poly Air springs to my rear coils, so I doin't need to use a WDH, but I do because it smoothes out any pitching on undulating roads.

I love my V8, but if I was buying now for caravan use I would almost certainly go for a diesel, as they are clearly better for towing. Hope this helps.
