Used Touareg and tow bars

[Marakai]

Hi all,

It's now been two months. We ended up buying the Touareg (dealth the previous owner down a bit more and got a really good deal over all). Are very happy with the car.

One point of confusion, though, remains: The whole electric brake complex.

The previous owner only ever towed trailers with hydraulic brakes. So he never had anything like a brake control unit installed. With the horse float having electric brakes, I'm totally confused: do we need such an extra unit or does a Touareg have one built in?

The reason I'm confused is that I've never heard of anybody in Germany (whence I come) installing such a thing, where a Touareg/Boeckmann combo is almost natural for transporting horses.

Have we been playing Russian Roulette and just *thought* the brakes are working when really, there's only the weight of the car keeping thing in check?! Or is there a default braking action being passed through the cable to the brakes and we are merely missing the "fine control" the unit provides?

Slightly worried now...

Yes you will need a brake controller. Don't know of any vehicles that have them built in. If his trailer had hydraulics he would have needed some sort of controller as well as you cant hook trailer and car brake hydraulics together.

A Tekonsha Prodigy or a P3 would be the best models although a Redarc Tow Pro is gaining popularity due to its small size.
Are easy to fit but care needs to be taken in a VW as to where you take the power from. A spare fuse socket is best and unit must have an 20amp auto reset circuit breaker in the power line NOT A FUSE.

Thanks, Hillbilly.

I had already narrowed down to the Tekonsha or the Redarc TP. The latter is also priced attractively.

Is this a DYI job or does it need a pro?

Speaking to the previous owner he was adamant he had never put any sort of controller in. Arguably illegal? Oh well, water under a bridge...

Its only 4 wires but they need to be done properly If you havent an idea of how its done it may be cheaper to get a pro or someone who knows rather than have a cloud of smoke LOL

Just make sure if you buy a Redarc its A TOW PRO not th eold crap model as there is a vast difference in operation and efficiency

Excellent thanks! What I like about the Redarc is that it's a nice simple control that can be nicely integrated into the Touareg dash. I wouldn't know where to put the Tekonsha without it "sticking out" or taking up some other spot. I definitely don't want it under the steering wheel or somewhere where our longs legs collide with it (we're both >6').

Marakai, the common terminology (hydraulic vs electronic brakes) used in Australia is misleading and leads to this confusion. Whilst the previous owner of your Touareg had hydraulically operated brakes, their system was activated by over-run. Car slows down, trailer over-runs car, compressing hitch, mechanically activating hydraulically operated brakes. You can also get cable operated over-run brakes. Our UK built Nugent float has this non hydraulic over-run system and I suspect this is how the Boeckmanns work too.

The rarity of what we term "electric brake" systems on floats in Germany is likely because EU allow up to 2.5 ton with the over-run system.

In Australia Over-run brakes may only be used on trailers that do not exceed 2 tons. Above 2 tons the brakes must be operable from the drivers seat, hence the requirement for an electronic brake controller to satisfy this.

To confuse things further you can also get electric, pneumatic or even hydraulically operated, "electric brake" systems!

The way I see it - the key point to note is that the need for an after market electronic brake controller is dictated by how the trailer brakes are activated and not by the system they use to function, be it electric, pneumatic or hydraulic. Practically speaking a trailer braking system will will either be over-run or Electronically activated.

Everyone fits electric brakes, but you might as well be aware of this statement in the brochures and on the VW websites:
"Please note Volkswagen does not endorse or will not be held liable for any claim, loss or damage arising from the use or fitment of electronic trailer brakes"
Just means if you stack with the trailer on don't bother trying to sue VW.

Have we been playing Russian Roulette and just *thought* the brakes are working when really, there's only the weight of the car keeping thing in check?

YES, just your cars brakes were stopping the lot. The float brakes were inactive.

We have two double horse floats fitted with over-run systems. One hydraulic the other cable. They work well.
Eventually we will upgrade to a heavier triple float. It will be over 2 ton so will require an electronic brake controller. until then out Touareg is doing a good job without it.

here are the rules regarding brakes on Trailers

Trailers that do not exceed 750 kg GTM with a single axle
No brakes are required.

Note: Where a trailer has two axles where the centres are less than 1 metre apart are regarded as a
single axle.

All other trailers that do not exceed 4500 kg ATM

These trailers must be fitted with an efficient brake system that complies with ADR 38/-. Except
for over-run brakes, all brakes must be operable from the driver's seat of the towing vehicle.

For trailers up to 2000 kg GTM, an efficient braking system is considered to have brakes operating
on the wheels of at least one axle. Over-run brakes may only be used on trailers that do not exceed
2 tonnes GTM.
Every trailer over 2000 kg GTM must have brakes operating on all wheels. The brake system must
cause immediate application of the trailer brakes in the event of the trailer becoming detached
from the towing
vehicle. Under these circumstances, the brakes must remain applied for at least 15 minutes.

I would have thought a double horse float would be at least 2000kg GTM But I could be wrong


If as Logger says you have overrides you do NOT need a brake controller An override hitch looks like this

Tow Hitches - Towing Equipment The top row are standard hitches

The left one in the second row $102 is an overide hitch so have a look and see what the float actually has.

I presumed, perhaps falsely that the float would be over 2000KG and therefore would need a controller.

Maybe the packhorse that rolled on me only felt like a tonne and wasnt really. LOL

It is common for a basic double horse float to weigh 850kg to 950kg. A Large horse such as a thoroughbred or warmblood can weigh 500 to 550 a piece. So up at the 2000KG limit but not necessarily over it. Many horse will come in under 500KG.
Our Nugent float is designed and certified in Europe to 2700KG with its over-run system, however until advised otherwise I treat is as 2000kg max.

The rules you are quoting are from the ADRs and whilst they are the rules, there are exceptions. For all I know the importer of my Nugent may have elected to have it certified as a "nonstandard" trailer. In which case they can go through a process to show the brake system is up to the task and have it certified to operate over-run brakes at the 2700kg in Australia too.
