1995 Defender 110 300 Tdi CSW Auto Keswick Green

My narrow track has had a simple bracket which extends beneath the handbrake to enable a breakaway cable to be fitted. I will post a picture later as it is a simple way to achieve this requirement. 1995 Defender 110 CSW

I'm not seeing a breakaway cable in that photo, just the brake operating cable (at least, I think that's all I am seeing). What applies the brakes and holds them on in the event of a breakaway?

I think if any single axle trailer breaks away from its main coupling it would be difficult to maintain any kind of control. Even if it it has a breakaway cable or chain it will very quickly start snaking and most likely spin over, it may be a legal requirement but I doubt it would be much use.

If any trailer with any number of axles breaks away you are likely to be deep trouble, but the idea of a breakway cable is that the brakes are pulled hard on so the trailer stops as quickly as possible, and the idea of a secondary chain is that it keeps the nose of the trailer following more or less the towing vehicle and discourages the drawbar from digging into the road surface and flipping the trailer. I agree that it is likely that the incident will not end well, and the trailer may well end up upside-down, but if the breakaway cable brings it to rest earlier, and the secondary coupling keeps it behind the towing vehicle and on the correct side of the road, then both are in my opinion worth having.

There have been too many incidents recently of rogue detached trailers killing people, and anything that we responsible drivers can do to reduce the likelihood is, I feel, a good idea.

^ Your right does not really show it that well

This is better the thinner cable with a carabina type clip on it. Zoomed in from the trailer as I bought it.

I'm planning on an extra chain with 'D' clamps also though

OK, thanks. I really couldn't spot that!

From your description, am I right in thinking that the trailer end of that cable is attached to the bell crank on the axle? If so, it really doesn't do the job since although the brakes will be applied momentarily, as soon as the cable breaks (which it is designed to do and inevitably will do) the brakes will release again.

The cable needs to be attached to the handbrake lever so that once the cable breaks, the trailer brakes will stay hard on.

The problem with the Sankey is that there is no obvious simple way of doing this, but hopefuilly Ramsey's photo, when he is able to post it, will show a suitable method.

Hello

My first picture is not the best and confusing

The breakaway cable is attached to the back of the handbrake with two strange looking connections, will take a better picture as want to make sure its right

In that case all may be well, but if you can post a pic when you get the chance we'll take a look and give an opinion!

I have the same thing on my MKIII Sankey the breakaway cable attaches to the handbrake mechanism which is on a ratchet so once pulled on needs to be released manualy.

Thanks for the explanation blackwolf I think I should maybe get a chain now as a further backup.

I have this setup but think will also add a breakaway cable attached to the rear of my hitch plate and onto the lower swing arm of the hand brake mechanism. When this pulls tight the brakes will apply. I will make sure that the length of the cable is less than the chain.

Have you a picture? Was it added at a later date?

^ that was my sort of idea as an extra saftey measure.

I have this breakaway currently is this attached correctly as I've done nothing with this but have a new cable ready to fit.

yes my thoughts exactly. At least if the unthinkable happens the cable will pull on the brakes (my ratchet handle doesn't really engage properly so once snaps may no longer engage brake) however chain will hopefully keep it attached to the Landy pending emergency brown-trousers stop!

Just make sure that pulling on the breakaway cable applies the handbrake ratchet so the brakes stay on.

I sold my narrowtrack some years ago (unfortunately) so am working from memory, but I think the lever your cable is on in the photo above is the lever that the back end of the lunette pushes on, in which case although pulling on the breakaway will apply the brakes, they won't stay on when the cable snaps. If so, this does not meet the requirement.

If I recall correctly you have to extend the handbrake lever itself downwards below the pivot on a narrowtrack in order to have a suitable attachment point.

Milestone reached. They are back together again!

Today finally managed to get some stuff done on the Sankey. Happy days. Chain hoist from Lidl did all the hard work!

Managed an hour today to do a few little jobs...

Used some Discovery mudflaps

Fitted ok, and should 'do the job'

Fitted my 8mm plastic cover plate to original number plate holder.

Then my kids School were throwing 3 large mats out.... I've used 2 for now in the tub. Will cut round the anchor points.

Still need to sort the wiring from 24v to 12v, I've decided to use a junction box so have one on order

OK so the job I've been putting off will have to be done soon as this turned up....

Nato 24v in one end and then 12v out the other.

That's the theory....

aarrgghh
