[Which is why I said if there’s no air in the yellow line, you should recognise it when connecting it up. I know there’s no air in a Volvo yellow line, the older ones anyway, not sure of the new ones. Same goes for the 3 and early 4 series scania. But a driver should still be able to recognise this. It comes back to people knowing a little about what they are driving which is sadly lacking in some of today’s, only doin it for a wage drivers. It’s all very fine teaching people what to do but it’s much safer if they also understand why they are doing it.
Totally agree with you…all too often nowadays people just do things without really understanding why they are doing them. And whilst a little knowledge can be dangerous, so can no knowledge at all.

Well said…
Legs down are first on my list Villa.Even then after I’ve put trailer brake and uncoupled,I treble check that the bleeders are down.
You’ve obviously got the same OCD which I have when it comes to making sure the sods are down.

Cheers for this but unless I’m wrong, I cant see how this product can be used.
It would appear that as soon as the driver disconnects the red line, this system then applies the handbrake. Assuming the trailer becomes departed from the unit when going down the road, this means that the trailer handbrake would be applied and not the service brake. Handbrake effort can typically be half that of service brake so if a trailer were to come off then it is in everybodies interest for maximum braking effort to be applied via the service brake and not the handbrake. Will look into this product more at some other time.
Have looked into this product some more and it would appear that it does only work on the handbrake and not the service brake which is okay unless the trailer were to become detatched from the unit. Considering the amount of trailers which comes unhitched as opposed to trailer handbrakes are not applied, I dont really think that trailer detachment problems are much of an issue.

Try that with a Volvo, no pressure in the tellow line with the handbrake applied!
Correct me if I’m wrong but I thought that all modern day European trucks parked on the Yellow line? It was only the likes of the trusty ERF EC11 & co which didn’t.
Your Wrong
Scania and Volvo both have no park brake pressure on the yellow lead (Footbrake only)
Haha…I did some shunting work a couple of weeks back which involved shunting trailers between sites, sepatated by road, five or so miles apart. I was in and out of that cab like a rat up a drain pipe double checking all was ok You say that about checking the trailer jaws, I always do that now too.
Yep never used to worry too much about the pin in the jaws in the old days with spring suspension but now with air and doing the old down/up shimmy when hooking up I’m relying on my ■■■■■■■■■ technique on the air suspension controls, never had any complaints though but need to make sure the thing didn’t droop at that last moment and the tug test is never as good as checking your locked in the ■■■■■■■ properly.
Edit: just re-read this and any double entendres are accidental…

Please, ALWAYS apply the trailer brake when dropping a trailer.
If you don’t, you deserve to be sacked.
You could kill someone or put them in a wheelchair for ever.

Correction, the next driver to use the trailer will kill himself if he does not follow the coupling procedure correctly. On modern trailers, with spring lock brakes, there is no need to apply the parking brake, this is merely to try and compensate for the thick ■■■■■ who do our job just in case they leave the cab parking brake off in which case the whole lot is going to start rolling as soon as they knock off the trailer brake anyway.
I recall M & G trailers informing our service department that the parking brakes were for service purposes only, hence the silly design of the red buttons which makes it almost impossible to pull when wet as it has a useless lug not worth a ■■■■. It is only modern day health and stupidity that has brought this about and NOT the manufacturers.
It is not the person dropping the trailer who will kill someone, its the muppet picking it up who will kill himself. Lets look for someone else to blame though as that is the way forwards. Once again making excuses for the crap drivers out there who can’t couple up safely.

Just to add to this, just picked up a brand new dennison skelly and it is equiped with automatic trailer break which is applied as soon as the airlines are disconnected, when they are reconnected you then have to knock the trailer brake off.
No more roll aways if the unit handbrake hasnt been applied when the airlines are connected!!
Why dont they, like the air industry remedy the problem so it can’t happen again, they know that drivers are getting killed or injured by these type of accidents, and they know steps can be taken to avoid them, but they dont!!
you shouldn’t just assume, if your dropping a trailer the brakes automatically come on once red line is dropped, if split coupling dont just assume the bloke (girl) has applied the park brake, take responsibility and check yourself.
You say that about checking the trailer jaws, I always do that now too.
WTF?!?! lol
