Question for Bking, TNUK's resident Mechanic/Fitter

Today I’ve been stitched up with trailer 26, it’s an M&G Curtain Sider, 2005 (10 years old) connected to my tractor-MAN TGX 26-440, 2013, 2 years old)

The ABS Light has been on all day (I know I should have left it in the yard, but I had a 10.00 drop in South Wales)
On the way back/empty, some of the wheels were
locking up.

When I get back to the yard I will park it up & refuse to take it out again, until it is fixed (PROPERLY !) our resident fitter will argue that they are not Compatible with each other & it’s not a problem !
My argument will be
“I wonder how VOSA/DVSA/GESTAPO will view it & my licence for taking a known defected trailer out on the road”

Question is-
Is our Fitter talking Sense, or is it BS ?

I’ve moved your question to the forum where I think it’s more likely to get the answer that you’re looking for.

Resident walloper more like

Brakes locking up can be due to mot brakes
Fitters increase the pressure to achieve braking performance

Well I wouldn’t let BKing loose on a bicycle puncture.

I do know exactly what is wrong and why it’s happening the answer is in my first post on the Amber ABS thread in the explanation for the reason that no ABS susie to an EBS trailer is an immediate prohibition rather than delayed.

I’II leave it and see if that’s enough of a clue for BKing to get the right answer.

He is talking bs All ABS systems are “compatible” what the hell would be the point of “incompatible” abs.

Even if you have an S socket fed abs system and a standard ISO coupling on the tractor your company should have a loop feed installed that feeds The S socket from pins 1 to 5 on the ISO lead.

Usually a 2nd ISO socket fitted to the A frame and linked into the S loop.

If you look on the trailer plate and the brake code number ends in a 7 or a K then the ABS must work before the vehicle goes out on the road unless it is pulled by a vehicle not equipped with ABS.Eg a yard shunter (terberg etc.)

The amber light is telling you the ABS is disabled.

Brakes lock up because the ABS is not working!

You really are full of it arnt you. Crap I mean

What the hell has EBS got to do with ABS ?

EBS has a lot to do with ABS but lets not jump the gun before we’ve got to the bottom of this little tutorial first.

Are you sure brakes lock up because the ABS isn’t working? Before ABS folk managed to drive everywhere without locking up all the time?

Here’s the clue, he said the brakes were locking up on the way back/empty. Now the loaded and unloaded weight of commercial vehicles is known to cause problems with the brake force applied so let’s draw upon your 40 years man and boy experience and see if you know what part might be put on a trailer to solve this problem?

I did that in post #4

Thanks Bking, I suspected it was BS, the fault is with the trailer, it’s a few years old, we’ve got a few more around the same age & I’ve often had ABS lights flashing on & the odd lock up, even with very gentle braking, especially in the Winter/wet/cold, maybe they’re in need of refurbishment (or ship 'em out to Africa). The brakes hav’nt been adjusted for MOT, it’s not due until August & our fitter won’t do any work on it unless it’s needed [emoji57].
I parked it up on Monday afternoon, telling out fitter that it was VOR’d, but a ‘Chimpanzee’ took it out Tuesday or Wednesday, so what more can I do. (I’M NOT TAKING IT OUT AGAIN !)

Sorry if I started an argument, every ones opinion differs a bit.

Own Account Driver-
Would that part that you are talking about be a Load Sensor ?
We’ve got another trailer (24) that locks up all the time when empty, just touch the brakes & it’s like a little Hiroshima behind you [emoji598][emoji297]️[emoji598][emoji297][emoji598]️[emoji297]️no ABS light in the cab, pretty sure that’s a load sensor issue. (Another one I’m refusing to take out, VOSA would have a field day !)

Honked-
No Glowing Star, sorry, as I said earlier, it’s not due MOT until August & I don’t reckon it’s seen a spanner since last August, it’s just a Knackered Old Trailer, on its last legs, ready for the scrap yard or Africa.

Thanks for all the advice.

The brake pressure may have been increased for mot and not reduced back after.
Does it do it with all units? That will tell you if it’s brake pressure or abs fault.

Think it does with other units, but a lot of our ‘Chimps’ just carry on & don’t even bother reporting defects, I’ll ask around next week.

Fit a new turbocharger before it all kicks off again!

Brake pressure increased?

What the( ZB )are you amatuers on about !

The brake pressure is controlled by the the load imposed on the air bags.
Glad I dont work for the cowboys you boys run for
Jesus.

Have you the slightest idea what you are talking about?
Of course the brakes lock up without ABS.
Thats the whole purpose of Anti Lock Braking Systems !!!

Your fitter is either lazy, incompetent, poorly trained or under the management’s thumb.

Haha you do make me giggle.
You can fool the LSV but there’s no fooling you.
