I Think the dampener has gone on my 16 month old tt3622 tipper

Towing the dx10 tonight shunting me a few times on harder breaking but not on normal breaking

I tow it most days but often not loaded with much more than 1 ton so 2.2 gross.

Seems a bit s**t to have gone so soon

Anyone else had one go or have it bumping through hitch

Are you sure the brakes are set right? It’ll crash and bang if there’s no resistance from the brake cables. I’d start there.
They were fine I’ll whip wheel off check brakes see if they’ve worn

I'd just get the wheels in the air and wind up the adjusters first, 'til they're just about to nip and give it a try ..... don't have a lot of faith in auto adjusters ;)
This x100. Ifors are knott axles, so not auto adjusters. If you use an Ifor regularly they really need adjusting once a month at least. It’s a two minute job.

If the handbrake doesn’t engage at under halfway through the lift cycle then your brakes aren’t set right.

I’m guessing you’ve never adjusted the brakes. I’m 99% sure this is your problem. Make sure you nip the brake shoes up on the drum nut before touching the cables.

Accepted practice is to nip it till they lightly bind, then back off half a turn. The shoes will likely still rub slightly. Then check you cables, either by pulling with pliers underneath or have someone activate the handbrake. You want 3-5mm of free play.

Towing it almost daily for 16 months, I don't think brakes or damper worn out is that bad.
Try seeing how far the hitch compresses in, or how far the hand brake travels, it will give you an idea of brake adjustment, again pushing the hitch in, it should be under a constant resistance and return slowly if the damper is OK.
In extreme cases of worn damper, the constant banging of the trailer on the hitch, can cause fracturing of the ball hitch, leading to failure.

Doesn't sound like damper failure when they go the trailer gives you a good kick as soon as you think about breaking then comes off and does it again.

Id try adjusting the brakes free moving of the cables is important it doesn't take much drag to mess up the breaks
