From other threads I have read that a few of you have replaced it. I was wondering where you bought it from and how much it cost you?

Just heard back from vw heritage and its no longer available. Already tried vw uk. I would have thought somebody would be able to rebuild them. Anybody have any ideas on that one?

Have you tried Euro Car Parts
They recently sourced me an ATE master cylinder from Germany.
I wonder if they can do the same with the "booster"
Actually it's a retarder!
It stops the rears locking up under light loads.

Mecatechnic might be worth a shot, but I suspect, like VW Heritage they get their parts from http://www.vw-classicparts.de/

I've been in contact with classicparts.de previously and they will communicate in English. Very helpful in fact, even going to the trouble of taking a photo of the part to confirm it was the right one for me.

I'd have thought one of the companies who rebuild brake calipers would be able to recondition it if needed. I'm just wondering though, what's to stop you getting one from a more recent van of similar weight, and plumbing that in? Obviously it won't necessarily be a bolt in replacement, but it might be quicker than getting one reconditioned. It might be something I'll have to investigate soon, as mine is a little stiff although the mechanical side is fine.

If my knowledge and recollection are correct the cylinder is the same across the LT range.
It is just the spring that was changed/different - depending on the rated/plated weight of the vehicle.

Unfortunately its a vw only part. Nobody else made them.

I had thought about fitting a later model version. But as stevest said its the setting up of the spring. Had a read through the manual and you need specalist tools to set the correct pressure. Once you have the right spring you adjust it by the sliding bracket. In other words a complete nightmare!

The idea is if i cant get new get one from a breakers and have it re conditioned. Cant be that hard to find somebody. As far as im aware its just a few seals, polish and re spray? Somebody must do all the old classic stuff?

I'll give zee germans a try. Had thought about just taking it out. My vans a motorhome and it must be near full weight. Is that a good idea and would it pass the mot like it?

I think it would actually be worse removing it on a motorhome, as it reduces the pressure when lightly loaded. So bypassing it would give you full braking effort all the time and make it more likely to lock the wheels up.

But seeing as the load you carry won't vary much, if you had a fixed braking restrictor (or a seized compensator LOL ) that should do the job assuming the restriction was such that it allowed a sufficient braking effort.

Just in case the extra numbers help you source a new one from outside UK

AHHH, OK, I thought the cylinder is all that was needed. I thought the booster was for all 4 wheels.

You can get rear brake cylinders from GSF. New front calipers are available and cheap enough.

I couldn't source a new back axle balance valve, so ended up buying a second hand one from an online scrappy.

That is not cheap! I've got a list of 4 companies who re-con calipers so going to give them a try. Plus im waiting on a reply from germany. Once I know more i'll post it.

Just to let you know that Eurocarparts can get them from Germany in 7/10 days.
