This may be a bit late, but Arek had a few compensators re-manufactured a while back. Worth a shout.

Hi Hugh

Past parts were unable to fix the compensation valve.

Do you still have yours for sale?

Thanks
Ollie

Just for info it is possible to determine the spring rate given the following;

Diameter of the wire used

Overall diameter of the spring

Number of active coils (coils that don't touch)

Constant for the spring material (Usually the same)

There is an online calculator thingy that will do it for you. (i'l try to find it and add a link later)

Hope this may help someone who has a regulator of unknown load

It is also possible to increase the rate of a spring by cutting coils out and making up the gap with a spacer if you're really desperate!

Hope this may be of use to someone.

Cheers

Thanks for your help

hi ollie. i didnt use him in the end, i sent mine off to a company called past parts who did an amazing job but were unable to get it to me before my trip so i bit the bullet and bought the unimog valve which is identical apart from the spring which is much heavier duty, we switched it with the existing one and its been fine.
the plus side to this is i have a fully recondidtioned valve up for grabs, it even had a new internal piston machined as the original one was knackered.
try them, if not this is available for £250.00 (unimog one was £390 i think)
hope this helps.
cheers hugh
If in doubt ,pin it !!

Hope you pick this up from such an old post.

But can I have the details of the chap in Germany that refurbishes the brake regulators?

Thanks

There is one valve, two levers and ten springs which cover all models from 1975 to 1997. Although they were colour-coded, I doubt you will be able to see what you have.

thanks for this, it all sounds very technical.ive been looking at a similar soloution using a regulator off a L200 pickup as it looks quite close to the lt althought the mounting points are on the opposite side but i can deal with that. i do wonder just how vital the spring rate is on these old vans giving that 90% of them probably havent worked for years.
be interested to know what regulator he used. 

If in doubt ,pin it !!

I've been spending!  I have worked on cars and bikes for just over 25 years but never made a brake pipe.  So I had to buy a flaring tool and pipe bender.  Managed to pick up a NOS pressure regulator for the bargain price of £35.  The part number is 1H0612151C.  It's fitted to a number of different VW's and Seat's.  I didn't know until after I bought this one that some are pressure sensitive and others are load sensitive.  Luckily I bought a load sensitive one.
 
My plan is to measure the position of the regulator arm from a fixed position on the chassis.  Then cut the pipes to release the pressure and measure the travel of the regulator arm from the same point.  I can then work out how far in the travel the regulator is.  For example if the measurement I get is 175mm when connected and the travel measurements are from 100mm to 200mm.  I will then know that the regulator is set at 75%.
 
I'll put the new regulator as near as possible to the original's position and also take measurements of the regulator arm at maximum and minimum.  Then connect it up and bleed it.  After that I will set the spring up so that the arm is in the same percentage of travel position as the original.  If the new regulator has more travel (which I suspect it does) I'll increase the percentage slightly so that it is fully open at approximately the same time as the original.
 
My main concern is the spring rate.  The regulator's are obviously designed to work with a certain size spring.  From looking on Vagcat the size of the spring on the car is a lot smaller than the one on LT's. 
 
I found a thread about lowered Golf's which have regulator's.  When the Golf's are lowered they have to adjust the regulator.  Otherwise the back braking force is too great and the back of the car can swing out under braking on corners etc.  They have altered the regulator by stretching the spring in a jack.  I could try this method if the spring rate is too great.  I don't fancy having to try and fit a smaller spring because the one on the van is quite an odd looking size.  I don't think finding replacement's will be easy.
 
What does everybody think?  Do you think my reasoning is sound or have I missed something blindingly obvious?

You will need to do what Volition82 has already done. His solution worked perfectly.

Thanks LTCamper89 :-)

(LT35 Brake Pressure Regulator Valve leaking)

Yes I have a habit of searching old forum posts rather than waiting for replies!

After a few more forum searches, have sent it to PastParts.co.uk for refurb in Bury St Edmunds UK, £80 +VAT, with 5-10 day turnaround. They've done a few of these for LTs in recent months. They refurb brake & clutch parts (particularly cylinders like this thing), they're also making me front flexi hoses as my mechanic had trouble sourcing those for MOT too.

Thanks for your help!

From what I can see you have fitted a pressure reducer, however for your safety I would ask Brickwerks about it. They deal with both t3 and LT whereas Just Kampers do not deal with LT.

Possibly another swear filterLOL

Not sure if the regulators are the same. But I replaced mine with one from just pampers. On my T3 £118 - been working as expected for over six months

Hi Steve, do you still have a contact for the "Guy in Holland" who is getting Bosch in Italy to manufacture Brake Pressure Regulators? Looked at hscale.com, not there. MOT failure... my one's leaking!

Excellent news, I've been afraid of it happening to my old bus for years and she failed her MOT today on it leaking! Looks like I'll be sending mine to Past Parts too!! Cool
Should I cut the Blue wire or the Red wire???
