101 - Brake Proportioning Valve

[101RRS]

I have been rebuilding the brakes on my 101. I am at the stage of trying to bleed the system - front brakes bleed up OK but the rears were not working as no fluid was getting to the rear wheel cylinders.

Fluid was getting to the rear Load Brake Approprtioning valve but not past it. On checking it was seized in the no load position and not letting fluid through. On disassembling and cleaning it started to work - little fluid in the no load positon and full fluid flow on the loaded position - as it should be.

However, cleaning it out has now caused it too leak as there was some pitting in the actuation shaft - I now need a new valve.

It is Lr part number 599201.

Does anyone know where I might get one of these in Australia. I have checked the Four Wheel Drives catalogue but there does not seem to be an listing for these for any sort of Landies so may be unique to 101s.

Any help would be appreciated.

In the interim I will bypass the valve so that I can at least get the brakes working.

Thanks

There used to be a few places that would do stainless steel liners in brake components, could that be an option?

Thanks - there does not seem to be a rebuild kit for these - plus in this case it is the actuating shaft rather than the bore that is pitted - maybe a small speedie sleeve would work.

I don't know about the apportioning valve, but I had both the piston and cylinder re-sleeved on my 80" master cylinder. I took the whole assembly to my local "Brake Pro" agent who sent it away. I am sure your local brake service could do the same for you.

Thanks Diana - already had that done to the master cylinder - the parts manual does not list parts for this valve - nor is it "exploded" in the repair/service manual unlike the master cylinder, pressure switch or wheel cylinders. The service manual goes to great length to explain how to set it up but nothing on its repair.

It would seem not to be a serviceable unit even though it is constructed like a small master cylinder.

The brake people do not have any listings for kits even if I could get the piston sleeved. They also indicated that it appears to not be a serviceable unit.

Would love to be proved wrong though.

Gary, are you heading to Cooma?
If you are could you bring it along with you, I have a mate who is a VERY good specialist machinist, perhaps I could take some pictures of it and ask him for his thoughts?

I know nothing about the valve - but OMG I just looked it up on the P.A. Blanchard Site https://secure.pablanchard.co.uk/pro...roductID=33931 $489.00 before you ship it would be frightening.

Understanding that the valve is apportioned to the loading (a good thing for my S2B also) however what about removing it and using non apportioned valve from a Range Rover or similar? Otherwise is there similar device on trucks maybe you could hybridise one???

Do you know Allan Harding from the LRC of the ACT? He may be able to do a similar restoration for you!
