    Looking through that ignore everything I've said. They changed the system, but I'll still look at the master cylinder first.

    the problem is definitly in the distribution valve! the master cylinder was a problem and since I replaced it there is fluid flowing to the valve just not out the back of it.

    so I fixed the distribution cylinder today and it was a really easy job. just pull it out, pull it apart, clean and re assemble and re install.

    The most difficult job was getting the solid lines back into the damn cylinder!

    Also the nut is on F-ing tight!

    Glad to hear that what did you find? I never ended up getting the valve off sheer luck so I never got to open one up

    There is an internal plunger type thing with a spring bearing that only allows brake fluid to get to the rear when the bearing is compressed, when the rear runs totally dry there is no pressure and the plunder moves so the spring bearing isn't compressed.

    Once you pull of the large nut on the end the plunger can be undone with a flat head screwdriver (just don't loose the small rectangular steel bit that compressors the spring bearing.) and I just done a good clean out with brake cleaner and replaced everything and hay presto-its all fixed!

    To replace the unit was $250 recoed or $400 new so I guess alot of people have paid more then they deserve!
