    Ok thanks

    Ill strip the valve off tonight and see what I come up with.
    The local guy seems to have no interest so I will have to id the threads and get from ebay. Also we have a UK supplier here called Tube Gear but they need the thread also.

    ebay will have any adapters or fittings you need if you cant get them locally. whether the chevy stuff is metric or imperial will depend on how old the doner car was. if you take the proportioning valve to your local guy he should be able to physically try his fittings in the threads and order what he doesn't stock.

    The local brake guy has metric only
    My pipe with a vernier is 11mm ouside roughly and the front for the T piece looks 8mm
    Is it imperial or unf thread on the chevy brake parts?

    Ok will do
  • 24-03-2015, 14:19
    use a 't' for the front so the valve is totally removed.
  • 24-03-2015, 13:20
    Will I join the front pipes also with a tee or are they ok?
    I will stay away from solid objects while testing also..

    just join the pipes to bypass it mate. if you have issues with rear wheels locking then add a proportioning valve then. no point spending the money if it doesn't need it. make sure you don't test it in heavy traffic though for obvious reasons

    Join the pipes and bypass it or a fit a manual proportioning valve?

    Do away with it now you have disc /disc.

    I think that's what has happened but have tried a few of the methods I have found on the net and still no fluid to the rear.
