    To all :

    I bought one of these, and Ian did a good job.

    You may think you do not need one as yours may not be leaking. However they often seize up without leaking.

    They also sometimes weep slightly....for years.

    If yours has not been replaced for many years, the chances are that it has seized.

    Apart from operating it manually somehow (which I am not even sure is possible) the symptoms are that when you have to brake in an emergency, the rear wheels lock up. (someone please correct me if I am wrong here).

    And you really don't want that happening, particularly on a slightly wet road.

    That is a fair price. I paid more for a parts original about 35 years ago.

    I fully concur with Beano's above post.

    Are you going to do wagon valves as well?

    No plans at this stage for wagon valves as they are quite different.
    505 wagon valves should still be available new in Europe.

    Becoming hard to find even a good/fixable dead 'un for the 404 - the last one I found had been brazed up, so not much use for recycling.

    I have a fair number of dead repairable valves for 404,504 and 505 sedans but need to keep the stocks up so exchange works for me to have stock on hand ready to finish off as needed.

    I am complete underwhelmed by the response I have had to this service and can only assume that most of you guys have blind faith in your cars braking systems even though at least 30% of your cars are probably faulty by now.

    Gday Ian,
    My 404 is definitely one of the faulty ones. Every part of the brake hydraulics has been replaced when I got it except said valve. When I slam on brakes the rears lock up (incidentally how can the handbrake be such cr**p when the rears can lock like that!). Problem is Ive got too much else happening to tackle the job right now - might be a few months til I get round to it :-/
    Regards Rob

    Mine works ( reco'ed in Melbourne during resto in 2014-5)

    But fear not, once I've found a good dead-un it will be coming your way so I'll have a spare, as car intended to see me out.

    Ok, I'll confess to testing the 504 brakes on a downhill in the wet last weekend and yes I did manage to lock up a rear wheel. It was good to know the limit. I still have every faith in my 504 brakes. I just had new tyres installed yesterday (the others were 7 years old) so now it drives (and brakes) even better

    You will find it behaves far better with a new valve
