    That looks like the 81 style.... Not original to your 79.

    Somebody missed one of the holes on the bracket when it was replaced too.

    they missed all the holes, its just hanging by the pressure of the lines being so stiff. what should i do? replace with the correct one or try and fix what ive got as far as mounting?

    You should be able to remove the two nuts holding the master to the booster, hang the bracket where it belongs and re-install the nuts.

    If you have any question about the function of this one.... Get a new one from NAPA for $30, bench bleed it, swap it over and bleed your lines.

    Don't put a cast iron master cyl. back on it, if you have to take the lid off more than once it going to leak.Try to leave that one on their,I just put one of those on my 78.

    Say what!? maybe because you have a 33 year old seal or a China made chrome lid on the master, but lets face it GM and others have use them on millionS of cars for decadeS

    im gonna have to change it to one of those millions that GM used. before i took the motor out the brakes were really grabbie, liked to lock up on the left side. im putting all new pads and shoes on it so why not change it back to what its suppose to be so i'll know its right.
    GEEEEEZ I hope it dont leak after i take the lid off a couple of times :eek:

    it could be a flexible line issue, stopped up hardline, caliper, prop valve or even just a warped rotor.

    these are all areas to investigate...

    Save yourself the cost of extra brake fluid and replace the rubber lines while you have the system apart.

    You will have to rebleed the whole thing after you replace the master so you might as well replace the rubber lines and bleed it once.
    The stock rubber lines aren't very expensive. (Two front and one rear will be about $50)
    The Russell kit (all three hoses, stainless braided steel) is $70 at AutoZone.
