    You need to get a new master cylinder...the drum/drum mc has risidual pressure valves that are too much for the discs.. the metering block is not the only issue. I observed that the drum drum block has smaller passageways going to the back...it really isn't right formany reasons...get a new disc drum block and plumb it in or a wilwood with a proportioning screw knob to really get it tuned perfectly.

    Get some hoses for a 74 Maverick, with disc brakes. You may need to re posion the steel brake lines. There are some post about this from over the years.

    copy and past this into a google search bar...
    site:mmb.maverick.to proportioning valve

    click on the first result..
    from that I posted:
    I got the Granada discs installed and found a Fairlane 8" rear axle with 10" drums in new condition...my old rear drums were 9".
    I found;
    The drum/drum M/C has two 10lb. residual valves accesable just behind the flare fittings where you take the metal lines off.
    The disc/drum Raybestos MC36440 which is a manual disc drum master cylinder, for a '74 Maverick has a 10lb. residual valve for the back DRUM brakes in the front res. (which is for the back) and there is NO residual valve for the front discs (back end of the M/C). The residual valve for the discsa would be 2lbs, and are routinely sold, but only on cars where the master cylinder in at or lower than the disc calipers. So I am not going to ad a residual valve for the front discs.
    I am going to replace my drum/drum metering block(?) with either a new ford style combination distribution/proportioning/metering valve http://cgi.ebay.com/ebaymotors/1960-...item2eb5ce9554 or a combination adjustable proportioning/distribution valve; http://cgi.ebay.com/ebaymotors/ws/eB...=STRK:MEWAX:IT
    I would love to know if they do the same thing or if the ford valve does something extra to make my road car safer.
    I found this post here that stopped me in my tracks from buying the adjustable one;

    "The Granada came with a combination valve...not a proportioning valve. The combination valve is a fluid distribution valve, proportioning valve, metering valve and pressure differential sensing valve. The combination valve works better than an adjustable proportioning valve in wet weather."




    this trick of
    site:mmb.maverick.to
    followed by whatever topic you want to find is better than this sites search function.
