  • single hole to dual MC upgrade.

    I posted this last night under 62beaters "split brakes" but have been advised to start a new thread as the cars are so different. I also read the 7/6 post but before I tear into it I thought I should gather as much info as possible (in other words, pick your brains some more


    My '64 Cruiser power brakes with the single cylinder of death are
    really starting to scare me. I did a complete rebuild oh, 5 years ago now; new rebuilt booster, new rebuilt MC, new lines, new WC's, rebuilt calipers etc. Now that single MC always made me a little jumpy so I'v been worrying over maybe swapping to a split MC, only I have never been able to find the TQ on the swap, if its up to me I will loose the power booster, go back to manual split disk/drum set up like on my mopars. Works, firm pedal, one less thing to sweat. what brought this on was bake fluid pouring out between the booster and MC so it looks like I am in for the repair anyway.

    Keep up the good work. the tech talk has been a god send for me & my Cruiser cruiser. RR

    I have a '62 Hawk that had power drum brakes and a single reservoir M/C. When I installed a Turner disc brake kit on the front. I also changed to a dual M/C. This meant I lost the power booster. The new disc/drum brakes were terrible and I was very disappointed. The problem turned out to be the brake pedal. The original brake pedal was for power brakes and had a different fulcrum, shape and metering rod for the M/C than a standard brake pedal. When I found and installed a standard brake pedal and metering rod I had excellent standard brakes without the booster.

      RR, Did you ever resolve the single cylinder of death issue on your 64 Cruiser? Here's why, I have the EXACT same problem...drum all around, leaking between the MC & PA units. Were you able to find a Dual cylinder that would bolt on??

        Lana Cruiser - Be advised that you do NOT "...have the EXACT same problem..." Cruiser64 has a disc/drum set up whereas you state that you have an all drum set up. If you are referring to your '64 Cruiser, it came from the factory with a dual master cylinder while the '64 Cruiser with disc/drums came from the factory with a single master cylinder.

            I installed a dual MC on my 63 Lark R2 that came equiped with factory power disc brakes. Here is a list of all of the parts I used, all were from NAPA. 36307 MC, (2) 813-1204 lines, 131x3 fitting, 3220x4x2 fitting, 7909 fitting, 7910 fitting and 7933 fitting. The total cost for the all NAPA parts was under $90. I used the original brake light pressure switch and I had to adjust the original MC push rod to minimum.
