    I just converted to hydroboost, but the master cylinder is no good. I was thinking now might be the time for that 1-ton m/c. But will it bolt up in place of the m/c off an '87 2wd 3/4 ton diesel? Is it even a necessary upgrade?
    I'm also running a 14b with rear disks.

    i believe the one ton and 3/4 ton hydroboost cylinders are interchangeable, if not the same, call a napa store and ask,they will probably know if it will bolt up..

    Okay... went with the 1-ton master cylinder. Bolted right up to my hydrobooster I swiped from a '87 2wd 3/4 ton diesel. Man, I don't even have my rear disks dialed in yet (Wilwood prop. valve to come) and I can make this thing stand on its nose!!! /forums/images/graemlins/thumb.gif

    i put a 3/4 ton boster and m/c onto a 1 ton dually that was originally hydroboost, and the liens worked, so hmm..

    i didnt see any difference in appearance between the 3/4 ton and 1 ton m/c's though


    i would worry more about condition of lines and hoses and brakes and such, and of the fluid too, rather than worry about how big of a m/c is on the truck, bigger drums and discs would make it stop way better than anything else
