    I'm gonna install 3/4 ton diffs in my '78.Do I need the brake booster and cylinder from the 3/4 ton truck?It's all on the donor truck,so should I just install the whole brake system?

    Yes and no.......The brake booster for a 3/4T with the 13" brake option has more assist. Will your 1/2T booster work, Yes. You may have a little more peddle effort with the half ton but it will work fine. If you have the 3/4T booster I would use it as it is an easy swap and gives you a little more boost if you ever need it.

    If you really want to make a differance, put a 1 ton master cylinder on it. Thats what i did and i couldnt believe the braking ability.

    Does the 1 ton master cylinder mate up to the 1/2 ton booster?

    I have 1 ton axles and I am still running the 1/2 ton master cylinder and booster. Everything works fine but I plan to upgrade it someday.

    Are you still using vacuum assist or did you go to hydra boost?? If you are using vacuum what application is the booster intended for.

    Ditto with Wayne on this - running the same stock 1/2 ton stuff on my 79 with no problems, and no pedal effort change over the 1/2 ton axles versus the D50/14BFF.
