FYI, you can yank the power booster off of most any power brakes to simply use a non power M/C and brakes will work fine. Depending on model can even bolt up with hardly any change at all, sometimes a booster holding bracket has to be unbolted from the firewall to enable room for the M/C by itself. The brakes will work with far less effort than a power booster with engine off to make no vacuum as well. The booster when not enabled takes quite a bit of force to work.
