The brakes work twice as good as they did before, so there is no need for the 1 ton master cylinder. It just makes it a pain, to have to switch brake lines around....
If you have a M/C that works great then, well, great. I would like to caution members about buying the rebuilt units. I bought a rebuilt unit and was driving down the road with working brakes most of the time but sometimes I'd go to stop and no brakes! I replaced that M/C two more times, (warrantied for life deal) same thing. At this point I'm thinking it has to be something else. Local mechanic asked if I was buying rebuilt units...yup! He said to buy a new unit and, walla, brakes worked fine. He said as the units get old the bore wears. When the units are rebuilt they are not re-bored and fitted with a larger piston, just the O-rings and seals are replaced. He said that it can cause the piston to hang-up in the bore and the fluid to pass around it giving you...no braking power. Bought a new unit for only $10 more than the rebuilt and no more problems. Just thought I'd let people know so they can avoid the problem I had. YMMV.
