The Stovebolt Site Forums The Parking Lot Big Bolts I give up on a master cylinder

The bennefit to having a new master is you'll be putting full pressure to the rest of the system.
The disadvantage to having a new master is you'll be putting full pressure to the rest of the system.

What I mean is that all of the rest of your componenets may be borderline now, and being able to push harder may just blow one out. This is where you come into the territory where a dual circut is safer than a single, something as simple as a torn cup in one of the wheels slaves will be all it takes. Wether you keep it stock or convert it, it's best to collect all your parts and do the whole system at once.
Dual circut is safere, no doubt, but there's also the fact that most of these beasts have been on the road for decades with a single circut, properly maintained they will be on the road for decades more.
