Don/DV,

The master I have appears to be exactly 1" bore. This seems appropriate for my setup. Baer recommended 15/16 bore. The question I have is, does the piston when depressed move the same amount of fluid to the front and rear brakes? I thought maybe the size of the reservoir might have some indication of how much fluid might be transfered comparitivly between front and rear. Also, after doing some additional research it appears that you can use just about any dual master cylinder provded the bore is correct for the application for a Disc/Disc setup as long as it doesn't have a "Residual Valve" built into the Master Cylinder for the rear brake connection. The residual valve will prevent the disk brake from releasing because it's designed for a Drum brake. Does anyone know how I can tell if the master has a residual valve by looking at it?
