Single to dual reservoir conversion

jazak5 is correct, the rear goes to the front brakes, the front goes to the rear .

Not all master cylinders are set up that way.

And that would have been useful information. When you say you did a brake conversion, it’s normally a safe assumption that you installed disks. In which case the larger reservoir goes to the front brakes regardless.
