Tried many searches, asked a couple people... getting ready refill my brake system. The larger section of the two in the brake fluid reservoir is currently connected to the rear brakes. I hooked my hoses up like the pic below (items 11 & 12) when I put on my new master cylinder. Is the reservoir larger because the volume of the rear brake system holds more fluid? Or am I backwards? Or does it not matter?
BTW - I know they are connected this way because I just sent my rear calipers out to Eric Shea for refurb and rear lines were left disconnected = brake fluid on the floor when I forgot to cover the reservoir with plastic to prevent the fluid from leaking out (no mysterious leaks / problems on the front brakes). |

I think the big reservoir feeds the front brakes. And further, this is because since the front brakes have bigger pistons, and do most of the braking and thus wear more, they have a bigger reservoir requirement.
The picture shows the big reservoir feeding the front chamber of the MC. The front chamber of the tandem MC feeds the front brakes. (That's not shown on this picture, tho) But it's that way so that if the back brakes fail, you're still left with fronts. The rear piston compresses the front. BTW - if your reservoir drained with the pedal depressed, I'd be concerned about the integrity of that system's piston seals... |

The large chamber is on the "back" of the reservoir, connects to hose 12, which is connected to the back chamber of the MC? |
