I mentioned the residual pressure valve to keep pedal play/throw to a minimum.

My daily Dart has a DrDiff MC (1-1/32") with large C-body calipers upfront and drums at the rear, but since I haven't installed a res.pressure valve yet, and therefore have some more pedal-movement in the system than I would like.
Besides that I also think I would like to try out a slightly smaller diameter MC as I think my brakesystem would benefit from a little more hydraulic pressure.
