Well I used inpa to run the bleed sequence for each caliper (used the one way valve drain tube on the bleeder screw), topping off after each sequence.
Still not a big deal I needed to flush the system anyway.
I didn't want to put long term pressure on the seat leather or moving mechanisms, figured 'meh, what are a few drips?' Well the entire system drained. I miss understood the point of keeping the brake pedal pressed as keeping it from dripping. So I recently did a bunch of work to my suspension, and while I was at it I did stainless steel lines, and painted my calipers.
