Welp, got the test strips today and according to them some copper
is present but it's still way good. The camera picks up the color difference a little better but to the eye it was the exact same color as the 30ppm marking. Considering this and also how it's still much clearer than my previous bleeds, and the fluid is less than a year old, I wonder if my suspicions are right about old fluid still being trapped in the loop somewhere and is causing the rest to dirty up? I would still suspect the ABS box but I'm not sure if fluid passes through it continuously or if it bypasses it somehow and only mixes once the pump is tripped by the wheel speed sensors
I wish there was a way to bench test the pump, cause I can never get the damn thing to go off when I want to - only when I don't and I'm least expecting it
