| So here is a unique one that my local mechanics cannot answer. During my brake rebuild I replaced all my rear cylinders, rebuilt all my front cylinders, flushed with 2 gallons of alcohol. Replaced all the hoses, blew out with air.... used my pressure pot to bleed my system (and that has been a ROYAL PITA trying to get the air out).
Anyway, so went under for my 16th bleed and the fluid that came out of one of my rear cylinders was yellow / clear and not blue. OK. Freak out time. I continue to bleed and in comes the blue...
So I take this stuff that is "discolored" and start running poor mans tests on it. There is no separation, so it is yellow all the way through. So I sample it out into 4 different test samples, and I add Alcohol, DOT3, Water, and fresh DOT5. So after a few minutes the Alchohol, DOT3 and Water have separated and the DOT5 mix has not. Actually it is just lighter shade of blue, but mixed fine.
So I am stumped. What is reacting with my brake fluid that would extract the dye out of it. I am going to put some alcohol in with the DOT 5 and see if it pulls the color out after 24 hours. Oh, and this is ONLY happening in this one cylinder, and the amount of fluid I am getting feels about 2 cylinders worth before it goes blue. To add to the complexity, the wheel cylinders are probably from different manufactures (the left and the right) as Napa and O'Rielly only had 2 each in stock.

Odd issue with DOT-5, any experts?
