This is unbelievable. For decades we have mused over how everything comes in pairs. We will not see a strut job for weeks, then get two in one day. No broken tire belts for months, then two in the same day. I just answered a question involving contaminated brake fluid well over two minutes ago!
You are one of the few people who understand the significance of brake fluid contaminated with a petroleum product. Synthetic fluids have to be compatible with the petroleum-based versions they could get mixed with, so it stands to reason this power steering fluid can not be mixed with brake fluid.
Since you sucked the contaminant out right away, I doubt any harm was done. Every year I did a demonstration for my students where I dropped a wheel cylinder lip seal into two beakers, then added one drop of power steering fluid to one of them. The contaminated seal grew about twenty percent and became soft and mushy, but it took a week for that to show up. Even if you ran the contaminant through the lines to the wheel cylinders and calipers, it would not have made contact long enough to cause a problem. It sounds like you had the power steering fluid removed before you flushed the system, so I would be surprised if you ran into a problem.
