Anytime you contaminate a hydraulic system, the results are never good... However my opinion is, I would have used a Turkey baster to suck the fluid out of the resivior, instead of trying to bleed it, all you did was, contaminate the whole sytem, istead of keeping it contained in the reservoir... Live and learn... I probably would continue to drive it, or suck the ressivoir dry, and refill t with the proper fluid... The brakes would have been another story. I would leave that to the oil change people to check
