Power steering fluid on the VX calls for Dexron III but I could see someone grabbing a silicone based fluid for the steering and then putting it in the brake reservoir - bummer.
I too recommend doing it yourself - and get this great product called SpeedBleeders that makes it MUCH easier - order four bleeders (sometimes sold in sets of 2 but did not see on their site although the p/n that follows is off a 2pc package) p/n SB7100 @

I flushed Lisa's brakes this Sunday in about 15 minutes and used a quart of Castrol SynPower Dot 3/4. Be surer to capture and properly dispose do the flushed fluid.
