Someone school me on this since my knowledge level is zero. I picked up an older motorhome that has a hydroboost system- the power steering, brake booster, and windshield wipers are all connected and run off the same system. I'm looking to swap out my steering gear and so will need to refill and bleed the whole thing somehow. My first impulse was to use regular old power steering fluid, but I started doing some reading and I see a lot of people talking about "hydroboost fluid", and even found one guy saying that using regular PS fluid will cause a problem. When I google this, I just get back a bunch of results for PS fluid. What does the irate brain trust suggest?
