In my gasser van the other day, I had to take it out for a quick ride to pickup two escaped dogs out the front door. Basset hounds can't find their way home once they leave for some reason, but I digress.... So, in a hurry, I start up the van, head to the end of the driveway and have to put all my weight into the brake pedal to stop, and heavy-ho to turn the wheel. After a bit, the brakes came back up and the steering did to, but it did intermittently mess up still. Fluid level find in the power steering reservoir.... so now looking for which area to start looking in. The pump made a sound (not the bypass sound) every once in a while too.
