I just rebuilt my hydro boost with a seal kit because it was leaking power steering fluid. I carefully separated the halves of it and just replaced the one oil seal that sits around the piston, and then the figure 8 seal. My hydro boost was acting normally except for the P/S fluid leak up until this point.
My hydro boost is not leaking power steering fluid anymore, but now when I start the pickup or I'm moving slowly, it acts like the brakes are self applied without pushing on the brake pedal, because I can give it throttle pedal pressure and it takes more power to move the pickup now. I understand that this is most likely caused by a plugged/restricted return line from the hydro boost, but is there something that I did to cause it when rebuilding the unit?
Thanks,
Doug
