Hey guys,

My car has a steadily-increasing leak from the power-steering/hydroboost system that has gotten to the point of becoming a real issue. I have my car laid up to do some much needed work and figured I'd try and tackle this while I'm at it. I have no idea where the leak is coming from, and was hoping you guys could help out. All i know at this point is the reservoir level drops pretty steadily, and all that fluid has to be going SOMEWHERE. My plan is to get the area all degreased and cleaned up, start the car, and try and carefully watch to see where any drips/runs are originating. I know from experience however that this can be a very tedious process, so was hoping you guys who have messed with this before can direct me to any problem areas (particular hoses/flanges/seals that are known problem areas or common points of failure, the old "well 90% of the time if you have a pwr steering leak in a hydroboost car its coming from ___________" type of stuff).

Oh and just to be clear if I wasn't already, I'm talking about the hydroboost hydraulic power brake setup used stock in the 84 and some 85 (like mine) GNs, not the powermaster or aftermarket hydroboost retrofit setup (in case that is substantially different from the stock setup). thanks for any help guys!
 
I think your on the right track. Probably a leaky hose or the pump. Doesn't sound like an actual hydroboost problem.
