My hydroboost has been leaking for sometime and since its such a fine spray of high pressure fluid it has made a mess out of the drivers side fender area. The brakes work fine, the power steering does wine from time to time when the fluid starts getting low though. It seems a shame to replace the whole unit when the leak is just between the master and the hydroboost. Anyone ever reseal one of these? I found some kits here http://www.piratejack.net/Hydro-Boost-Rebuild-Kits.html Kit 50 is what the Cummins Ram's need.

That looks viable for kit... Just looking at the documents it look like it not to bad... http://www.piratejack.net/Download-docu ... tions.html

From the looks of it i am assuming the piston seal is what is leaking. It seems to leak when you press the pedal down.
