Hydraulic Pump replacement

If you can get a "rebuilt" pump from a FLAPS that guarantees stuff "for
life" or whatever, I could see going that way.  Otherwise, it's a crap
shoot like buying "rebuilt" brake calipers.  Sometimes they're done
correctly, sometimes not.  One that's been done by ZF (OEM supplier of the
pumps) probably would be the best bet.  Of course, you can reseal these
pumps fairly easily if you have access to a press to get the shaft out for
replacing that seal.  The rest of the seals (all available as a kit for
about $25) are O-rings.  Pump replacement itself is a bit of a pain but no
more difficult than, say, rebuilding a brake caliper.  I don't think there
are any bearings, just bushings.
