Any advice, do I crack this thing or do I give it to local Z doctor. Starting to get smaller parts done(heater core, front turn signals, etc) and I need to get this one done. Read the manual and that section about put me to sleep. Any experiences are appreciated

Order rebuilt one from MSA, or other source. Done.

I think those things are starting to get expensive. Wondered what one would cost vs to rebuild, even having the local shop rebuild it.

Nissan OEM brand new...that's what MSA sells too--I got one from them--think of it this way--you probably won't have to replace it for a long time and it's a very important piece of equipment...looks good all new under hood with the shiny fill caps too.

I have seen some on ebay lately for around maybe 40-60 dollars. I forget if they were re-built or brand new. Has anyone else seen these? I'm not sure if they're any good.

If you're going to order one, get a rebuilt one from MSA (or other source) like Montoya fan suggests. The "rebuild kits" I've seen are only a few dollars cheaper than a fully rebuilt one, so it's not worth the effort. New ones are crazy-expensive.

What's wrong with yours? Does it not hold vacuum? Poor pedal engagement? My brakes didn't grip till they were almost all the way to the floor, a problem I traced back to a malpositioned reaction disk, easily fixable (thanks to advice from folks here). Saved myself some cash--maybe yours is similarly afflicted?
