The brake master cylinder on my '91 C2 is "sticking", i.e. it feels like I have to press past a resistance point before I can apply brakes. I think I read somewhere that this could be due to new brake fluid and old seals not always mixing well.
Would like your opinion - should I replace the master with a new one ($,1,500) or a used one from one of the reliable sources? Is there are a rebuild kit out there somewhere I may have overlooked?
Thank you.

That's it, exactly. Light braking only. It feels like you have to get past some initial resistance and then everything is fine. Makes smooth braking in city traffic a little harder because I have to hit the brake harder than I should and then have to ease off - hope my convoluted description makes sense.
I started after a brake fluid flush replacing very old fluid from a previous owner.
Glad I am not the only one with this but would really like to avoid spending crazy money for a new m/c.
Looks like rebuild is a viable option

I don't think I'd buy used for that component. Rock Auto (no affiliation) has a series of options from 'send yours in for reconditioning' ($50-$80, depending on model) to $500-$650 for new.

I have heard rumors that they are rebuildable, however, not according to Porsche and I don't know a of a "Kit" to do it. People just seem to try and match up some new seals for their exsiting master.
It does seem like rediculous money for a master.

WRT the Rock Auto rebuild operation, these are done by Cardone which is a big rebuilder of halfshafts. Presumably, they know what they're doing and at the price you're not risking much; what's $50 if you're looking at $1500 for a new master from the dealer?
