To the OP...
I offered in a PM back in mid July to go take a look at the car you were thinking about buying here in Nashville, but never heard back from you.
I told you in the PM how picky I was, so perhaps if you had gotten back with me about this car, you might have discovered the need for a $700 exterior and wheel detail as well as the clutch problems you are now having.
Live and learn...
No offense, but it would take some divining rods or chicken bones to predict an impending hydraulic problem on an otherwise clean car. If he had Barney do the PPI, he had pretty much the best in the business do the PPI. I'm forced to assume it wasn't gushing clutch fluid at the time, and I'm pretty sure the OP has eyeballs and would have been aware of the rim rash....
It just comes across a little 'hood to be putting a guilt trip on the OP for not taking you up on an offer.
As I said, I don't know you personally, and stuff doesn't come across on the internet well sometimes, so take it with a grain of salt. Sorry I'm not as diplomatic as bigbadberry
Back on topic:
The Hydraulic systems on these cars isn't a "common" source of problems save for the ABS system when it gets on towards 20 years (as some of the early car owners have discovered). My factory slave cylinder finally gave up at ~220,000 miles, so a 30k failure is odd. The good news: The parts are relatively cheap, and as others have pointed out, shouldn't involve much down-time. I'd speculate with so few miles in 10 years the internal seals might have dried out or not been as well lubricated as a more-consistently driven car. Rubber, as a material, does have a shelf life.
It sucks to have this happen right after you got it, but it's really not indicative (hopefully) of problems to come.
That said, you have to remember, even though it's a Honda, it's a higher-strung Honda, so will need a little extra attention vs. a new Accord. Hopefully you'll have it back and driving quickly so you can get back to enjoying it.
To date, I think bngl3rt is the only person who I've seen end up with a basket case that was supposedly a clean car through little-to-no fault of his own. (Mine was a basket case, but I knew good and well how much maintenance had been deferred going in...so that's a bit different and due to neglect).
