newby, clutch question

[Eric Henning]

greetings all,

Just subscribed as I most likely will be picking up an
86 4000 Quattro tomorrow. 

Quick background on me - longtime shade tree mechanic,
worked in a garage for a couple years during college. 
List of past interesting cars include, 60's mustangs,
Ford Capri (opel), Jaguar XJ6, air cooled VW's, Fiat
Spider, Audi Fox (remember that one?), 67 Impala, 69
Cougar, motorcycles, etc... Presently have Range
rover, Porsche 928, 76 VW Bug conv, 73 GMC classic
motorhome, not to mention some boring newer Toyota's.

Buddy of mine will sell me his 86 4000 Q cheap.  I've
searched the archives for the low clutch issue. 
Problem is the clutch appears to work fine however
clutch pedal is down by the floor and only uses about
two inches.  Shifts fine (except 3rd crunches if
you're not careful in the clutch footwork).  Would
just like some confirmation that most likely the
master or slave cylinder need replacement.  Don't know
if there is any leakage, sorry.  Master r&r seems like
a major PITA.  Also is there a way to visual inspect
how much disc material is left?

Thanks
