there is a master cyl for both, brakes and clutch. the clutch being the smaller of the two on the fire wall and of course directly in line with clutch pedal, it depends though, you might have a slave cyl problem on the side of tranny, depends if your getting fluid through master and to slave to determine which is bad, it is an easy fix for do it your selfers either way, the only issue is bleeding air out of it(i'm sure you can find all info in a search) but i believe your looking at aprox. 100.00(parts) or so for either and if paying someone to do it, look for aprox 1 hr labor of anywhere from 50.00 to 100.00 per hr, parts are widely available at parts stores which might save you in mark up if buying from a mech.
