C30 Manual Clutch Hydraulics Question
 

Doesn't seem to be a very active forum here, but I'll give this a try: anybody know where the hydraulic clutch on a C30's manual transmission gets its fluid? Is it pulling it from the brake master cylinder?

My pedal sometimes (possibly related to hot days, not sure), isn't coming all the way up again. Wondering if there's an air bubble in the line and bleeding might help -- but I can't even find where is the fluid reservoir.

TIA
