Clutch MC is on the firewall in front of the driver, the brake MC is under the left fender. You either have:
- A leak in the line to the slave cylinder from the MC, could be at a fitting, junction, etc. Look for a wet spot
2. A bad MC or slave cylinder.
Is the fluid level on the MC down? Try bleeding the system and see if the clutch action improves. I assume (Yeah, I know, big mistake) that you do not have a hydraulic throw-out bearing that is internal to the bellhousing...they tend to be whole 'nuther kettle of fish.
