I was wondering if anyone might have experienced this, and maybe tell me some good news about fixing it. I have an 87 Cherokee with a 5-speed. I see no leaks, there is never any fluid under the jeep when parked, no wet spots visible on or in the Jeep. The clutch master cylinder goes empty all the time, though. Not too bad highway driving, but driving in town where the clutch is used more isn't pleasant. I have no idea what it could be. I am kind of hoping it is a line, and easy to fix (the brake lines all had to be replaced... especially after brakes went out on a steep hill because one of the lines broke) but my luck isn't that good. Someone had told me that a common problem with the 87's is the master cylinder, to look behind the fuse panel and see if it was wet. I didn't see anything, but haven't been driving it either. Have started it and pumped the clutch pedal. It is getting to be the season for off-road driving, so I really want to get it going again. I know the fluid has to be going somewhere...
