My guess is a leaking slave cylinder, back by the transmission. This happened to me 8 months ago. No leaking on the ground. But leakage collecting in the rubber boot on the slave cylinder. The mechanic showed me; peeled back the boot, and full of fluid. Symptoms were pedal to the floor, barely able to change gears. Replaced the slave cylinder (which should always be done at the same time as replacing a master cylinder because the slave will now be the "weak link") and all was well again. For about $270 parts and labor, including diagnosis, while on a cross-country road trip. BTW, bleeding out the air and topping off fluid was the first attempt at a fix; lasted a few days, but the problem came back. Needed the new slave.

To: vanagon@GERRY.VANAGON.COM Date: Monday, May 25, 2009, 2:44 PM Help! Last week I bled my clutch system as I had a very low pedal. I'm positive I did it when I replaced my clutch master cylinder a few months ago, but I didn't know wnat else to do. Well, I saw air and dark fluid come out so I figured I didn't get it bled very well when I changed the master. My pedal was much higher after bleeding. In the course of a week, my pedal has gone back down to the floor. Somehow, air is being introduced into the system. I just inspected the clutch hydraulic line and I find no leaks. Wouldn't I see leaks if there was an area that was letting air in? Anyone have any ideas? Thanks, Leo |
