Clutch Master Cylinder

I think I need to replace my Clutch Master Cylinder. I noticed when I push the clutch in fluid is coming out where the rod from the pedal goes in. Does this sound like the fix? ANd is it hard to replace? ANy tips would be appreciated. By the way its a 82 cj 5 3 speed 6cyl.

Sounds like the diaphram is compromised....the clutch slave is easy to rebuild, take if off and tear it down, no directions are really required. If the bore is pitted you may need to polish it. If it's really pitted by a new/rebuild slave.

Master cylinder leaking. Replace it and you will fix the leaking problem. Might want to do it soon, as the brake fluid will rot the paint off the bulkhead.

I read the post clearly but still typed slave cylinder, JD is correct for sure. The leaking clutch master cylinder will rot the paint quick, just like the leaking brake master cylinder on my CJ.

THe new master is not that much more than the rebuild kit. Go for the new master cylinder. My was replace in about 15 mins. Easy to do.

Hi Phil, I tried to send a msg to your acct but your inbox is full.

I was reading this post about your leaking clutch master cylinder and was hoping you can help me out. I've got the same problem with my '80 CJ5: the clutch master cylinder leaked all of the fluid onto the floorboard underneath my pedals.

Did you just replace the clutch master cylinder or did you also replace any other seals, etc.? How difficult was the replacement? My cylinder's got about 1/2 the fluid left in it--how did you drain the rest out of it to do the replacement?

I also read that this problem caused a lot of damage to the fuse box and fuses, but that was reading some Cherokee posts so hopefully mine wasn't affected (it doesn't appear to be).

Any advice you can pass on would sure be appreciated. I'm hoping to get this fixed over the weekend.

Thanks very much!

Erik
