Need you thoughts on Clutch Master Cylinder replacement

hey guys,
Thinking about replacing my clutch master cylinder since it has no cap. I've tried looking around and picked up caps off cylinders from other YJ's but they don't fit. This leads me to believe that the previous owner had the cylinder replaced with an aftermarket one.

Now my question is, I've heard that it's best to replace both the master and slave since replacing one puts stress on the other, is this true?

Basically, I don't want to drop my tranny to replace the slave.

What should I do?

In the time I've had My jeep, I'm on My second replacement. The first one was a cheapy plastic housing. Somehow, the return spring inside the unit broke into 4 pieces. but I spent 80 dollars on a nice aluminum one, had no problems since. I haven't had to replace the slave, but I should probably look into it.

If You get a new master, You shouldn't have any problems if You leave the slave alone really.

stay away from the parts store brands. nothing but trouble when it comes to these things. if it fits your 90, you're welcome to my old one. bout a year and a half old and a dealer part. i went through 3 of the parts store versions before getting fed up and dropping the big bucks on the mopar master. never had a problem with it after that. only reason i'm getting rid of it is because i've since switched to an external slave setup since i've had that go on me 3 times since buying the jeep in 02. PM me if you're interested.

I have never replaced my slave but had to replace the master several years ago. Unless you want to do the job over in a year or so do not buy the part from auto zone etc. My Auto Zone master lasted about a year then went bad. It was very cheaply made. I then put on a new original equipment master and have not had any problems.

Heh, I guess I got lucky with mine, I've had it for over a year now with no trouble.
