Replacing the Slave Cylinder - master too?

Hey dudes,

Im doing a clutch job and slave cylinder in my 92 YJ 4.0L, the paper included with the parts suggest I replace the master cylinder as well as the slave. I really dont want to spend the other 200 bucks for a master cylinder, but Im wondering just how important it is to do both. I dont mind if I end up needing a new master down the road, but I sure dont want to replace the slave again. Can a poor master cause the slave to fail sooner? Or is it just a matter of performace?

Thanks,
Duncan

Yes, you should.

Rusty is looking to open a parts store in Canada. I've never seen him so excited.


Master and slave together.

She's going to bury me in this thing.

Since you have an internal slave, it is best to replace the master at the same time. The logic being, that if the master goes out, it will send debris down the line and damage your slave. I think I paid $90 for a new (not reman) master. The master and slave tend to have the same life expectancy, so save yourself the heartache and do it now.

It's wise to change them both unless you want to risk pulling the trans again soon.
$200 is about right for a master and slave maybe a little more if you spring for higher quality parts.

Pat, in all due respect he said, "200.00 for a master". Not where I come from.


That's what universal health care get you Canoodlians...expensive parts

Here is a quote from his post.

So you can understand a little confusion on my part.
BTW New Mexico is not part of Canada

question is can I just do the master in a couple weeks/few thousand Km's? OR does it need to be done right now?

you're going to have the transmission pulled anyway- best to do both IMO. Two weeks down the road, you're not going to want to pull your transmission out AGAIN. Nothing would happen in that two weeks, but I've driven a YJ that had a new slave with the original master and it SUCKED. The clutch was like an off/on switch more than something that slides
