Torq_Shep Posted November 16, 2020 Share Posted November 16, 2020 Has anyone found a replacement clutch master that doesn't start leaking after ~2 years. I remember on my cherokee I could never get one that wouldn't leak. I also plan to fabricate a little plastic box below the clutch master to catch anything and keep it off my floorboards if it does start leaking but while I am redoing the interior I want to replace this master. From my research it looks like they are the same from 1991-1996 even though the slave changed to external in 1994. Is that correct? Link to comment Share on other sites More sharing options...
1987Comanche Posted November 17, 2020 Share Posted November 17, 2020 Yes, the clutch master is the same for internal and external slave. I found a plastic clutch master that's lasted pretty well. The aluminum ones lasted about 3 months each. I think it was either Bendix or Lucas. Link to comment Share on other sites More sharing options...
Torq_Shep Posted November 17, 2020 Author Share Posted November 17, 2020 I went ahead and purchased a plastic Bendix one to see if that works out. It will be several months before I get around to actually driving this thing but still just wanted to get it replaced now. Link to comment Share on other sites More sharing options...
Big Dan Posted November 17, 2020 Share Posted November 17, 2020 I bit the bullet and paid the $200 for a Mopar, pre filled, clutch master and slave assembly. It hasn't failed me yet and it's been on about 3 years. Sent from my Pixel 4 XL using Tapatalk Link to comment Share on other sites More sharing options...
SVPete Posted November 17, 2020 Share Posted November 17, 2020 Not sure what the problem is. I've replace mine twice over the years. Figure I'm getting about 10 years out of them. Bought from AutoZone both times. Once in Kansas in the late 90's, once here in AZ. Now that I've jinxed myself..... Link to comment Share on other sites More sharing options...

However, I am going to fab something up to protect my floorboards and new carpet from damage if it does leak. Link to comment Share on other sites More sharing options...

I will have to flush the slave with isopropyl but that should be easy enough. Will definitely be doing that for the clutch as I cannot be always worrying about the clutch master leaking again (they always do). Link to comment Share on other sites More sharing options...
jamcomanche Posted March 3, 2022 Share Posted March 3, 2022 @eaglescout526 sorry for the ping. When you have a minute would you be able to get me a part number for a genuine clutch master cylinder and tell me the best place to buy it? I put a new sachs unit on back in september that started leaking on me already. Link to comment Share on other sites More sharing options...

cruiser54 Posted March 5, 2022 Share Posted March 5, 2022 You know, there was an issue with the flexible clutch line between the master and slave cylinders. The rubber line reacted badly to the fluid they used and shed off some gritty stuff. That stuff trashed the cylinders. It was always recommended that the line be replaced when a cylinder failed.

There’s some 84-86 oddities that carried over until probably late, late 86 like the mounting of the clutch master. Two styles, one has the bolts top and bottom and the 84-86 has the bolts mounted on either side of the master. Here’s the PN I see for 87-90 53004467. None exist new.

watchamakalit Posted May 13, 2022 Share Posted May 13, 2022 So whats the decision on the best? Mopar? Or should a guy just bite the bullet and auto swap? Mine is leaking again after 2yrs. Link to comment Share on other sites More sharing options...
cruiser54 Posted May 13, 2022 Share Posted May 13, 2022 Did you replace the hose at the same time? Flush the system? Link to comment Share on other sites More sharing options...
watchamakalit Posted May 13, 2022 Share Posted May 13, 2022 I didnt replace but flushed it all really well I had read about the fluid issue. Maybe id just be better off with a complete new system. Link to comment Share on other sites More sharing options...
cruiser54 Posted May 13, 2022 Share Posted May 13, 2022 At least the hose for sure when doing the master. Link to comment Share on other sites More sharing options...
watchamakalit Posted May 18, 2022 Share Posted May 18, 2022 Ive been thinking about it, I did change the line because I went to an external slave ax15 when it did the 4x4 swap. The while system was new. Apparently something isnt happy by the looks of the juice. I think I might just swap the whole system again and try to stay up on flushing it periodically.
