UNL1MTD Posted July 12, 2007 Share Posted July 12, 2007 I'm 99% sure my Master Cylinder is leaking. I just noticed 2 drops of oil right near the fuse box today on the commute to work. I was confused at first until I searched and it looks like this is the only thing that leaks in this area and it is fairly common. How long do I have before this leaves me stranded? If I shield/bag the fuse block (way stupid design btw to have the fuse block right in the flow of leaky MC fluid) what will happen? Will I just start loosing the clutch slowly or will it just abruptly quit and leave me stranded? I see some people get the auto store verisons for 30-70 bucks and they last for about 15k - 6 months. Others get dealership parts, how much do they run in price? This truck idealy will only get 7-8k a year put on it and my commute to work is going down to less than a mile in one month, so realistically it will only get 5k put on it.

pingpong Posted July 12, 2007 Share Posted July 12, 2007 The reman ones don't last as long as the new pieces. I agree the design is crappy. I had a XJ that had a leaky MC, and it eventually caused a fuse box fire :eek: Link to comment Share on other sites More sharing options...
XJ Maki Posted July 12, 2007 Share Posted July 12, 2007 You can just keep filling it up and drive it for a long time like that, keep a quart of brake fluid handy...eventually your electrical system will start acting wonky and obviously there's a risk of fire. The longer you let it leak the less likely you are to save your stock fuse block and replacing that is a wire by wire PITA. The clutch master isn't hard to swap out, there's one stupid nut that pretty much requires 2 people to get but otherwise it's a one person job in under an hour. Also when it comes to bleeding the system you can save some time & aggravation with a vacuum bleeder kit (about $30) Link to comment Share on other sites More sharing options...
HOrnbrod Posted July 12, 2007 Share Posted July 12, 2007 Now's the perfect time to do the 95/96 Cherokee booster/master upgrade. :cheers: Link to comment Share on other sites More sharing options...

UNL1MTD Posted July 13, 2007 Author Share Posted July 13, 2007 after checking the fluid level of the MC I guess its pretty clear that it hasn't been leaking/seeping for that long. The fluid level is at max, so I'm just going to keep an eye on it and clean up after it until a couple more pay checks role in and I can replace it.

UNL1MTD Posted July 13, 2007 Author Share Posted July 13, 2007 wow. dealer wants 225 dollars for it. napa wants 85. rock auto has them between 30 and 90. Thats a huge range. I am probably going to opt for the napa one. If it starts leaking again after 15k, I can replace it still for less and get another 15k. And if I honestly put 30k on this truck lifetime I will be surprised. Link to comment Share on other sites More sharing options...
Wildman Posted July 13, 2007 Share Posted July 13, 2007 Keep an eye on e-bay for the clutch master, I picked a new one up last year for I don't think over $30 w/shipping just for a stock/spair. Link to comment Share on other sites More sharing options...
carnuck Posted July 18, 2007 Share Posted July 18, 2007 Make sure you ONLY use Castrol GTLMA fluid and it'll last the longest! The other kinds eat the real rubber seals. Link to comment Share on other sites More sharing options...
87manche Posted July 18, 2007 Share Posted July 18, 2007 I've got the advance auto trubore one or whatever. I needed one and they were the only ones in town with something in stock, it's lasted about 20K miles and shows no signs of being crappy. Link to comment Share on other sites More sharing options...
mjeff87 Posted July 19, 2007 Share Posted July 19, 2007 put the same one in mine, and it lasted all of about 5K miles until it started seeping out the back. Considering how little I drive it nowadays, I just keep an eye on the fluid level and keep wiping off the pushrod :oops: I'll swap a good one into it one of these days......

UNL1MTD Posted July 19, 2007 Author Share Posted July 19, 2007 Considering how little I drive it nowadays, I just keep an eye on the fluid level and keep wiping off the pushrod :oops: thats exactly what I'm doing now with mine. Seems to not leak at all for normal driving with non stop-n-go, but if the clutch is ever in for anything more than a shift it leaks out. Link to comment Share on other sites More sharing options...
