Could be a problem with either your slave or master cylinders. Check this thread for more info on how people's clutches have failed in various ways. http://www.jeeppatriot.com/forum/showthread.php?t=3208

 

Check your fluid.

 

brake fluid is low, i can not even see the bottom...where can i find reservor for clutch fluid..or clutch uses the brake fluid reservor...?...thanks..

 

Same MC, err make that reservoir, for both I think. Top off the fluid and hope there isn't a leak. Check the fluid often, if it drops, get the leak fixed ASAP. Also check where you park for any wet spots. If the fluid got too low, you may have to bleed the systems.

Although the reservoir serves both systems, according to the owners manual, leakage in one system should not affect the other. If both systems were acting up, perhaps the reservoir itself is leaking.

I topped off brake fluid. Brakes are ok. Still no pressure in clutch. How do I bleed the clutch system? Thanks.

 

I've never bled a clutch, just brakes. That's usually a 2 man job, but there are one man options. I'm guessing the basics are the same, but perhaps someone more knowledgeable can chime in with a step by step procedure.

 

the dealer is telling me that master cyliner need to be replaced. the part costs only 90$ but the lbor cost has one more ZERO!

We have a winner! :banana: :smiley_thumbs_up: :banana:

Sorry...couldn't help myself... :doh:

 

or just go to a private shop, dealers always cost more

 

I haven't had any problems with mine. I check the fluid every time I'm under the hood, hasn't changed since new.

 

This is a clutch master cylinder, not a brake master cylinder.
The dealer is still working on it after 8 hrs, they could not finish the job today, it will be tomorrow noon.

 

It's fixed. after 1.5 days at dealer. i think the dealer did a good job. lot of people here in forum were confused between brake master cylinder and clutch master cylinder. the problem was with the clutch master cylinder and its hydraulics sytem.

 

let me take my words back about good job.
the dealer repaired the clutch master cylinder yesterday after spending 1.5 days...but suddently i had new problem withn 24 hrs of the repair...i was driving in 5th gear and suddently the pat went in nutral...i thought gear slipped but i was wrong...the stick was still in 5th, but it was not engaged...i tried put in 3rd, but it didnt enganged...tried put in in nutral, and it engaged in 4th,,,tried put in 2nd, it did work,,, reverse gear works, 1st does not work...what the hell happended suddenly?
current: 08 Pat 4x4 5-speed 49,500 miles
previous: 97->08 saturn 4x4 5-speed drove 185,000 miles

 

All master cylinders usually have a repair kit comprising springs seals & washers for a few ££--$$ & about an hours fit time??

 

yes, it takes long time acoording to 3 different mechanics...as far as i was told by different shops, in Pat, you have to open up all the way to clutch gear assembly in tran to replace clutch master culinder and associated hydraulic line...Who knows? may be they just don't know how to do it?

 

There is actually a master cylinder RESEVOIR (canister that holds the fluid) that is shared by both the brake master cylinder and clutch master cylinders...Often times the dealer will refer to the clutch master cylinder as a clutch actuator. If they needed to remove the transmission, which I can only assume was the reason for removing the shift cables, they also changed the clutch SLAVE cylinder which is on the transmission input shaft.

 

I don't understand why people who know absolutely nothing come and post on here. Like seriously the laat poster stole the cake. There is no vehicle ever that shares a master cylinder with the brakes. Obviously this person has no idea what a master cylinder doesif he did he would realise that if it shared a master cylinder the brakes would be applied when you pushed the clutch and vise versa. Yes the patriot clutch and brakes share a fluid reservoir. However thats just where extra oil is stored. From the bottom of the reservoir there is a hose that goes to the clutch master cylinder. Its in a very tight spot right behind the strut and wedged in behind the brake master cylinder but trust me its there.

 

You're just an a$$hole aren't you

 

Clutch Master Cylinder and Clutch Slave Cylinder..........Leaking Slave Cylinder = No pressure in Clutch Pedal....

 

i think people are getting confused here with the terminology. I am no mechanic but do my own work- not clutches-but like brakes, tuneups etc. But, the way I understand it is this....

The brakes AND clutch share the same master cylinder. The clutch/transmission has a slave cylinder built inside the housing requiring the trans to be removed to get to it.

If it fails, it's not a "clutch" or a "clutch part" and should be covered under power train warranty. A "clutch part" are the parts sold to you when you buy a "clutch" which is pressure plate, clutch disc, TOB. At least that's how I understand things. An assembly inside the trans should be covered if it's not the clutch itself. With that said, I see you are well out of warranty unless you have lifetime in which case I'd fight them to cover it.

it's still a pricey job. that's what went out- slave cylinder inside the trans. There is no dedicated clutch master cylinder. I had one go out on a 91 hyundai accel and cost me like 100$ to have replaced back then though it was external to trans- why jeep didn't do this is beyond me.

 

Never too late to respond to a very old thread??????? Just in case someone ends up here in a search..........

To end the confusion, the Patriot DOES have a clutch master cylinder: https://www.tascaparts.com/oem-part...6043ab?origin=pla&gclid=EAIaIQobChMIlLvjx9LI1QIVmI-zCh1hpgFxEAQYASABEgLypvD_BwE

Number 2 is the clutch master cylinder. Number 3 is probably the slave cylinder.
