Jeep brake & clutch issue after master cylinder change
Discussion
Well we had the clutch master cylinder changed last week on the Patriot CRD and initially all seemed good, however 100 miles later we have the same clutch issues but the brake pedal is now weaker as well
Is there anything on the clutch master cylinder that could have caused the issue with the brakes too? We're taking it to a Jeep specialist once we figure out how to get it there but was wondering if it could be something simple to fix at home before we go.
Thanks

I found this post on the Patriot forum, but don't see how the brakes and clutch could be related as they only share the reservoir?
"Just to conclude the problem to this original thread was the brake master cylinder. It was difficult to believe as my original problem was no pressure in the clutch pedal and the brakes worked fine. After a couple of days sitting though the brake pedal also had no pressure. The clutch master cylinder, as posted earlier in this thread would seem a very simple connector and not really too much to it to go wrong in my opinion. The brake master cylinder though is basically a syringe forcing fluid round the system and on mine I had fluid evident where is shouldn't have been able to get to so obviously had a seal leak. Replaced this and bled both brakes then clutch and all was good.
I hope this helps someone else out there, I hate it when someone asks advice and time off other people then doesn't bother to post the cure."
His symptoms are exactly like ours, so wonder if there's anything in it!

Maybe a daft question but have you checked the fluid level?
If you have replaced the master then normally I'd suggest changing the slave at the same time, when the master fails it will over pressurise the circuit and pop the slave off its seals. It drains the reservoir and let's air into the brake master cylinder.

That's the odd thing, the fluid levels are not dropping which is why I wondered if the quote above was of any note.
We are getting the slave cylinder changed next week hopefully, just waiting on the AA and garage to have matching slots
Thanks for the response, does the gearbox definitely need to come out or do you think it's accessible from the top of the engine?
Thanks again for your help
