Is My Clutch Master Cylinder Stuffed?

[stuartlaw_78]

Hi all,

I've had a clutch problem where my clutch would slowly get worse and worse where it wouldn't select gears.

It gets to a point where I can't engage gears but when I look at my master cylinder, it's still full!!

There was a damaged line but I have now since replaced the standard lines with a braided line that gooes straight from the master to slave. I have read the tutorials and tried bleeding the clutch but no matter what I do, I can't get any pressure on the pedal!!

It's almost as though the pedal isn't prooviding anny hydraulic pressure sommehow????

It just flicks to the floor from the spring and I need my hand to get it back again.

I thought there was just air iin the line but I've tried opening the nipples one at a time and nothing comes out! Even the nipple at the master cylinder doesn't have any liquid coming out of it when I pump the pedal..

What's going on people?? Any ideas?

PLEASE HELP!!

I had the same problem with my old R32, And it was the clutch master cylinder.Once we emptied it out it was full of shit and it wasnt functioning properly.However its not a major job to pull out and off memory the master cylinder is identical to one of the Nissans sold here as I was able to exchange it for a reco one...I am pretty sure it was either a Nissan Navara or 300 zx....I think they are all the same..And it was surprisingly cheapBest way is to whip it off and run it over to a place in your area that specialises in them..they will quickly find a match

check the pedal box as well as mine broke on me also...they are pretty tacky things just spot welded together.You will be able to examine that if you lie on drivers side floor with your head right where the pedals are you will be able to see the pedal box and how its bolted to the firewall.Get down there and work the pedal with your hand and see if the metal fram of the pedal box moves excessively...If its stuffed they are preety easy to change if you got a socket set...But a new pedal box you will only get from a jap importer...Hope that helps!!!!

Thanks mate, yeah, I emptied it out again and there is crap in the bottom of it so chances are, it's stuffed.... it's the original so it's done well! :-)

I may buy a new one, they are only $120 from Nissan...

Thanks for your help and info...
