FYI: Clutch Master Cylinder Problems

[raist60]

Just thought id post for anyone else that runs into similar issues.

After a clutch bleed i had lost all clutch pressure and the pedal would fall to the floor.

After searching high and low for a new master cylinder the best i could find was Nissan for 170 and 3 weeks delivery. Didnt want to go with that.

Couldnt find a wrecker with one so...

I rang nissan again and they have Master Cylinder rebuild kits for 30 dollars available in aus as they are used on other aus made cars. This has fixed the problem for a very small cost.

The only thing the kit will not fix is a destroyed bore.

Cya,

Thanks for the info,......seems strange that bleeding the clutch would kill it ....are you sure you didn't get some air in there.

The reason why master cylinders die during bleeding is because there is no hyd. pressure you can over throw the piston (Move it further than normal) where there is usually dirt and other crap which destroys the seals.

We tried bleeding it for about 2 hours before we realised the master cylinder was ****ed. And now after the rebuild kit the clutch works good.

Um, you can also just get a brake/clutch shop to rebuild it. About 80-90 dollars, they bore it and put a new rubber kit in there so its pretty much like new.

Is the master cylinder hard to get out? Any hints??

Or should I just drop it off to someone?

even if the bore on the cil is pitted badbly u can get it reslee ved with a stainless sleeve and it will last for ever . a lot of brake shops do it

They usually just give it a hone to get the bore shiney to make a full contact around the outside of the bucket
