Title: Clutch leaking break fluid
Post by: casper on August 12, 2015, 03:57:00 AM
Good day my good fellow FJ lovers

I've got a Q.

My 1100 is leaking breakfluid from the bottom section, (there where the bleed Nipple is) but it is coming from the inside of that piece, not from the Nipple. I blead the whole clutch system through with fresh fluid, but it is just gradually becoming worse.

What can I do here, and which newer bike parts (master cylinder for bottom) will fit here?

Thanks guys.

Sounds like clutch slave cylinder shaft seal leaking.

Seems ro be a fairly common issue on the fj's.

I believe the seal is replaceable?

Yes, and fairly easy to do too. Here's some info...

His slave is leaking BRAKE FLUID therefore the slave seal is bad or slave and seal worn out... shaft seal would be engine oil?

?

I think I supplied the appropriate link for parts (to cover the slave repair, and the engine oil seal), and info for reference to get a new slave if necessary.

My guess person became puzzled the moment shaft seal was mentioned
