Title: Clutch master cylinder swap.
Post by: Monster750ie on October 01, 2011, 04:50:03 PM
Hey everyone, I need to swap out my master cylinder and lever and wanted to know is anyone has done this. Can anyone give me a few pointers. I tried searching for a bleeding procedure and came up empty.

Thanks in advance!

use 'bleed clutch' as your search term and limit the search to tech.

I got 6 pages

Thanks, seems simple enough. Remove the banjo bolt, keep the line elevated, replace the master and lever, bolt the new master and lever on. fill with fluid and good to go.

As long as I dont drain the line I most likely wont need to bleed the line. correct?

You can try your luck but most likely you will have to bleed it at least at the banjo bolt.  I would bleed at banjo bolt first then at the slave.  Cover all painted surfaces and the dash as it is quite messy.

Highly unlikely that you'll get away without bleeding. There will not be fluid in the voids of the new master, there will probably be some air introduced at the banjo.

If you've got a way to push fluid in from the bleeder in from the slave you might save some hassle. But don't think you'll get away with just swapping on the new master.

+1.  Getting the last bit of air out at the master will take a little time.  I'd swap out the master and leave it overnight with the lever strapped to the bar.  If you're lucky the bubbles will work their way out into the reservoir.
