HELP!!! having clutch bleeding problems

**GSXR_BIKER** · 30th December 2007, 18:54

Hi All, I have an old GSXR750 '87, been doing up for the last 6mths, just repainted and cleaned Fluid clutch system, when I put back togeather, I cant seeem to bleed it, Fluid comes out the bleed tube, but clutch wont harden up, Think I am doing it right, even replaced the Master cylinder to see if that was the problem, Any suggestions?

Is it flowing out or spurting out ie still air coming out as well,can go on for quite some time.

Not really sure, sometimes nothing when Ive pumped the lever, then other times a bit of fluid and Air, then other times when I have tightened valve few air bubbles? Been pumping lever anb Bleeding for ages, fluid level in resivour dosnt seem to drop very fast at all, Really frustrated??

If the level is not going down much then keep pumping..probably not what you want to hear but by the sounds of it the thing is full of air.

Is the bled nipple on facing downward or upward? Air in the fluid will sit in the nooks and crannies at the top of the caliper, if the nipple is on the lower side of the caliper you will NEVER get all the air out....

If your unfortunate to have a caliper with the nipple on the lower side, unbolt the caliper and turn it up the other way, ensure though you have something clamped between the brake pads otherwise you might shoot the piston/s out..

Report back here after trying this method

Scrumpy....good on ya,havent had one of those for ages,interested to see how this pans out,if i read right he started with empty lines so a pumping he must go..and go....and go

If its been empty for a while you best bet is to use a powerbleeder of some description and pump some fluid into the system

like this one I prepared earlier

sure your not pumping the wrong lever

just kidding mate,30 minutes is way to long.what puzzles me is you say its not droping the level very fast.At what stage are you tightning the nipple?

**R1madness** · 30th December 2007, 19:38

this will work but be careful.
Go to a pet shop. Buy a 1.5 meter length of 6mm internal diameter fish pump air hose, attatch it to the bleed nipple at the slave (bottom) cylinder. Hold the top of the hose above the master cylinder. make sure the master cylinder is full and you keep a constant check of the level from here on. Open the bleed nipple. Suck on the hose keeping one eye on the level of the fluid in the master cylinder (dont let it get low) and the other eye on the clear hose making sure you do not get brake fluid in your mouth. When you have sucked fluid more than 1 meter up the clear hose the clutch will blead up as normal.
Happy riding.

hhmmm well patience is a virtue then my friend.. OORRRR get a mityvac, and pressure bleed it....Either way you started with empty lines, it is going to take a little while..
