Clutch Master Cylinder Bad?

[knuss3807]

Hello,
2003 GL1800: My clutch master cylinder is not pumping any fluid. Is there a fix without replacing it?

It started with my clutch not completely disengaging. To my knowledge, I'm the second owner, the fluid has never been changed. I drained the system, removed and cleaned the slave cylinder, reassembled everything and now when I went to bleed the system, the master cylinder won't pump any fluid. The master cylinder was not disassembled, only wiped out to clean. Fluid level does not go down and there is no resistance on the clutch lever. I can see the piston moving back and forth. I don't have the snap ring tool to disassemble it but am willing to buy one if I knew what to get.

Thought I would run it by the experts before spending $200 on a new master cylinder assembly.

Just order a rebuild kit. At the Honda School we had to take them apart and put them back together and it is a really simple job. Clean the orfices, put new seals in and piston cleaned and everything back together. Fill with brake fluid and bleed and off you go.

I just did that to mine a couple days ago.

I replaced all of the rubber parts including the diaphragm under the top cover.
I also bought a new spring, just in case the old one "might be broken?" or just weak.

the total cost was very small... gave me piece of mind.

did the master and slave cylinders.
works good now

I will add to this chorus...I did mine as well. Rebuild it, its easy.

Thanks everyone! Rebuild parts are ordered.

You may find that the bushing on the clutch lever is worn as well. If you go to bike bandit and look up your clutch assembly its part #2.
$11 bucks or so from Honda.

Used OEM for all my rebuild pieces.
