I was gravity bleeding the clutch on my S2000 and at some point I managed to run the master cylinder dry.


After that I ran two bottles of brake fluid through the system making sure that the master cylinder doesn't get low and I still got air bubbles out. Video below.

Is there a possibility that the air that I see gets in between the bleeder thread and the slave cylinder ?

If there is air left in the system, do I have a chance of getting it out with gravity bleeding or I'll have to use the two person technique ?

I'm confused since it seems like no matter how much fluid I run through the system it seems like I'll still get air bubbles.

Thanks in advance for help.

 

you can bleed the clutch yourself. just fill the MC to the top, pump 5-10 times and refill the MC without the MC resorvoir running dry. Rinse and repeat until air is completely out of the system, then tighten the bleeder valve back to close it up. Worked for me since forever without any issues.

 

a good way to do this is to wrap the resovoir with a towel and put a small funnel in it and fill it up past the resovoir to ensure you don't run it dry. Be careful though because brake fluid is hard on paint

 

If I pump the clutch with the bleeder open that's gonna get air into the system.

Or did you mean pump a few times and then open the bleeder ?

 

^^ No you wont. Its not like when you are bleeding the brakes. When you pull the clutch "up" it doesn't suck air back in. Keep the bleeder open. Trust me I just did this like a month ago. Pedal feel's like butter . Just fill it up, pump the clutch about 5 times, add more fluid, do it again. Repeat this process 5 or 6 times and then crawl under there and close the bleeder.

 

I see ... so that's the difference versus the brakes.

Is there a technical reason they implemented the clutch system that way ?

Now I understand why they say that the clutch pedal might not come back by itself and you might have to pull it.

I'll try it this weekend.

Thanks a bunch.

 

No prob. Just make sure the resovoir doesn't go dry during the process and you'll be golden
