Clutch master cylinder bleeding tip.

[full quack]

Hey all,

First you can all slap me for not taking pictures...sorry.

After reading up about the problems folks have had bleeding the clutch master cylinder after a replacement, it seems the main issue stems from the shared reservoir between the brake master cylinder and the clutch master cylinder. The biggest issue is the fact that the little side compartment for the clutch reservoir does not hold much, nor does it refill very fast....like damn near taking forever!! So you end up sucking air into the system time after time, very frustrating.

So...I came up with a solution that worked killer...at least for me.

I pulled the clutch master cylinder reservoir hose off the brake master cylinder reservoir, and temporarily plugged that port. Then I simply substituted a very large syringe that held about a 1/3 cup of fluid as a remote reservoir, that I shoved into the clutch master cylinder feed hose. I secured the syringe to a machinist magnetic base with some tape, so it would be secure and sit vertical.

Worked flawlessly, bleed the system in about 10 minutes. Then simply re-attached the clutch master cylinder feed hose back onto the shared brake master cylinder reservoir.

Hope this helps somebody out.
