CMS Fluid Warning

[camos]

The other day I discovered something that I never knew. The "brake" fluid warning light came on but both brake reservoirs were full. What was down was the clutch fluid reservoir. Topped it up and the light went off. Assuming it was not a coincidence, it appears the warning also includes the clutch fluid.

It might be one of your "floats" in one of the reservoir is partially submerged. The floats have little magnets on them and activate a reed switch inside that black center thingie with wires exiting from the bottom. As the float lowers, it activates the switch telling you you're low on fluid. I don't recall the clutch having one...

Haven't noticed a float in the right reservoir. Will have to see if I can find it next time I'm in there....if I can remember that is.

It's about time I cleaned and flushed the clutch fluid so I'll check for the warning after emptying the reservoir.

Motivated myself today and flushed the clutch system. Looks like you were right, no float, whatever they look like. Checked the CMS after pumping down the reservoir and no warning. Case closed on that but still wondering about the floats in the brake systems. If they are sticky then the only apparent way to clear them would be to flush and flush and flush. I suppose a false warning might not be due to a sticky float but a bad connection between the reed switch and the CMS.

 

Had a bit of a traumatic experience flushing the clutch today. Pumped the reservoir down almost to the bottom, put in some fresh fluid and no more pump action. Pumping the lever moved only a tiny bit of fluid with next to no pressure felt on the lever. Disconnected the banjo at the reservoir and only enough fluid moved to almost get to the opening. Fiddled with it for 20 minutes with no positive results.

 

Starting to panic here, gotta go to work tonight.

 

Finally in a desperate move I blocked the reservoir opening with my finger and pumped the lever. It pressurized and when released, spurted a little fluid. Put the banjo back together and had pumping. I'm guessing some crud from the reservoir got into the valving or discombobulated an o-ring in there.

 

Fortunately the dash area had been covered with a towel. Did however find a few drops on the seat and the backrest.

Maintenance can be so much fun?
