I'm flushing my old factory brake fluid out with some Valvoline Synthetic, and this greenish algae-looking gunk keeps floating to the top of the brake master cylinder reservoir. I keep having to suck it out of the reservoir with my mighty-vac. Anybody else ever had anything like this happen? Anybody have any idea what it is? I've never seen this type of thing before...

Thanks,

Yep, seen that before. No idea what it is. Something in the fluid congealing, I guess.

Moisture?

Changing brake fluid on an 06 - seems a little soon to me.

^^^Wanted to flush it before the auto-x/track season started....

Figured it out: I flushed the clutch this morning. As soon as I poured the Valvoline Synthetic in on top of the Honda factory fluid, the green-gray stuff appeared. It seems to be some sort of reaction between the two fluids. I made sure to run a lot of the synthetic through the brake and clutch system, hopefully I got most of the old stuff out. Interesting...

Thanks for the help,
Eric
