My CRV Owners post: Okay, call me crazy but in doing routine maintenance on the fleet (16 CRV and 07 & 17 Pilots), checked brake fluid on all three. Pilots were both fine but CRV was a bit low and the filter and rim in the reservoir were green - like algae! Cleaned it out and topped it off but it’s time for a flush. Braking is fine; rotors good; pads have just a bit left before they need to be replaced. Any ideas?

Reply from the CRV forum:

"Not algae, what is happening is due to not flushing your brake fluid every three year per Honda's recommendations, see owner's manual. The inside of the brake lines are copper coated. When moisture accumulates in the brake fluid it corroded the inside of the brake lines and what you see is the copper oxides accumulation inside the reservoir. These oxides also accumulate inside the ABS module which can cause the valves to stick.
Flush your brake system!"

My response:

"Thanks for the explanation. Mine is a '16 so there is no "every 3 year recommendation" in my manual. And neither Honda dealer nor Firestone - both of which have been doing upkeep on the car for the past 4 years and 40,000 have recommended a flush or said anything other than that the fluid is good upon visual inspection. But since B1 just popped up, I was checking myself and discovered this, which is why I said initially that it is time for a flush."

I see the "reco" now - odd that dealer never called this out. Well, I stand firmly in the "Be Vigilant" crew!

Seems just a little over due for service.

Write the following with a Sharpie on your brake fluid reservoir: "Remember, brake fluid is hygroscopic." :)

Thanks NG! Dealer has had car 5 times in past 3 years for work and annual PA inspection and never called it out. Firestone actually replaced front pads and rotors just at 3 years and has also done annual PA inspections and did not call it out. For the life of me, I can’t understand either of them passing on the opportunity to advise me right and/or make some more money. I usually do my own pads and rotors (where needed) but I leave bleeding to the pros, especially on the wife’s ride! Service scheduled! And it’s annual PA inspection time for the entire fleet too!
