if all have been checked and good, then the reservoir cap is the issue. It is a known issue with the brake reservoir cap with the float.

Take out the float and wipe it off and reinsert. Probably need to get the brake fluid service done. Mines did that but went away for a bit when i wiped off the float filter thing.

I wsa getting this off and on a couple weeks ago. Thought it was the brake fluid level, but it was fine.

BUT, I did notice that the last time the Brake Fluid cap was put on, it was oreinted so that the wires for the fluid sensor were stretched/twisted toward the front. I re-did the cap so the wires were on the back side, closer/direct to the connection. Problem solved.
