I was doing some maintenance yesterday and decided to check the front brake fluid. Based on the site glass, I was concerned that it was over-filled since I never saw a bubble when turning the bars. When I opened the cover, I found a white piece of what appeared to be foam floating in the reservoir. It's cutout as if it was designed to fit and was wondering if this was something Honda added after 2006? My 2006 ST didn't have this. The service manual that I've got is for the 2003-2006 models and doesn't show anything below the rubber diaphragm.
Thanks in advance.
