I noticed the other morning that the front brake lever has way too much travel for my liking , it felt spongy but the bike stopped ok. I don't find any leakage of brake fluid , and looking at the sight glass it's either completely full or lower than the glass. I tried shaking the bars to see if there was any movement of the fluid but don't see anything. Tried the old trick of compressing the lever overnight with a strap. But it did not improve on the travel or feel. I looked at a video about changing /flushing the fluid and it looks like a major job of body parts, windscreen, and mirror removal. Is there any other way to just see if I just need a little brake fluid. ??
