Front brake lever not right

Hi all, didn't find anything on this subject so I have to ask. When I press my front brake lever in to stop the bike, it "kinda" sticks a little and when I give extra pressure, the lever "unsticks" and pulls back further than I want and the front brakes goes on harder than I intend. I then have to let up and "speed-press" on the lever to get the bike to stop at the rate I want. This is new to me, so I was curious - Is this a WD-40 fix or fluid change? Or????

Sounds like your master cylinder plunger is sticking, or you have a caliper piston sticking, not moving freely back and forth.

04-3,200 miles bought July 2011 with 928 miles. Loaded with acessories to many to list here, see my albums for more details! I also make a custom tank bib specific for the 750 if anyone is interested, ck my albums for some pics.

...suggest a fluid change would be a great place to start. I had problem with the lever not releasing completely....just enough to where the brake light stayed on. Drained / cleaned MC (tiny pin hole clogged) new fluid, works like new !
Hope this helps

...could also be as simple as road crud in between the actual lever and mount as well...I had it happen to a '68 Sportster of mine's clutch after riding 9 hrs in rain, sleet and snow...

I had the same issue and bought a rebuild kit. I have also had a singing noise for the past 10,000 miles at slow speed. However, when I changed out my front tire, the issues magically resolved. I can only conclude that a caliper, pad or piston was stuck. My recommendation after a fluid flush, is to remove the calipers and push the piston in slightly to possibly unstick them. Check the slide pins and clean/lubricate. Make sure the pads are free in their slots.

Aha - as soon as I finally do get to this job (been avoiding the sweat-house outside) this will be something I'll check. Thank you.
