Brake lever doesn't retract. Brake light misinforming other drivers

This use to happen to my 05.

I've since switched master cyclinders to GSXR unit and the problem is gone. I believe I tried adjusting the switch itself so that it would release properly. Loosen the mounting screws for the switch located underneath your master cylinder and push it as far from the lever contact point as you can.

If that doesn't give you enough clearance, you could slightly enlarge the holes on the switch to give you a little more room. It doesn't take much.

I'd also grease your lever's pivot.

Check your rear brake, and make sure that's properly adjusted.

Try loosening the bolt that goes through the lever.

And FYI, the switch will wear out... I wore mine out... took alot though.

Disassemble the lever, clean all the gunk and grit out, put some new grease in, reassemble.

Clean all the gunk out of the switch that you can.

bcj and others: Thanks so much. WD-40 around the assembly works!!! I sprayed little amount near the lever (where you can adjust the brake lever position (1-5); I pulled the lever away from me and sprayed WD-40 around it.

Hopefully this thread will help others who have/will have similar problems.

Clean an grease the pivot bolt. I wouldn't WD-40 it. It'll dry out after a few weeks of use and make it worse.
