Brake light Switch adjustment

[Big_Zed]

Hi all,

My brake light is continually on and it stays on when lever and pedal are both fully released.
Has anyone needed to have a go at doing an adjustments themselves, instead of taking back to the dealer?

Keen to see if this is possible if not too technical.

Cheers,

Hallo
Probably the rear brake light switch is set too tight. The switch has a knurled nut with which you can adjust it, I had to do that when I put my brake pedal further down. However, the knurled nut is not so easy to reach, unfortunately. But the adjustment itself is simple.

Ah, that is probably it ratman, Thanks. I only noticed it after adjusting my brake peddle down also. Is it the nut which is half under the rubber weather proof sleeve that just needs loosening off a bit? Would you have a pic?

 It is the spring with the plastic nut, which is the brake light switch. A pin with a hole where the spring is hooked. Relax the upper nut counterclockwise, the brake light switch is relaxed, turn so far that the spring is slightly on the brake pedal, then counter with the lower nut. I'll try to send a picture.

Hello everyone, I am having the opposite issue with my 2020 ZH2. When I pull the front brake handle the light isn't coming on consistently. Sometimes it works, others it causes the brake light to flicker, and sometimes it doesn't work at all. Any suggestions? The rear brake light switch works fine for me. TYIA!!

Hello,
the "contact" is a microswitch, a simple on-off switch. Is it the original brake lever or one from the accessories? Is it adjustable? then just try a different setting. Have you ever tried whether it depends on how hard you pull the lever?  If it is an accessory lever, it may have different dimensions than the original. Maybe the switch is loose in the bracket. otherwise I would first spray the switch with contact spray, but it can of course also be a plug connection somewhere in the wiring harness.

I have the original brake lever on the bike. I did try pulling on the lever harder, softer, pulling slightly up and down when I pull it, and checked to see if the switch is loose in the bracket. I will try to disconnect the switch and check the contacts. If none of that works, it looks like the replacement part is just under $25 from Kawasaki. It will not be fun trying to find the plug in the harness and replacing it.

This miniature micro switch is not only for brake lights but also cruise control and is located at the lower part of the lever, it is extremely flimsy to say the least, but if you can activate and engage the cruise control then the switch is OK, if you find that you can activate but cannot engage cruise control then the switch may well be damaged, faulty or you got a break in the wire...
