Question about 2008 Suzuki GSX 1300 R Hayabusa
2009 Hayabusa all light work but brake light. It doesn't even click when brakes are applied help, please @
Hi, Adamchinn79 before diagnosing any brake light issue always check the bulb and fuse first for integrity a brake light staying on is usually caused by the front brake light switch, which is mechanical, not disengaging. On early models moving the throttle control housing closer to the front brake master cylinder is the main fix. On late models, the switch gets tweaked and needs to be realigned. A brake light that does not come on when the brake lever is applied can be caused by a faulty switch or no continuity in the wiring at the switch. The rear brake light switch is hydraulic and it is extremely rare to malfunction in a closed circuit condition causing the brake light to stay on. Usually, rear brake light switch issues are caused by no brake pedal free play or a sticky rear master cylinder piston. A brake light that does not come on when the rear brake pedal is depressed can be caused by a faulty switch, air contamination in the brake line, or no continuity in the wiring at the switch. Finally, most tail light wiring harnesses run under the rear fender held in place by spot welded clips. Worn out rear shocks or lowered suspension can bottom out causing the rear tire to come in contact with the wiring harness, rubbing the insulation off, exposing the bare metal inner core, allowing it to break or short out.

I've got the same problem on my 08 Busa. Both times happened after turning left. The second definitely happened when I turned on the left turn signal. The 4 way flashers worked after I replaced the fuse the first time. Perhaps the left turn signal worked a few times between replacing the fuse the first time the second time it blew. I looked at the left handlebar switch and can't see a problem in it. Next, I'm going to trace some wires.

Hi, the lever should not go all the way down, sounds like you have air in your brake system, check your brake pads, if they are ok than bleed the rear brake system, the lever should never bottom out.
