Thanks for looking. I have a 2007 Suzuki GSX-R 600 and my brake light isn't working. I turn on my bike and the brake light stays on.... Any ideas? Hand brake and foot brake don't do anything.
Either your rear brake light switch or the micro switch on the handlebars has gone bad or needs adjusting most likely.Check them with a multimeter set for continuity.Apply the probes to each side of the switch contacts.The meter should show infinity unless the brake lever or pedal is applied.
Make sure the rear brake petal is returning to the up position fully. Lift up on it and then see if the light is still on. If not, you need to make sure the return spring isn't broken or lube or clean the brake lever pivot shaft so it will return all the way.
i'm undecided on an old Honda if the rear brake is handbook or hydraulic. no count, first seem for a change close to the brake pedal/lever, it would be common to become attentive to because it feels like the impartial start up turn on the seize pedal of a handbook transmission vehicle. If there's no longer one then there's a hydraulic brake line tension change someplace. in view which you assert shaking the motorbike disengages the brake lite i could wager the Honda has a handbook change interior the brake line linkage.
Sounds like your rear brake light switch is sticking on or needs adjusting. If you are in the uk, & ride in autumn to spring, am 99% sure that's what it is. The cure is cheap & easy. First, check the adjustment, & that the switch (that black placcy thing between the rear brake fluid cylinder & pedal, usually attached with a spring at one end) is attached at both ends. Then spray WD40/GT85/Duck oil onto the switch, esp at the plunger where it goes into the switch. Avoid spray going onto the disc or caliper, for obvious reasons. Work the brake a few times so the spray gets into the switch, & you should be ok. Hope this helps, please post again if it doesn't. EDIT/PS If this doesn't work, I agree with Andy about multi meter tests on the switchgear.
