in my rear brake light switch not working?

I noticed today as i was backing up again the wall that my rear brake light doesn't work when i apply the rear brakes. I'm not sure if this was how it was suppose to be or not.

I can hear the front brake switch/relay do its thing and it works operating the brake light. I see the connection right under my handlebar. But for the rears, when i try to look for a possible electrical connection, i see nothing.

So i'm assuming that the rear brakes ARE NOT suppose to be activate my brake light. I swear my old GS500 had both activate it.

Rear brakes are supposed to activate the brake light.

Do you have aftermarket rearsets?

Re: in my rear brake light switch not working?

Mine didn't activate when I first got my bike. If you look behind the rear brake lever, there's a hook that attaches to the mechanism with an adjustment screw. If yours is like mine, you just need to tighten it up so that the hook gets pulled enough when you step on the brake. Mine's a 1st gen, but I'm assuming the setup is similar, should take all of 5 minutes to fix.

Re: in my rear brake light switch not working?

There should be a switch on a bracket behind the heel guard that is attached to the brake pedal by a spring with hooks on each end.
There's one big spring that brings the pedal back up after you push it down, but there should be a smaller spring as well that activates the switch.

If the spring is still there, you should be able to adjust the height of the switch and when it activates by turning a plastic captive nut that the switch body goes through.
The nut has a groove that fits in a bracket back there and holds the whole thing in one place relative to the pedal.

If the spring is missing, you should be able to find something similar at ACE or Lowes.
Measure the gap and how much adjustment windage you have.

Took a look through the bandit diagrams, but couldn't find the switch or even the brake pedal. Meh.

Re: in my rear brake light switch not working?

Here's a photo of the brake-side rearset:



Here's the back. The switch and spring bcj wrote about aren't in the photo, but the circle is where the switch sits in its bracket. The arrow is the spring that connects the switch to the back of the brake pedal.

When the pedal is depressed, both springs are activated: one returns the pedal upward; the other activates the switch for the brake light.



I photographed these over a year ago when I was dismantling the pieces in prep for powdercoating. Hopefully, they're coming in handy!

Re: in my rear brake light switch not working?

thanks for the picture. So i took a better look at this.

So the light DOES work, its just i REALLY have to press on the pedal, like all the way down to get the trigger to work.

I was playing around with the adjustment rod and there was no way i can get it to trigger on the brake light without having to stomp on it.

As some call me...tim said, there's a nut on your switch. This allows you to move the switch up (increase tension on the spring) or down (decrease the tension - for example, if the light wasn't turning off).

Since you are having to stomp down, you need to move the switch upward so that the brake light is trigger when you start to depress the rear brake pedal.

If you're already at max height and still have to stomp, you can always shorten the spring. Cut off 1/2" or so and bend a new curve at the bottom. (I had to do that with my aftermarket rearsets.)

Good luck!
