Rear brake light and pedal adjustment? - SV650.org

08-02-12, 07:53 PM

Evening, First post in this section, so be gentle?

After I dropped my bike in the snow at the weekend, I ordered a new brake pedal and fitted it, brakes work fine etc, however, I cannot get the brake light to activate when the pedal is pressed, now I don't think I've moved the master cylinder, or the bolt that adjusts the pedal height, so what else could it be, the spring looks like it's maybe 5mm short and doesn't pull the switch to the on position.

I'm fairly sure I've got the spring in the right place, it's hooked onto the same hanger as the pedal return spring, is that the right place?

I've given up for the evening, it's too cold and I don't have a garage, I'm irritated by my failure!

Any help would be great, by the way I've searched the forum but can't find a thread that tells me where it goes, and the Haynes manual is crap!

Should say it's a K2.

Is the switch not threaded with a locknut? Try pulling the spring only (to get more travel) and see if the light comes on. Try spraying with copious amounts of wd40.

Yep, the switch has a thread and a plastic adjuster nut on it (curvy does anyway, not sure about the pointy). Bit of a swine to get at but that's how you adjust it.

On a pointy, mounted behind the heel guard is the rear brake light switch. After replacing the lever you always have to adjust as it never seems to stay the same. The switch is threaded on the outside and an adjuster screws up and down to raise/lower the switch. Just raise the switch and then screw down the plastic nut a few turns and then retest brake light. You just have to get the balance between light not coming on when the pedal is pressed and being on all the time, even when pedal is not pressed.

Hope that helps a wee bit.

I'll have another mess with it tonight after work, it's a bloody nightmare getting my hands in the adjust the switch!

I've checked the switch is working properly by pulling it etc.

Such an irritating design!

Finally sorted it out! There is a method lol, I found it easiest to hook the bottom of the spring in first and then the top bit in!

Thanks for your help guys
