Adjust front/rear brake light switches?

I want my front brake light switch to be more like a car's so I can tap it to back people off without really engaging the brakes. I have to be moderately on the brakes right now before it clicks. Is there an adjustment?

Also, my back brake switch is adjusted all the way out and it still doesn't engage unless I stomp it. I'm thinking about replacing the switch's spring with something shorter. Can I just use some strong wire or does it have to be a spring?

not sure about the switches but I sometimes use the left arm bend at elbow arm down, that means stop. Drivers usually back off... Or make beleive you are grabbing things out of your pocket and toss them in the air, that backs them off too. One that works for me is driving with no hands as well.

good luck

If you don't use a spring on the rear switch you risk breaking it. You can just shorten the spring.

As I can't remember his the front switch works on the bike , I'll let someone else answer that one.

I am just going from a blown up parts diagram in the Clymer manual, no "hands on experience" for me working on the master cylinder.
It appears to be a simple on/off switch with no adjustments possible.

It is strange that your front brake engages before the brake light comes on.
I just checked and my front brake switch clicks and the brake light comes on as soon as the end of the lever moves a half inch or so, definitely before any hydraulic pressure is felt or brake is applied.

Possibly the switch is sticky and needs to sprayed with some electrical contact cleaner or brake cleaner, or it is worn out and simply needs to be replaced.

The front brake switch at the MC is removable with just 2 small phillips screws....and as Hoss stated, could just need a good cleaning (I suggest CRC 3-36)....the light should actually come on before the front brake engages....the rear is adjustible....but still, the light should come on before the brake engages....front OR rear....

Yeah, I looked at it today and the rear brake spring obviously keeps it from breaking the switch. I might fab something up.

Is the front brake switch a push or pull type? If it pushes, I could just shim it a little. Yeah, it only takes 1/2" or so of travel at the tip of the handle, but at that point my brakes engage more than I want if I'm just flashing my lights.

I think the little pin is spring loaded from behind, inside the switch, to push out when the lever is pulled and brakes applied. No way to shim that.

i would spray both switches with WD-40 to make sure they are moving freely before you go messing with altering anything.
