rear brake switch going crazy

I've narrowed the culprit to why my brake lights keep going on without using the the brakes. The rear switch got water in it and is shorting somehow.

I'm on the road and need to disconnect it for now. Do I do it from the top of the switch where the wires go in or do I unplug it where the wires lead to (somewhere underneath the seat or engine)? Help!

I would unplug the switch and secure the wires with a zip tie.

Does the white tab the two wires go into (the switch) come out? I don't want to break it if it doesn't

If you trace the wire up there will be a 2P connector that you can unplug. When you get a new switch there will be a cable attached with a 2P connector, you you could just cut the wires at the switch and tape them up.

When you replace it go with a hydraulic switch, much more reliable.

Thanks Mike, I need one of those hydraulic deals. Where can I get one of those?

Here's mine, I was thinking that white portion with the clips come off. If not I'll probably end up cutting it like you said

I need one too. My rear switch stopped working a while ago.

You can pull that white piece out but pretty much all of the internals of the switch will come out. If I recall the wires are soldered inside anyway.

Here's where I got my hydraulic one;

and a boot to make a little cleaner look.

For those of you who have working rear brake switches, I opened mine up, cleaned up the contacts with a small file then added plenty of dielectric grease in there. That should prevent corrosion for a while and make them last longer.

How did you get it apart?
I'm bettin its easy but the time I looked at it I couldn't budge it easily and I wasn't have a good day so I thought it'd be best to leave it, but it does work.

There are a couple of slots on the side where the white piece has some tabs that lock into the housing. I took mine apart and cleaned it up, but it looked pretty worn out, so I went hydraulic for a replacement.

Couple of pics of the internals

I will be switching to a hydraulic switch once the oem one fails. I know what I did just prolonged its life

I had the water and gunk in the rear brake switch ages ago. I bought another Honda one and it appeared they had modified it to be more waterproof.

Interesting. Would you mind posting pictures so we can spot any differences if possible?

You could silicone the top part where the wires go in, underneath where the pin comes out is another story. Interested in pics as well.


Thanks for the heads up Sean. I'll grab one of those in the spring, I've got no problem running without a rear switch for now

This will also work. The spring will have to be cut down to fit. Not sure of the longevity. At least the top part seems more waterproof.

Must be some issue with the rear brake lite switches on the 9'ers. It's the only thing i had to replace on my '07 since I've had it. Tried to clean the contacts but they were too far gone with corrosion from moisture entrance,.

Love this web site. Thanks guys.
