hydraulic front brake stoplight switch

[newold81]

I recently purchased an 81' GS850G, and I noticed that I've got brake fluid leaking from the right side front caliper. Not cool!
So my plan is to pull both front calipers, and replace seals and pads as necessary.
I'd like to install a hydraulic front brake stoplight switch while I've got the front brakes disassembled. (Per Mr. Stefnwolf's advice, "OVERHAULING BRAKE CALIPERS GUIDE".) My stock front brake stop light switch doesn't work.
I believe he's referring to a "Banjo Bolt" type switch.
It looks like there's two options, 10mm X 1.00mm and 10mm X 1.25mm.

Does anyone know which one would be correct for my 81' GS850G?

Would it be easier to replace the stock front brake light switch?

Thanks for the help!

10mm x 1.00mm

You can pick it up from Z1 and they'll list that information on their website. And it really depends on what you want. Both ways are easy and relatively the same price

Personally, I would vote for replacing with the OEM type switch.

Although the hydraulic switch is ultra-reliable and has no moving parts, there are times that I want to flash the brake lights a time or two, without actually applying any pressure to the brakes. With the hydraulic switch, you can not do that.

Just my opinion, but you are certainly entitled to it.

By the way, I think it's easier to change out the stock switch, too, especially if you don't have the brake system all apart.
Since yours is already apart, it will be a coin-toss.

Great point Steve!

I just ordered an OEM switch on eBay.

Thanks for the advice folks!

Take care with the eBay switch. I used one, and after a few days, the brake light was always on, and I couldn't adjust the switch to correct the problem. Not made to original specs, apparently.

Thanks for the heads-up, I'll be sure to pay close attention.
Hopefully I don't get a bum switch.

There is a back brake switch as well.... :-\\\
