I bought a 2012 S10 that has been in storage for 3 years at the dealer. The color of the Brake fluid is not clear but I would say clear brown (looking through the rear brake reservoir). Is this the normal color? Thanks.

Different brands vary. It can be nearly clear, amber or even blue. The fluid is clean, which is good, but brake fluid is hygroscopic, which means it absorbs water over time. Normal heat cycles from braking help to reduce this effect to some degree, as does storing the bike in a climate controlled environment.

It's likely fine, but understand that the commonly accepted practice is to change brake fluid at least every two years to prevent that moisture content from getting high enough to cause corrosion in places where fluid can sit even under use, like the ABS valve block.

The fluid is normal. Ride the bike, enjoy it and flush/bleed the clutch and brake systems next spring. The most likely thing is that it's been stored out of wet/cold conditions and the fluid won't have enough moisture to worry about between now and next spring. After that, you'll know how old and how many miles are on it, and can go from there on what feels right to you.

Hope that helps.

Thank you Eric. I may just change all the Brake/Clutch fluids at the 1000km mark. So far the brakes has been superb, heaps better than my Versys 650.

I will add this, should you change the fluid and therefore open the reservoir, make sure you have the exact cross-head screwdriver for the job, anything outside the exact fit may cause the head to foul, also, when reinstalling do not over tighten and even add the tiniest dab of grease to the screw hole to ensure the screws do not seize, making sure that it does not go in the reservoir goes without saying, there is no pressure from the reservoir. When you do change, try to get a syringe and suck out as much of the old fluid first and replace with new before bleeding, thus ensuring new fluid is bleeding down from the get go.

2 years and or every break pad change.
The stuff is cheap and you can clean the grunge buildup on your pistons as well.
These breaks have to be the easiest to change ever the rear a baby can do it. :p
