Brake fluid - light sensitive ?

Extremely hot - extremely strong sun!

Touring in Australia 4 weeks, the brake fluid in the urine container changed from light yellow to orange. Is brake fluid light sensitive?

I have not had my fluid in my GSA change, but it has not been left in the sun much either. My Stroms fluid turned orange over about 3 years...yours change just while you were gone???

The brake fluid was changed before I rode through Australia. When I came back about 5 weeks later it was orange (the type the local BMW agent uses is almost clear like water when new, with only a very slight yellowish tint). The bike was ridden for weeks in extreme heat, many days around 100 F and more, parked in outside in the same conditions.

Not that there is anything wrong with the brake. But I was just wondering if brake fluid degrades under stron UV light or constant heat.

I would be more prone to suspect heat for the transition rather than UV on that short of span. Did the dealer offer any explanation?

Heat.

Again, not a problem, I just wanted to know. I take then it was the heat.

Under continous use, and especially hard breaking, brake fluid can heat up alot. I have had it literally boil on race bikes. And yes once it was heated up alot it started getting a brownish yellow...
