Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

I would have thought bi-annual fluid changes would be fine. Thats what I do.

Maybe you forgot in March.

To be honest I change the fluid once in a blue moon, it won't stop the brakes working when the fluid gets old. Brake fluid is hygroscopic which means it absorbs moisture, it's still a liquid which is not compressible.
Just bleed it for starters, make sure you've got no weeps around the piston!

I was just watching a YouTube vid (good channel for picking up tips that can be applied to any bike) and he discusses the colour of brake fluid... maybe worth looking at?

Bit you'll probably be interested in is at 11mins and 15seconds.




(for those that don't want to watch it could be deterioration of the OE hose)
