T5060 flashing caution light/ trouble symbol

[1340]

I picked up a used T5060 this summer.
Now the caution light comes on and flashes 4 times, goes out, shows a trouble symbol, that goes out, then the caution light comes back on and stays on. The symbol shown is a circle with a drop in the middle. On either side of the circle is a short line at 9 & 3 o'clock that matches the curve of the circle.
There is also a straight vertical line on the left side starting about 11 o'clock, drops down to the centre of the circle, and has a small triangle on the end pointing to the centre of the circle.
I was wondering if anyone has an idea what the symbol means. The closest l could find was brake boost pressure low. I think that is for air brakes which I'm pretty sure l don't have. I think that is a European system.
I called the dealer and they have no idea what it means. I will try another dealer, but want to ask here also.
No leaks under the tractor and I did check the brake master cylinder. Both levels were above the minimum mark.
I 'd like to get this solved so l can start using the tractor again.
Sorry for the long post.
TIA.

I'm pretty sure it is the Brake Fluid Level light. The 2 outside curved lines represent brake shoes, and the drop is fluid. The line on the side with the arrow at the lower end would indicate low brake fluid.

Well done!
It appears you are correct.
I found the exact symbol l have in an online T6010 owners manual.
Brake Fluid Level low.
I didn't see it in my manual though.
Thanks for the info.
