Brake fluid?

[A4NA18]

I am driving, not even braking and all of a sudden the brake warning light goes on with three beeps.

It is usually when I turn a corner.

I check the fluid level and it is just below the middle between MAX and MIN.

I suspect a fluid leak but how do you check it? How much does it cost to replace all the braking system?

WHAT'S GOING ON?!

Have you checked that none of your brake pads have worn ? As a low fluid level normally indicates that there is a large amount of pad ware normaly not a leak.
