As long as the arm on the valve moves slightly when you press the brakes,and then returns when you release them,it's working.It's only the arm that seizes usually.
I'd go for a full brake check and fluid change as said above,I think you'll be surprised by how much better they will be.
I'd rather push my Alfa than drive a BMW....
