I think I need new brakes for my car. What all should I replace?

Go to hospital get head checked to see if there is brain installed. After 4 years of leaking brake fluid do you not think something should be done.You are a moron and should not be on the road. You are a menace to the driving public and a stupid person for even having the ability to ask this question. Who the hell even gave you a key board and allowed you on the Internet? When brakes leak for more than a day , that means get it fixed. WTF do you mean it`s been doing this for a few years?
