Some posts on radiator service
There are other reasons to get your brakes checked. Brake lines can go, and this is very dangerous if not fixed right away. Under no circumstances should anyone drive a car with a broken brake line, not even if it is the back brakes versus the front brakes. If you need to replace the brake line soon, the person checking your brakes will say so. How can you tell if you have a broken brake line? Braking will take much longer than usual, and require putting your foot down hard on the brake peddle, which can potentially be a very dangerous situation.
