Title	Mercedes W123 Brake Fluid Flush/Bleeding
Introduction	Did you know that brake fluid is [http://en.wikipedia.org/wiki/Hygroscopy|hygroscopic]? In short, this means it literally draws in water from the surrounding environment.This leads to the potential for corrosion in your car's brake system if you leave the brake fluid for too long. It's a good practice to change it every other year.The way to do this is to flush the old fluid out of the system using fresh fluid. When you've finished with the flush the system will be full of new fluid.The process is basically the same for bleeding the system after you perform some work that opens the brake system to air, such as replacing a brake line. The system must be free of air to work properly so you will need to remove it by bleeding the system.Please keep in mind that brake fluid is corrosive to paint so try to keep it from getting on your car's paint. Be sure to rinse it off if any does land on your paint.Also, always remember to wear gloves and glasses and any other protective equipment you feel will help keep you protected when working with automotive fluids as most are toxic or caustic to some degree. In the same vein, always remember to catch the fluid in an appropriate container and to dispose of it properly. Your city, county or other jurisdiction can help identify the best way to dispose of it.
