you will have to bleed the system. If you have a brake bleeding vaccum pump this will go a lot faster. Otherwise it can take some time and a helping hand will help. You won't need buds unless you start the engine or turn on the ignition and the nanny senses brake problems. If you have done this then you know how but the best way is get some clear plastic tubing that will fit over the bleeder valve. Fill the resevoir and pump the brake pedal. Refill the resevoir as the fluid goes down. It goes faster if you bleed the connections of the new line from the top down. Repeat the pumping and when you feel pressure open the connection while holding the pedal down. You must protect the areas around these connections with some rags. Brake fluid is corrosive and will spray out with the air in the line. Follow this proceedure on down to the bleeder valve on the caliper. You can also just do it all from the bleeder on the caliper that way the air and fluid will travel through the tubing. Keep doing this till your brake pedal is back to normal and the fluid has no air bubbles....
