Since we had to remove the front calipers, they will not work unless properly bled with fresh fluid added. Start by attaching a clear plastic brake line to the caliper bleeder on the brake furthest from the cylinder, and then fill the master cylinder with fluid. Have someone depress the brake pedal slowly until they encounter resistance; at this point they will hold the pedal down while you open the caliper bleeder to allow air and fluid to flow into a catch bottle. Keep the master cylinder filled, and repeat the technique, pumping the pedal once and opening the bleeder until the fluid runs clear without visible bubbles. Tap the calipers with a block of wood to dislodge any air bubbles inside, and move from wheel to wheel bleeding the fluid in the calipers. If the pedal feels soft when you are done, repeat the process. If you are concerned about the final result, stop and seek professional mechanical help!
