Open the bleeder on your caliper and let it sit for a hour or so. Then try to bleed it if it doesn't work then you will have to rebuild it or buy a used or new one.

An easy/fast way to bleed brakes is: For Rear Brake 1. Fill the reservoir with DOT4 brake fluid and leave cap off of reservoir. 2. Crack the bleeder on the caliper. 3. Push down on the brake lever and hold down. 4. Stick thumb or finger over hole of bleeder. 5. Release brake lever and keep thumb or finger over bleeder (this keeps air from entering back into the lines). Remember to remove thumb or finger from bleeder when pressing down brake lever and cover bleeder when releasing. Continue this process until all air are out of the lines and a stream of brake fluid is continuous. On front brakes do one caliper at a time. Make sure that the master cylinder reservoir doesn't run out of brake fluid during this process or air will enter the lines. This will take a little time to start seeing fluid come out the bleeder so have patience and good luck!
