Motorcycle Repair: 06 Sportster Custom Rear brakes, rear brakes, master cylinder

Question
I just replaced the rear master cylinder on my 06' sportster and still can't get any pedal. I bled the brakes for about an hour and wasn't getting anymore air out of the line, but still no pressure. I couldn't find any noticeable leaks in the system. Is there something I missed? How can I get the rear brake to work?

Answer
There are only 3 reasons that you cant get a pedel. One is a leak and you said there is none, you have a bad master cylinder, or you still have air in the line. It takes along time to get fluid through the system since the hole is really small in the master cylinder. When i do it I use a vaccumn pump to pull the fluid through the lines
Good luck and happy riding
