I'm assuming there is no such thing as a dumb question on this page but I need to know what to do. I've pulled the front brakes, replaced cylinders, fluid did pump out of lines before reattaching. got it all hooked up and now there is no resistance or pressure on the brake pedal. Filled the master cylinder but still, no pressure. What am I doing wrong. No leaks. Never done brakes and haven't bought manual yet so I'm depending on you all.
