Need help bleeding brakes
can't believe I need to ask for help with this but I need help. Complete new system front to back every thing started out dry. Bench bled master cylinder, with vac pump started at furthest wheel and pulled fluid out wheel cylinder till no bubbles. Did the other rear then the two front calipers the same way. Drew a ton of fluid out and looked like I got most the air out as well. Go to press the peddle...... nothing!!!!! Zero pressure. Start back again at furthest wheel with vac pump now I can't get fluid out. What is the proper method with a vac pump? Keep the bleeder open and keep pumping? Or do you keep the bleeder shut, put a vacuum on it then crack it open? Is the master cylinder lid supposed to be open or closed? Thanks in advance, I've don't this before just never with a vac pump.
