Pontiac Repair: brakes, air bubbles, resivior

Question
ok already bled master and tried bleeding the lines. im getting no pressure from the rear chamber line on the master. bled master a few times but still no pressure. checked the depth the rod was pushing the master and found no problems there.

Answer
What model car is this? did you replace the master cylinder? Did you "bench bleed" the cylinder before you put it on the car? If not then that is the issue The master cylinder is bound up with air. you can get a "bench bleed" kit at any parts store it a bunch of fitting to screw into the holes where the lines go and hoses you run back into the resivior of the master cylinder and then you just stroke the cylinder untill you have no more air bubbles comming out of the hoses. then attach the lines back up and bleed the brake system. Good luck :)
