I have all drums and I just put on a new reman master with an 11" chrome booster to make the drums more useable. I used fuel line hose and connected the booster to a vacuum on the carb with a couple 90 elbows to make it clean looking. I went out yesterday and bled each corner. Started the car and no brakes at all. Took the cover off the master cylinder and when the brake pedal releases bubbles come out of the rear section of the master. Did I do something wrong or does this just mean there is still air in the lines somewhere? Also if there was air somewhere would the brakes not work at all?
