I have tried and tried to bleed the brakes on my rx7 fd with a ls swap with a vaccum pump. The cars has a new master cylinder new calipers and all stainless lines. I can get the brakes to bleed tell I see no more air in the line to vaccum pump and they will be hard with the car off as soon as I start the car the pedal gose to the floor and you have to pump it a time or two to even get it to want to stop from idle the car dose have a abs delete so there isn't air being trapped in the abs unit any help would be great thanks
