What is your question?
I replaced booster and mastercylinder. All 5 brake lines and calipers. System has presure until I start engine and then no brakes and pedal drops to floor?
I bled rear brakes and front brakes from the calipers with a vacum pump
The best way to get the air out is to have someone pump the brake until it`s hard and then bleed the lines till you have brake fluid coming. I wouldn`t trust a vacume pump..
