So I have a problem with my brakes. Just to give you a bit of history the truck is getting a sas done to it and so the truck sat parked for about 10 months. The flexible brake lines were removed about 2 months ago. So today installed the new calipers on the front axle and new flex lines front and back. We filled up the reservoir and bled the brakes in the proper order as per the manual. Did it twice just to make sure all the air was out. When the truck is turned off the brake pedal goes about half way, will build up pressure and stay there nicely. All seems fine. The problem starts when the engine is started. As soon as the engine is started the pedal goes all the way to the floor and when pumped I can never get it to feel right, seems to slowly go to the floor. When the engine is running we saw some air bubbles coming up to the fill port where you add brake fluid. We checked there were no leaks, the oil does not drop, the check valve between the air intake to the booster is fine(allows air to flow one way). When we turn off the engine and then pump the brakes it seems to go half way with good pressure and holds in one place when depressed. When the pedal is depressed and the engine is started it gets sucked to the floor. At this point not sure what the problem is. Any suggestions would be nice. The funny thing is that the brakes worked great before I took it off the road.
