1989 Chevy Caprice pedal to the floor

Hi there,

thank you for the donation,

My first thoughts are that you still have air trapped in the system, I would start with bleeding the master cylinder and then the rear brakes then the front, always make sure that you never let the master cylinder run low on brake fluid, bleed into a clear container and keep an eye on the bubbles if the system continues to bubble, you will have air entering the system, start here and report how you get on.
