A-Body Round #2- My '76 Scamp restore...

I did that way and used a bottle with hose filled with fluid about halfway worked great. The hose you connect to the bleeder loose. I taped the top hose in hole cap it's a vacuum seems to be easy fix. Oh chocolate milk from 7 eleven or QT small 12 ounce worked great lol! Obviously drink the milk first clean it out hahaha. The bottle lets you bleed brakes solo.
I also have a vacuum bleeder, works great for pulling fluid thru a dry system.
