1954-Chevy, 6400, I wanted to bleed my brakes but I may have a problem. I have the shop manual for my truck but I am confused about the bleeder valve at the wheel. The manual talks about a valve (screw) all I can see is a hex nut that seems to be hollow. Is the screw missing or do I try to unscrew the small hex nut? How do I attatch a hose to the valve for the bleeding process? At this moment I am not worried about the hydrovac unit, which I am currently bypassing. Thanks for any advice.
