Hey Richard Kirshy
Good news is that my bleeder screws were not rusted at all and I was able to gravity bleed all 4. Strange thing was that the flow of brake fluid was very slow on all 4 wheels even though I opened up the valve at least one and a half turns.
What does that mean?
Also, when I test drove the truck the brakes continued to make what I call is a “farting” noise. This only happens when I am just about to come to a full stop. I will look at videos right now because my suspicion is that my master cylinder is going bad.
