How do you bleed a master cylinder on 94 Chevy silverado truck?
If it's not a new one, you should be able to get all the air out
by bleeding all four corners beginning with the one furthest from
the master cylinder. In other words, RR, LR,RF,LF
A new master cylinder comes with instructions for bench bleeding
before installation, but it doesn't sound like that is what you're
asking about.
