Hello my name is ***** ***** welcome to just answers! I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required. If I don’t answer right away or quickly in conversation I am helping another customer or have stepped out for a moment and will respond as soon as I can. Ok lets get started!

Turn on engine, wife pumps brakes several times the holds to floor while I turn screw to bleed. Usually after I get fluid, I close and she releases brake. Do several times but wait 15 seconds in between each attempt.

oh wow so your not getting anything with full pressure at caliper?

Customer: replied 1 month ago.
No, and nothing in the line going back to master on that front side back.
Expert:  TECHPRO49 replied 1 month ago.

So I would pull the line going straight to the master as see if your getting anything there and that would rule that out if its a master or not

Customer: replied 1 month ago.
Umm already said I did that. It's not the master cause I get fluid from other brakes
Expert:  TECHPRO49 replied 1 month ago.

did you check the valve that splits off and goes to both calipers? its more so like a splitter block

Customer: replied 1 month ago.
Don't have a splitter. They are separate lines and the lines are clear.

Do you know anything about the Silverado 2500 diesel?
Expert:  TECHPRO49 replied 1 month ago.

so if you can trace the low fluid flow to the ABS system, the bphv which is the piece in the middle of the picture I sent could have some debris in it and may need to be cleaned, I would pull that and inspect for any issues, but when reinstalling it will need to be bled by a scanner after doing a primary bleed on the system

Expert:  TECHPRO49 replied 1 month ago.

that unit controls individual flow to each caliper via a solenoid and by the slightest amount of contamination will cause issues
