Daily Driver DOWN!!! HELP!!! NO BRAKES!!

[v2500burb]

Just installed a new brake booster and master cylinder combo
went to bleed the lines and the back bleeder valves are rounded from previous owner
Suggestions???
Do i need to replace the brake cylinders??
As of right now I have NO brakes!!!

If you can figure out a way to get them out you can just put new bleeder screws in, whether you want to use a vise grip orrr maybe try getting a socket on it maybe with hammer? Haha worse case scenario you can't get them out and you have to buy wheel cylinders which aren't very expensive.

I am LOST....
I installed a brake booster master cylinder combo....
Bleed brakes from closest to master cylinder back....(finally got the back loose)
I fire up the truck and the pedal goes straight to the floor with a slow return

I'm not going to lie
I've never done this before
But I've gone through 4 12oz bottles of brake fluid

Should I start the rotation over?? (Closest to master going to furthest??)

I'm using a suction bleed tool....
Is old school manual better?

You should have a friend with you and have him pump the pedal and hold the pedal when you say stop then you crack the bleeder and repeat. Start at the right rear then left rear and then right front and left front.

No it doesn't have to be running and is your check valve good? And the vacuum hose to it?

Got it!!
It had a HUGE pocket of air
It actually stops when you press the brakes now
Before I had to pump to get her to stop
Not to mention the squeal of the diaphragm going/gone bad
Thanks guys/gals!
One more project under my belt

Uh.. brakes are bled furthest from master cylinder to the closest not the closest to furthest.

Also did you bench bleed your M/C? Has to be done regardless.

Also if you are a one man doing this either gravity bleed your brakes or get a 1 man vacuum kit for brakes.

I bench bled the mc
And my owners manual said closest to farthest
Which made NO SENSE
But I tried it and tried it
So I did as I've always heard
Farthest to closest
And sure enough
It worked
Thanks for all the help y'all
