HELP - ZERO BRAKES

[440R/TCharger]

I have a 66 Coronet 273ci with power brakes. I had no brakes and I have replaced all of my drum brakes, the power brake booster, and the master cylinder, bled them all the way around and yet I still have zero brakes. Any help much appreciated. I am still using the original distribution block as it is the original style master cylinder.

vacuum loss/ leak? A dual master cylinder would be a nice safety upgrade I think.

I'm betting it's your MC.....

Booster leak or vacuum leak still will allow a pedal. Distribution valve failure will still allow pedal. This problem is most likely a problem with air or to much travel of the shoes.

Could be or he did not properly bench bleed the master.

I've never bench bled an MC in my life lol....

If there is air in the master cylinder or in the lines it would show the same air bubbles upon bleeding. He says he bled the brakes.

Said and thought he said are common responses. Fact is he has something very simple wrong. Its not rocket science. Its a simple hydraulic system.

Whoa....TWO posts in 15 years and one of them is today!
The term "No brakes" is vague and needs to be elaborated a bit.
Are you claiming a free travel of the pedal with zero resistance to the pedal?
Is it that the pedal does have resistance but still goes to the floor? Does the pedal get a little firmer as you get to the floor?
Are the brake shoes adjusted out to where the drums have a little drag to them while spinning?
Is the linkage actually attached under the dash?
Did you get fluid flow when you bled the brakes?
Were there any bubbles?
I know that some tasks we do can be frustrating. We all have been there.
To help you, we would need more information. You can't just expect the members to play detective while you keep all the clues to yourself.

if he bled the brakes properly; either his adjustments are way out, or he has a massive leak under pressure
