'63 brake bleed question

[whateverpratt]

I just replaced my master cylinder since it was the culprit of a long time leak that became a lot more prominent over the last week. I bled it before install, and now I need to bleed my wheel cylinders so I don't have to pump the brakes to make them feel like they will stop the truck.

I am wondering about the bleed sequence I should use. The truck has manual brakes and drums all the way around. I have the shop manual, and it says left rear, right rear, left front, right front. My brother said he bleeds his malibu left front, right front, right rear, left rear per his shop manual (also manual brakes drums all the way around).

My question is, is there a correct way, and if there is, why is it correct? Does it matter what order I do this in?

It seems like a silly question to me, but I've had different people tell me different sequences and ways to bleed the brakes. I was just wondering if anyone had some valuable insight.
