Allignment or braking issue?

[zehnderm]

I've got a 65 coupe that pulls slightly to the left when braking. They're stock drums that have recently been rebuilt. Is it possibly an issue with one of the brakes grabbing early or an allignment issue? If its a braking adjustment issue, I heard that drums are self adjusting and can be "adjusted" by braking while in reverse. Is that correct? Any help would be appreciated.

the problem with stock drum brakes is that the pressure in the system under initial braking is unequal, and biased to the left front corner due to the shorter line run.

It sounds like the pistons on the right side may be hung up causing the brakes on the left side to catch first. When a car pulls the problem is usually on the opposite side from the pull. I doubt it is alignment if it only occurs when braking.
