1956 Thunderbird power brake problem

[miker98038]

They used to “arc” the shoes to fit the drums. Pretty hard to find anyone who still has that equipped today. But if they aren’t done then your initial adjustment is a small point of contact. It’ll wear off in 100 miles, so it needs another adjustment. It gets more complicated when you turn the drums, etc. But you might ask around, where you are people are less inclined to throw things away. If I’m telling so something you already know, my apologies.

I’d tighten them back up, see what happens. There’s a link here somewhere on the parts to buy to retrofit 57 self adjusters to the rear drums. That really helps.
