Replaced the rear shoes on my 70 yesterday and when we went to adjust them we noticed the adjusting opening (slot)was on the brake drum and done from the front. My recollection when we (my brotherinlaw and me)did my 67 (all 4 drums)a few years ago this slot was on the backing plate. We put the tire on and spun it whilst we did the adjusting. This obviously cannot be done with the slot on the drum and adjusting from the front. Is this correct?? And what is the best way to do the adusting now?? Get it close and drive it in reverse and hammer on the brakes a few times and let the self adjusters do the work???

BTW...I am pretty much a rookie at doing (shoe) brakes but every time I look at all the pieces parts that go into that design, I have a hard time imagining somebody actually sitting down and designing this years ago and bringing it to their boss
and getting it approved. With the correct brake tools, it turned out to be a 5 scrape/cut job to do 2 brakes. If I would have had to do all 4 by myself I might have needed a transfusion

Robert,

My 70 is the same way. My drums were original and un cut when I did my brakes, the knock out plug was never removed. Being I did not want to remove it I adjusted the brakes by expanding the star wheel adjuster a little at a time. Each time I would replace the drum until it fit just snug with a slight drag on it when spun - with the tire off. You have to get a good feel for it.

Don't make it too tight as it can heat things up and liquify your brake fluid.

Hope this helps.
