1966 coronet 440 rear and front brake question

[Sewalsn20]

Hey guys, just finished up the rear brakes on the 66 coronet i got recently that i posted about and i have some questions about the front brakes. it's 10" drums all the way around. the front brakes are gutted so ive got no reference. the shoes front and back are interchangeable, but was wondering if the upper springs, self adjuster cable, adjuster bracket, star adjuster and guide for the cable are the same too as the back. i got the master brake kit for the car but the shoes i got require the long yellow spring on both shoes per wheel and the kit i got gave me one yellow upper spring per wheel. if all the parts are the same i'll be able to get them from the parts store tomorrow and get the front done too on my last day off! i'm going to post a pic here of what i think my fronts should look like, they look very similar to my rears. TIA.

As far as I know self adjusting brakes were not available in 66. However you can update them to self adjusting and they should take the same hardware front to rear.

The pictures are correct. One long spring, one short spring on top. Self adjusters were used in 66.

I posted a question within my Dot 5 fluid post but did not get an answer. It would be similar to this post. It's a 66 Charger and does have the self adjusters. And 10 inch brakes. The springs on top are one yellow and one red or near red. One was slightly (1/4 inch) longer than the other but which way do they install? Yellow on the left or right? The reach looked the same. MrDee previously posted a color picture of the brakes/springs installed and the passenger rear had the yellow spring on the right. When I took mine off the yellow was on the left. The self adjuster cable side. Anyone know the difference and the reason for two different springs? Manual does not say anything I could find.

My 64 Plymouth Sport Fury I bought in 68 had self adjusting brakes. They caused me some problems with the rear brakes.

Today I replaced the left rear wheel cylinder which was frozen inside just like the pass rear. That might be why I was having issues with the self adjusters. Before one began leaking the adjusters kept getting tighter. But w/o the pistons moving in the cylinders that might have been the issue. Lot of crud in the cylinder too but with it having Dot 5 fluid they did not have a lot of corrosion inside the cylinders. Still, they locked up. Time will tell but I have backed off those adjusters three times in the last month due to the brakes overheating. If it happens again they are coming off. Also went on line for a deeper search into the color of the springs and what I found is that the yellow on the rear goes to the shoe with the e-brake. Secondary I think it's called which is counterintuitive since it does more work.

Now I have to move to the front which look like they have been serviced more recently but I don't trust any previous work done on the car now. And the drum brakes continue to improve.

One thing that gets overlooked is the adjusting sequence. The emergency brake needs to be fully backed off so the shoes seat properly on the upper anchor points. Then the service brake gets adjusted. Then the emergency brake gets adjusted. Out of proper adjustment can result in brake drag.
