When I did it to my '71 Plymouth it was a bit better, but not a lot. But then the car was only about 3 years old. I also changed it from manual to power brakes. And from the little rear end with the little brakes, to an 8 3/4 from a station wagon and 3" shoes. Also it doesn't make any difference what year it is, it's still better.

I did a conversion on my 71 Road Runner with all factory parts, and everything just bolted on like it was, well, factory. I can tell a big difference in fade resistance. RRs had 11 inch heavy duty drums which are powerful, but one good hard stop, and that's it. That was my biggest issue, brake fade! I learned to push, letoff, push, let off with drums on my Cuda. I spent a little more money and did the aluminum hub and aluminum caliper Wilwood Pro Street kit on my '63 Dodge. Vented (but not drilled) rotors. The car stops from 121mph runs in the 1/4 mile easily and consistently. It was a very easy kit to install on my existing drum brake spindles and took a LOT of weight off the car!

A previous thread on here pointed to rubber lines bulging, might want to make sure those are solid. Any ideas on life expectancy of the hoses?? Mine are appx 11 years old w/ 6K miles on them...

I used all Mopar parts on my '64 Polara. Spindles and caliper mounts from a 76 Dart. Master cylinder and calipers from a '75 Dart and rotors from a 77 Monaco. Everything just bolts together. Lines were from a '75 dart and just needed a little adjusting to clear and work perfectly. Spindles were swapped side to side so the calipers could be moved to the rear so they would clear the factory sway bar. Without a sway bar they arr mounted on the front side. No tweaks needed for the brake lines if they're mounted in the stock location. The Monaco rotors are one piece 11.75" and are much stronger than the "A" body rotors.

If you use A body calipers, ask for ones for a '76 A body as they have a 2.75" bore as opposed to the 2.60" for '73-'75 A calipers for more front bias. external dimentions/fitment is identical. & you might measure the bore at your parts house to confirm you are being given the right ones.

I swapped 11.75" discs on my 64 300, replacing the 11x3" drums. The drums would pull in different directions when they got really wet, other than fixing that nothing was a lot different. Didn't do enough stop and go traffic to get the brakes hot enough to fade and I drove that car with drums for over 5 years in San Diego, took it to Memphis and back that way as well. So I really got to wonder about the real cause of brake fade.

So I really got to wonder about the real cause of brake fade. I wouldn't even call it fade, just doesn't have very good brakes.. I want to think they were better when I first got the car back on the road, so maybe some maintenance needed on the brakes....

I wouldn't hesitate one second to change to discs, if better braking was desired (fronts), and if for no other reason that has yet to be mentioned, much better driving/braking in the wet. I believe drums can be, when in a perfect setup pretty close to discs, in limtred stopping situations, but they seldom are in perfect balance/tune/heat/etc, and in every other hard barking situation, they become limited, just by design.
Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

My 64 300 did not have self adjusters in the front, so you needed to manually adjust them, I did every oil change. Quality shoes help too. New hardware and a flush.
