Doing brakes on a 72 Dart. Any upgrades or pad advice?

I generally agree. I'll quibble on what type of material stops a car 'better'. Because in general I do agree that 'semi-metallics' tend to be a good choice for these cars and
my only quibble is that's gross simplification.

Oh of course, there are a lot of different pad compounds and manufacturers out there and how well they work on a specific car depends a lot on the use of the vehicle. There are pads for race use that will stop the car amazingly well when they’re hot, but don’t work well at all cold, so despite their race pedigree they’re a terrible choice for a street car. But on the street the general category of “semi-metallic” pads work quite well.

Saying the factory pads work better than what’s available in the aftermarket now is complete folly. Not only is the asbestos dangerous to your health, there are far better options available.

The member posting about his NOS pads pretty much just spams brake threads trying to sell his stuff. Other than arguing with me about the false claims he’s making about the performance of the original pads, pretty much all of his posts are an attempt to sell his parts. Honestly he should probably be required to have vendor status the way he posts, but that’s just my opinion.
