Re: Why is drum to disc called an upgrade?

Here'a a non-BS anecdote, but it was from my 69 B-Body, not my truck. It was four wheel drum and eventually became four wheel Wilwood disc.

Best stop I ever made in all drum was a dog ran out in front of me on a highway. I flatspotted tires and wound up sideways but stopped.

By comparison, 20 years later and same car with discs, the throttle stock open and I had to pile on the brakes. Not only did it bring the car down in speed as turned the key off, they allowed me to completely stop straight and true in my lane with the steering column locked (turned the key one step too far back in my panic!).

So I've lived with the same car both with and without, and while I limit my enthusiasm to stock GM setup, I really do prefer the disc.

Keep the speeds down (like WAY down in town) and drums are OK.
