Well, I do have some good news in regards to Dodge ram brake shoes. I found an article on the internet pertaining to 1994-2001 Rams, which has the following quote:
"Brakes were designed for best in class feel, stopping ability, heat resistance, and durability, with standard sliding caliper front disc brakes and dual servo rear brakes on all models. Front brakes used slider single piston calipers; the sliders protected against contamination and corrosion. Rotors, drums, and power brake boosters were larger and (except for the booster) thicker than on the previous generation. A quick take-up booster and master cylinder assembly, similar to one first introduced on the Viper sports car, responded immediately to pedal movement. The systems were self-adjusting; and lining materials had no
asbestos. Steering knuckles on 2WD models had integral brake caliper anchors for simplicity and low weight."
Here is the link, scroll down to, "Steering, wheels, tires, and brakes":

So, apparently we don't have to worry about asbestos when working on our OEM brakes, that's good news.
