tires and brakes on my four winds chevy 3500 chassis

Did much more research and actually the industry states that semi-metalic pads are far better for heavy vehicles than ceramic and they stop better in high heat. That is why most kits containing a rotor and pads use these. That is what I am going with and heavy inspection of the calibers....I have had sticking calibers before on other vehicles along with bad and worn guides. Thanks Will look at the link Rolin sends.
