2000 Astro Brake Suggestion And Question

Hello
I have a 2000 AWD 6cyl astro. I need to replace front rotors and brakes
I tow a boat also. I thought I was told once this vehicle takes a special pads on front and now when I call parts stores I get conflicting info
The weight of vehicle plus towing

ceramic? parts store said not if towing
or
semi metalic ?

also if I have all aluminum rotors or 2 part composite. I was told to hit with hammer and if different sound that would mean composite. The problem I wanted to get all the parts so I can do the job this Saturday and time is critical so can anybody guide me in the right direction.
Also when it comes to brakes i don't mind spending the money if it is justified so if the best is what i need feel free to suggest. I really enjoy this site and have been helped as well as lending info. Thanks to all

The vehicle originally came equipped with composite rotors and semi metallic pads. The braking surface of the rotor is cast iron with a thin composite material used where it fits over the hub assembly. Composite rotors were used to reduce weight, durability was sacrificed as a result. They are interchangable however, when replacing rotors, it's best to use the same type on each side. A good quality, brand name, (Bendix, Wagner, Raybestos) ceramic pad will do fine. Make sure the rear brakes are working properly and that they are adjusted properly.

Personally, I'd install carbon metallic pads. They make a little more noise, and produce a bit more dusting, but flat outperform any other friction material. They really shine once they get warm, which is likely to happen while towing.

I don't tow but i do occaisionally carry 1000 pound plus loads. I second the opinion for carbon metallic. I've put Autozone's Performance Friction pads on the front of my 2000 AWD and have got some crazy mileages out of em (like 70,000 plus), AND they're lifetime warrantied!
