Looking to replace my rear calipers on my Gen2. I did the rear brakes, new rotors and new pads, but I had a problem when them dragging, likely due to corrosion behind the pistons. I took them back apart, lubed everything up again and it seemed to fix the problem, however for peace of mind I am just going to replace them.
I looked on Rockauto,and while the prices were good, the return of the cores look like it is on me and shipping made it cost more too.
Checked locally at O'Reilly's and they carry ones with the Phenolic and Metal pistons.

I will probably go with these from Amazon. No cores to worry about, and since I am a prime member I get free 2 day shipping. They are Raybestos reman calipers. I may tear down the stock ones I have and rebuild them for next time. (rebuild kit is like 5 bucks a caliper). No description on Amazon, but the same parts on Rockauto say they include New Phenolic pistons.

Anyways, what are the pros/cons of each kind? I am not sure what kind come new on the Trac. Only info online I could find said that the metal pistons are more prone to corrosion and sticking. But I saw people saying the Phenolic don't transfer heat into the fluid as easily but they are more prone to cracking. I would think that replacing the calipers each job would help out with the cracking.
Does it matter what is on the Trac now, or are the interchangeable?
Looking at the rear pads, it seems there are only one type available, so phenolic/metal must be interchangeable.
