It appears OE stuck with the phenolic piston. I am not having issues with that, just the thing rusting out. So I am looking at ~ $42 a caliper.
As for the rotors, I am trying to decide either the USA made OE replacement @ 62 dollars each, or the performance drilled and slotted at 124 a piece. I hate replacing my rotors. This will be the 2nd set of replacements in 3 years.
One thing though that is bothering me, is that I have a 95 F150 built in Kansas on 9/04. It seems that there were changes to the hub assembly for the 95 year trucks depending on the build date (before or after 5/95). So, I am going to look into what the deal is. The only thing I notice is that I do not have a pin that slides through the caliper (caliper sliding pin).
