Does' the 2004 Trac rear calipers, have steel or phenolic pistons.?
Eddie, factory 2004-05 have phenolic rear caliper pistons. IIRC, earlier build 2003 ST's used the larger bore steel pistons.
Shoot, I was hoping for steel. Maybe they are better now, IDK. My past with older cars and phenolic's, wernt' good at all. They distorted from heat, and cause siezing. When I rebuilt my own calipers, long ago. I replaced them with SS or chrome plated steel.
I wonder what rebuilt calipers use.?
Rebuilts use both steel and phenolic. Thought I read Todd Z converting to steel piston calipers. Don't remember front, rear, or both.
Thanks Steve, For some reason I just now found your reply...
you can change them, look on rockauto and just buy the calipers you want. They used to offer them both..
My 03 came steel but I went plastic due to it sitting a lot to prevent rust..... Different pad Number too...
