Hey folks,
I'm getting ready to take my '13 FR-S to a track for the first time so I was doing some checks/inspections when I noticed the inside of my caliper pistons were completely rusted. (Photos attached) She was originally titled in CT so the rust isn't surprising, the amount of rust is what's concerning me.
Steel/brass brushes proved useless, and I'm worried this may not hold up on the track. I gently peeled back the rubber gasket and I saw that the outside of the pistons are relatively clean save for a few specks of rust.
I've got track pads and high temp fluid on the way, should I add calipers to my shopping list? If so, are the remanufactured ones on rockauto good? My heart wants to get new/reman'd calipers for peace of mind but that'd mean track day has to get postponed again
Thanks folks, happy to answer any other questions.
