I'm getting ready to replace my calipers on my GX470 (think 2003-09 4runner).

There is a well known issue of brake caliper pistons corrode and bind within the caliper cylinder.

Wondering if I could cerkote the pistons and/or the caliper bore before they go in to prevent corroding issues. Thoughts on if this would work or any issues this would cause?

Just flush the brake fluid more often. If the dust seals on the calipers are in good shape and the fluid is fresh (less than 30 months old) you shouldn't have rusted pistons / rusted caliper bores causing binding.

Get coated calipers if you can. Cardone Ultra or Napa Eclipse smile
