Rebuild K/H Calipers Versus Remanufactured???

I can purchase "remanufactured" Kelsey Hayes calipers for $100-$150 a pair (depending upon the source).

Or... ... ... I can purchase a hone, rubber kits, and 8 new pistons for about the same money, and do it myself.

Who rebuilt those calipers? Did they use "NEW" pistons? Made of aluminum, steel, or made of what?

Which is a better way to go? Why? Thank you FABO community.

I don't know if you can still get them but years ago I got rebuilt original calipers from stainless steel brake in New York. They stainless steel plated the body, put stainless steel pistons in, stainless steel retainer clips and a stainless steel tube connectiong the two sides. I haven't had to touch them in 30 -35 years accept for flushing and replacing pads. Back then they would either exchange for ones in stock or redo yours. One of the best things I ever did for the GTS Dart.
