Rotors Cadmium or Zinc?

[Tein]

What would be better for corrosion: Cadmium plating or Zinc plating? And do the Gold plating color last?

Rotors? As in brake rotors?

You mean calipers? You can't plate rotors.. Well.. some show only trailer queens have chrome plated rotors, but not on any street vehicle.

Brembo use Zinc plating and Powerslot used Cadmium plating to protect their rotors from corrosion.. and every manufacture used one of those too....

Odd. I suppose it makes some sense.

Quoted from brembo:

Cadmium plating confers rust resistance. (Any plating wears off the braking surface, of course.)

Brembo brakes are the best!
Umm, I have an idea, just get some solid 24kt gold rotors so that it wont rust, and every once in a while, have the jewelers clean that thing =D

There might be a small issue of the rotors melting though.

my brembo rotors rusted up quick

must be all of that heating and cooling i do

The plating is only there to protect the non-contact area of the brake. And from my experience, neither plating works very well long term. The plating tends to burn off over time as the brakes heat up and cool down. I would recommend Brembo over the other one.
