I need new brakes for both of our cars. Where we live with winter salt, the failure mode for brakes on our cars has always been the rotors rusting on the inside, and creeping onto the friction surface wearing grooves into the pads causing noise. My Camry is only 4 years old and this just starting occurring with the factory rotors. On my wife's RAV4, I used Raybestos e-coated rotors and they are rotted up after only 3 years. Generally I get 4-5 years out of factory rotors, and only 3 out of aftermarket even with the e-coated vanes and hats. It sucks because the pads have lots of life left when this happens.
I don't want e-coated rotors. The hats and vanes are coated, but not inside the hat. The failure of all of my rotors in the last 10 years has been rust creeping from inside the hat onto the braking surface. The new "coated" rotors with the silvery coating seems to cover everything, even the inside areas that cause the problems. There are a few options so I wanted to see what the opinions are.
Raybestos has the Element3 line with the RPT coating technology. They say it holds up under 300 hours of salt spray testing, and they are pretty cheap. What I don't like is that it says the maximum lateral runout is 0.004", which is crazy. The factory specs are maximum runout of 0.002" so I don't know how a brand new rotor is so sloppy.
NAPA Ultra Premium coated rotors are quite bit more pricey, and I've heard they are repackaged Raybestos rotors. They say their coating is polymer, and the maximum runout is 0.002" so it would appear they are different from the Element3. I like that they have a lifetime warranty, so I assume if/when they rot out I'll get new ones for free.
A lot of people like the coated Powerstops, but I can't find information on runout, and the warranty is lousy.
Are any of these any good? Are there other options that you've had good luck with? Again, I want something coated, even inside the hats, so that eliminates all of the black e-coated ones as far as I can tell.
