Why Coated Rotors Make A Big Difference

NAPA Brakes Ultra Premium 100% Polymer Coated Rotors

Couldn't pay attention to the video. Was rocking out to the music 🤣🤣🤣

Looks to me like the issue is with the caliper, which wasn't properly cleaned and lubricated when the pads were changed, which prevented proper operation of the caliper and full pad contact on the inside surface of the old rotor. The benefit of the coated rotor is that it prevents corrosion between the hub and the rotor and will make it easier to remove the coated rotor from the hub at replacement time.

Why the music?
It's quite disturbing.
I want to hear the man what he's saying not the music...

Good video. Lower the music volume or get rid of it though

The main reason I use coated discs is that they stay looking nicer for longer. I have never had an issue with corrosion creeping across the brake surface with any discs or pads.

Shows a used "uncoated" rotor. I think there would be more value in showing the difference showing a coated rotor after the same amount of wear.

Music sound track nothing but an annoying distraction when trying to listen and learn. When will people stop this society of continuous useless noise?

All new rotors are nice and shiny. Would like to see what that coated rotor looks like after a few years.

I have these, I live in Ohio. initially, they do look better for a longer time. They do still rust but it takes a year to a year and a half before it’s noticeable.
after three years they’re basically totally rusted and need replaced.
Worth the extra $10-$20 per rotor. IMO

Agree that the wear on the back is caused by a seized caliper. I had this exact problem on a couple cars. New calipers, rotors and pads fixed it. The NAPA calipers are great.

[abymondesir]

Always wondered abt that coating but yup straight to the point and makes sense

[johndelk]

Rotors are designed knowing they will rust, they do not lose performance. The guy even shows us the uneven wear was caused by the caliper.

Just aesthetic benefit. Who's ever had a brake rotor/disc rust out before being worn out. There is rust on the inside of the disc in the vid because the slider pin was seized causing the pad to not fully contact the disc.

In NY state they salt the roads so much in the winter that uncoated rotors look like that after 2 years. Coated ones will last longer - but the rust still creeps in under the edges of the pads. They might make it to 5 to 7 years.

Good product, used them to replace the worn out (22K) rotors on my 13 Ram. Very reasonable cost for the quality. Especially compared to OEM and the coating is holding up nicely.

PS: please lose the goofy fake metal music in the background.

A very informative video. Thanks for producing it.
Has anyone noticed a reduction in braking power after going through a car wash? Even after my brakes are dry, even days, weeks or months later it seems like there is a reduction in stopping power. I’m assuming that it is due to the waxes used getting absorbed into the pads. Anyone have any thoughts or answers? Thanks...

I have Sachs coated discs on my car and before that, Zimmermann coated discs. They look good for a while and after a winter looks all rusty. I see no silver color anywhere after 4 years. Just as bad as my non-coated Brembo discs looked like.

[pvcarmon]

I put sets of four on two different cars and almost a year later, I confirmed the polymer has come off on sections of the hub appearing burned off. Can't confirm how the rotor veins look but I would seek another coating option. Great in theory but this "polymer" does not seem to hold up well not sure if it is worth the expence.

How about dropping that rotor on your foot?
It will make for a more interesting video plus you can test your safety shoes.

purchased these rotors and replace stock rotors after 6yrs @100k miles from my 2014 chevy silverado. so far no issues !!!
