2010 Silverado new front rotors and pads.

[Snagglefoot]

My son’s son’s Silverado was making some low speed braking noise after 5 years and 50,000 miles after last doing them. The pads were only 1/3 worn but the inside edge of the rotor was disintegrating and a good rust edge was developing. There are small grooves in the rotors.

We went with Canadian tire OE plus rotors as before but this time used OE Plus Pro ceramic pads. Pretty fancy name for pads made in India.

So basically the last set of OE Plus pads were only 1/3 worn at 50,000 miles but I think the rust particles off the OE Plus rotors might have been causing groves. The old rotors had a black coating but it was gone after 5 years. Here are some pics. Enjoy.

They actually look really good after 5 years and 50k miles.

What's the rotor on top, it has a black hat and x-hatching, but the one on the vehicle does not...the rusty rotor has huge lips, even with thick pads likely affects stopping imho, can see the impression on the top pad where it's cutting the pad

It’s a strange optical illusion. The hat is actually grey and the paintless crosshatching is the correct look. Another shot almost makes entire rotor look grey, but no, only the hat is painted.

Are those cracks showing up on the inside surface of the rotor?

More of an etching than a crack. Also it can’t catch a finger nail dragged across it.

Yes, and it’s probably what was causing the noise.

I’m northern Ohio and obviously not Canada, I still get the state dumping salt on the roads like they’re trying to get rid of it at the slightest snowflake. I bought a can of silver Por 15 and am going to paint the hat and vanes every spring, just to see if it helps. I usually change rotors and pads every few years because no geomet/rustproofing ever holds up. And I can’t stand unsightly open wheels.

I only use fully coated rotors. It does help. Salt is murder on disc brake rotors. Even when parked any moisture trapped under pads is eating away at them. Not to mention brake parts do not get fully heated up and dried out driving in snow/ice. Getting 40k miles out of them seems to be the norm on my fleet.
Only good thing I can say about drum brakes, they were more salt resistant.

I miss the days of closed wheels and hubcaps lol. You never knew what you were in for!
