Aftermarket part.
Register to hide this ad
The owner of the car had no idea. Except he heard a big CLANG and scraping noise. I think his mechanic used one of those online parts places that may have had counterfeit stock.
Most likely Chinese (or some other offshore) counterfeit. Unfortunately, a lot of that today.
The saying is that those ppl spend more money making the boxes look legit, than on the part.

Stuck caliper?
He said the pads actually had popped out of the calipers. That's the CLANG he thinks he first heard. The calipers were damaged beyond repair.
He hasn't replied to me about how the other rotors looked.
I asked him if the brakes showed signs of overheating. Or if he had used them excessively (racing or long downhill runs).
He told me that this happened just after starting off in the morning. Of course, the metal fatigue could have started long before the failure. Like during manufacturing.

Maybe, or not.
Everybody always blames the parts and/or the manufacturer but a broken part doesn't inherently mean it's a part quality issue from a materials or manufacturing standpoint. Correlation vs causation.
Ever watched those "Customer states..." YouTube videos?
Personally, it looks to me like the pads for that brake may have been gone some time ago, and he didn't notice the grinding until the big clank. Looks like lots of crazing too, often a sign of overheating.

Your friend has been driving with no pads on those rotors for a long time IDK how could he not hear the metal on metal grind/squeal. That rotor suffered from massive overheating, hence the crack in the outer part of the rotor where that pad runs. The crack in the hat portion likely happened when they tried to get that rusted piece of junk off the car.
Check out the rotors I removed off my wife's 2016 Charger compared to the Chinese "Power Stop" ones on my 2016 Charger... sometimes factory parts are inferior. Apparently most brake rotors made today start off as cast blanks in China (they make two grades, cheap schiit and good schiit). The cheap AutoZone types are machined there in China (and they stink on ice) the fancy ones like mine are machined in the U.S. :

Brake Rotors - Metallurgy and Composition
When it comes to vehicle safety and performance, your braking system is one of the most critical components. It can be a little tricky to find cost-effective, high-quality performance rotor options on the market, especially with big name brand products that overuse buzz words like “performance”...

Brake Rotor Material Differences
Different Types of Brake Rotors Brake rotors (aka brake discs) are an essential part of your vehicle’s brake system and are the friction surface that the brake pads squeeze to slow down the wheel’s rotation. Compared to a bicycle; a bicycle rim serves the same function as a brake rotor/disc...

I do that at least once a week because I like to admire my brakes: I installed the huge 14.5" Front, 13.8" rear Police Pursuit brakes on my Charger because I tend to go fast and stop hard. Comparison picks between the stock brakes that come on the V-6 and the Police package:
I did a brake upgrade on my Towncar, but it was from a 10.5" rotor to a 12.2". Not particularly large by modern standards but absolutely massive improvement in braking performance. It got larger pads and dual piston calipers with a fair bit larger total surface area to go along with it. Same rotors that I put on almost 20 years ago now. They weren't anything special, just whatever Pep Boys was selling back then but they are US-made.
