are all rotors made in China?

just for info, I ordered Wagner rotors thinking I was probably getting made in USA. The box the rotors came in shows, "Wagner Brake Products, Federal Mogul, Southfield MI, distributed Federal Mogul Canada, Concord Ontario. Bar code shows "Made In China".
Just curious, are any rotors definitely known to be made in USA? I've seen internet info saying Wagner were either USA or Canada, but the ones I purchased were China.

A quick search turned up that for my van anyway, Allied Signal makes theirs in the USA.

Thanks, I will look at Allied Signal the next time I check into purchasing rotors. I noticed you have a 26' Jayco and 2 vans. I also have a 26 ' jayco which I used to pull with an e150, 5.0L. The 5.0 didn't like the combo of the mountains plus the trailer. The van cut off several times when it began to get hot. I flushed system and added oil cooler, but didnt help. I dont use the van for towing the trailer anymore.

Ya. That's quite a load for a 5.0. The 7.5 was nicely sized for my motorhome but the mileage killed me.

My Motorcraft replacements were made in China, drums and rotors.

While some of the oem installed are made in the US, almost 100% of the aftermarket comes from 1 of 2 foundaries in China (even Allied). many will state their rotors are mfg here, what they are actually stating (legally) is the rotors are casted in China (even brembo with the exception of their high end rotors) and brought to the usa where they are machined.

There are 4 grades of rotors- it is best to look for a supplier who only uses the top grade units- even with those, about 10-15% are sold off to major chains while the remaining stock requires machining. I also highly recommened cryogenically treating the rotors (about $15 each) because this corrects (so to speak) metaluric deficiencies that are not detectable by magnafluxing, etc but can show up later in the sign of warping, etc.
