To some extent, there may be some slightly higher quality control of a
certain brand that might have a reputation to maintain. My family
mechanic explained the whole story of when all rotor manufacturing
went to China. He used to work for a US company that made them until
they shut down. He's been a professional mechanic for over 30 years
and has seen the quality of rotors go down firsthand. Same for a lot
of brake pads he tells me.
Well - he only tells you what he wants to see. I don't care if you believe
him or believe the evidence that contradicts his stories. Like I said,
there is some pure junk out there and there is some very high quality stuff.
Believe it or not.
Seeing as how rotors are probably the MOST important part of a car's
features with respect to safety, it HAS to meet a certain standard of
quality for the US even if it is made in China. If there were rotors
coming out of China with high failure rates or were lasting a year,
people would be filing class action lawsuits or vendors would stop
carrying them. Manufacturing spec and grades aside, it's splitting
hairs as far as I see it.
There are indeed rotors and pads coming out of China that only last a year.
And - there are no class action suits as you claim there would be. As well,
while rotors were being manufactured here, there was junk out there. Rotors
that only lasted a year, etc. I'm no big fan of our manufacturing moving
off shore, but if you believe that the American manufacturers did not
produce their fair share of junk, you're mistaken.
Look around your life. What do you consider to be a quality item? Where is
it manufactured? There's a good chance - almost a guarantee that some of
the things you consider to be quality items came here from China. You just
can't make those broad brush statements like your mechanic does. They sound
good over a couple of beers, but they just don't hold water.
