I'm unclear about 'organic' (NAO) vs ceramic vs semi-metallic.
For years, I'd just go to the parts store and say "I need pads for [whatever low-end Chevy I was driving]," and then get the 2nd-cheapest pads. AFAIK, they were always semi-metallic.
... the majority (roughly 70%) of new cars sold in the US still come with [NAO pads] from the factory.
... [NAO pads are] Suitable for normal driving/commuting across many environments
And other things like this:
Ceramic brake pads are generally a term for a group of pads known as NAO or non asbestos organic pads
If you have a high-performance sport car, or at least drive your vehicle like it is one, you're likely best off choosing semi-metallic brake pads. On the other hand, if you do a lot of urban commuting, you might find a solid ceramic brake pad to be the better option. If you don't put a lot of mileage on your vehicle, an organic brake pad might be the best, low-price option
So, my question(s)
- Does "ceramic" really mean NAO, ex when they cost more than $xxx?
- If not, are NAO pads available? How are they identified?
- Were the pads I bought back in the day really 'semi-metallic', or were they probably actually NAO?
