It's a shame that no one has the incentive to do a expensive scientific controlled brake pad test against oem.
Why because HISTORICALLY aftermarkets regardless of the price FAIL sometimes miserably in street driving in dry and wet as long as the tests are done under 120 mph or are limited to 4 - 60 mph or 3 - 80 mph back to back tests.
Brake pads are so universal because the entry cost is low because you can buy premade backing plates in standard shapes and sizes. {there are Chinese Comapanies that just specialize in producing backing plates at a very low cost ---- including freight they are less expensive than they can be manufactured in Japan, US, or EU or MEXICO.
The material cost to formulate a pad compound is low, not only that but brake pad companies will custom produce your formula CHEAP and let you rebrand theirs.
I get ill sometimes looking at the number of compounds in the world and no real way to find PUBLIC info for comparison.
Take some time to download this 202 page pdf test done in 2000 on the various brake pads available for 3 different police cars and you will see the problem and understand the scope. Very interesting and educational to all.
