On a ride today and suddenly lost braking pressure, looked down and saw on one of the pads the breaking surface had come away from the pad.
I thought I'd get to the next aid stop using the rear brake but on the next hill very very quickly got brake fade before complete brake failure, and again it looks like the breaking surface has stripped away from the pad. All 4 pads has been replaced around Christmas time and you can see decent thickness on the one remaining pad.
How is this even possible? Did I buy fake Shimano pads? (Bought from eBay but nothing in packaging or appearance to suggest a fake)

What compound? Those organic? The sintered pads last longer and resist mud and wet better. Also might have gotten a defect.
The surface of the metal doesn’t look like shimano brake pads. 100% certain those are terrible fakes. It looks like they attached the pad with white glue.
If you want genuine parts, buy them from an authorized retailer.
Fake stuff is so easy to make now, and packaging is easy to copy accurately. The only way yo know what you’re getting is to buy from a retailer that is supplied directly from shimano.
The coating on the backing plates looks off and the way the pads are bonded looks like they just used regular glue so these are likely fakes.
This is why I don’t buy components off eBay and Amazon.
That rougher texture is something I’ve seen on other L05A pads, a lot rougher than my J05As.
The current “ice tech” pads with radiators are glued, while the steel-backed ones have rivets. I suspect you simply overheated your pads and caused a glue failure.
Most chains and pads from Amazon or eBay are counterfeit. Lots and lots of other counterfeit parts that would surprise you.
Even a legit seller on Amazon isn’t safe because inventory is co-mingled between sellers.
Just never buy bike stuff from those sites, not worth the risk.
I buy mine from a genuine reseller and I still think they are worse than they used to be.
How much did they cost?
[shimano has issued a notice about this exact thing happening on fake pads alongside a guide for identifying fake B01S pads](https://bike.shimano.com/en-NA/stories/article/information-for-the-counterfeit-products-of-our-disc-brake-pad.html)
Real friction
dude i use some cheap aliepxress brake pads for years. why use these?
Support your LBS, you won’t get fake shit and be supporting a small business. Can’t fathom buying from EBay/Amazon/AliExpress etc etc
Ebay/Amazon etc are famously full of fakes…. Reddit is full of people warning not to buy from either of them because you are more likely to get fakes than genuine items, Hell even the wider Internet is full of warnings of fakes on there.
You just found out what happens when you choose not to buy from a trusted source.
Every bike product not sold by a trusted retailer is fake. I will never buy anything but cleaning products from elsewhere.
