I tried using small hills. Braking for less than 10s. Even sanding off the top layer as a last ditch. I've ordered some cheapos again now.

I've tried shimano oem pads, cheaper ebike blue pads from ebay, these are the only pad you will ever need. So consistent and dependantly powerful. Last ages too. You won't regret them.

Looks to be plenty of ‘meat’ on these pads. Comes with all the parts to fit them - easy process. They’re just fitted new so time will tell if they were a reliable disc pad.

These are the best brake pads I've ever had, I actually had to get used to how good they were as the bite is so on point. I'll never buy cheapo ones again. They do sing a little bit in the wet, but still a great bite.
