Have had problem after problems with these…firstly they’re not 1.5 mm. Butt the biggest problem is they’re not flat, 2 out of 4 that I bought were raised at the edges making it almost impossible to line up. They. Are quiet but worked 2 hrs trying to set. I even filed down edges… Have now fitted original srams back on..

Bought to replace some stock SRAM pads, they turned out to have good stopping power, but sound like a fog horn. I installed them while wearing gloves, onto brand new rotors, made sure they were straight, and then bedded them in as per Swissstop's own recommended method - and they are so loud they'd wake the whole street up. It's actually ridiculous. I've swapped back to the stock SRAM pads for now. Also, on one set of these pads, the included hex bolt stripped. I had to use some plyers to remove it and have instead also used the stock SRAM screw. This resulted in some nice scratches on my brand new callipers. Overall, would never buy again.
