I recently replaced my rear brake pads with normal ones that made no anti-squeal claims: lovely, no squeal, no squeak, and the braking was amazing. I then decided to replace the front ones, and I thought I'd buy these, to see how they were, particularly because our other bike has a problem with squeaking, and it meant I could test them as an option for that one.
They squeak, they squeal, really badly! My rear brake is still squeak-free with the other pads, but my front brake with these "Anti-Squeal" pads is making a loud squeak/squeal noise every time I brake!
It seems that others have had good experience with them, so perhaps they work for some. Don't discount their experience, but for me, they've been terrible. They also don't look to have a great deal of wear in them. Next time, I will definitely buy the other ones: (Bike brake pads for a mountain bike V-brake 2 pieces for bikes / bicycles
), and these: never again.
They do brake: they just do it much more noisily than the other pads, and those were cheaper.
