My analysis of this product showed that it`s just plain poor quality. I installed these brakes on my motorcycle and within a few months, they started making a terrible squealing noise. Additionally, they wore down much faster than expected, and I had to replace them again within a year. The only positive aspect is that they are advertised as professional-grade, but that's not enough to make up for their numerous downsides .Avoid these brakes if you want reliable, long-lasting automotive parts foSee full review
