These brake pad have about 1000 miles on them so far. I've been using the less expensive D2Moto pads for the past few years, but decided to try the sintered pads this time. They have great stopping power, but are noisier than the previous pads. At this price, I change them out every 30,000-40,000 miles (1 1/2 - 2 yrs). Great price, fast shipping, good fit.
