1 good one out of three - not good. My Focus had a failed rear wheel bearing and I decided to replace both with this product even though only one was defective. I've used this class of pads and liked them so I figured they must be good. Revain only had one in stock so I ordered it and fitted it in place of the failed bearing and it has been working flawlessly for a couple of months now. Ordered a second one as soon as they got back in stock and when I put it on the car it had bad bearing and the drum wasn't 'genuine' and braked hard and throbbing with a loud bang. Removed, old one in, the problems are gone. Got a replacement 2 weeks later, installed it and it works exactly the same. Gave 2 stars because the one that works is fine, but a good drum out of three is NOT GOOD. Follow-up: I returned this item to Revain for credit instead of a replacement, but they tried to charge me for the restocking. This later changed when I contacted them about this. Good customer service but shouldn't have tried to charge him in the first place.
