First few days
Only had these on a few days but they are a great improvement over the originals on my truck. Easy to fit and greatly increased stopping power. I fitted them because i have a 1-ton chevy dually with a 2-ton camper and travel with my work and was wanting better stopping power on the mountain roads with less fade. These seem just the ticket. I cant say yet about whether they last longer also, but i am hoping! All in all a great buy!
