I have had booster brakes in the past and they work great. What really sucks about this purchase is that my package was "missorted" at UPS when they shipped my package. My package was delivered to my city and then suddenly sent back to the seller due to mis-sorting on delivery. I thought ok I'll try to order them again. Long before you know it, the price has been raised higher than it originally was. Kind of sucks when I really needed brakes for my daily sedan, especially when they're grinding metal on metal. I don't know whose fault it was (Amazon, UPS, Powerstop) but it was definitely the downside of my day.
