I will be replacing my brake pads soon. Right now I have run-of-the-mill junk brake pads on -- don't ask. On my previous Mustang I had Hawk brand street pads and I loved them. Now before I go and purchase another set of Hawk pads ($150.00 per set plus shipping), are there any other comparable brake pads for less money? Also what is the difference between the types of brake pads? Ceramic, semi-metallic, metallic, etc.??? I use my Stang on the street pretty hard plus I drag race on the weekends in the summer. I need brakes that stop me when I wanna stop, not make noise and not wear out in 6 months. Any help is highly appreciated.
