Yes, I'd start with bedding the brakes first, OP. Just find the directions from your pad manufacturer's site, as I hear protocols vary slightly from one pad to the other...but basically what was said above. Use them hard on the highway...slowing from 60-10 or so a few times with a minute in between...and then after they're hot, don't use the brakes until rotors cool down.
You can collect materials, I hear, from holding the pad onto rotors when they're hot...so I try not to do that. I'll creep up at a stop to ensure the rotor moves under pads.
As desperate as this sounds, in comedy, 'likes' and 'views,' 'friends,' and 'retweets' really help. If I've ever helped you, please help me by friending, liking, viewing, and retweeting. It makes others think I have a following...it'll take you a minute or less. If you could, I'd really appreciate it!
