I got the bike I'm riding right now used. (04 Gary Fisher Cake3) It's the first bike I've had with disks brakes. It's got Hayes HFX 9 brakes on it. I'm going to be replacing the pads and rotors as the rotors are looking a bit worn and both have a bit of a wobble to them. Plus, I don't think they're Hayes rotors. They don't look like any of the Hayes I've seen available and they don't say any manufacturer name on them. I was wondering what's the best way to break in new brakes. Also, will I need to bleed them again once I get new components in there that are full thickness? I'm still a rookie when it comes to working on my own bikes. I've always just taken it in to a shop for anything I need done. So if this is a stupid noob quesiton, sorry.
