I just caught the rotor advice and just wanted to add, that cracking is generally ok. Once you start with small cracking, keep an important eye on the overall thickness of the rotor. As it gets narrower, the cracks will be more worrisome. Measure them now before you throw them out.

Hawk pads do get brittle, it's a Hawk blue/HT-10/14 characteristics. The best pads I've had are ones that I'm real careful on with warm up and cool down. I once cracked a set of HT-10's doing an autox.
