If you're brakes were dragging make sure and put your rotors on a lathe and check the tolerances on those...brakes take motion and dissipate that energy into heat to provide stopping...however...too much heat and those rotors will warp which can screw with you bad.
Also...check the caliper pistons and seals...make sure they're clean and not pitted/damaged and are clean.
Check your master cylinder...that relief hole is CRITICAL for relieving your brakes...if it's clogged even partially...it will mess you up!
Regular brake maintenance is a necessity...these birds can build up some speed quick...and you need to be able to stop it eventually Change your pads...and don't forget to change the fluid and bleed those brakes!
