unfortunately, I can't forsee any way brakes, or rotors can affect the bearing..
NOT pressing the bearing in, and hammering it in WILL cause it to go bad in a VERY short time.
BTW:
try looking in my how-to post under duratec maintenance, and SEE what you can and can't do.
As long as you can read the English language, you can do this.
Ask anyone, my how-to's are written from a NOVICE/NOOB/IDIOT/FIRST-TIMER perspective. If you can read and look at a picture book, you can change the bearing, or pull the hub. ALL tools required are listed.. those you DON'T have can be borrowed from a parts store for a deposit.. (returned upon bringing them back... so.. free...)
DON'T limit yourself.. you can do this.
