Hi Jim,

You are the words of wisdom.
- I will replace the rotors (I already ordered them from the best Toyota
Internet dealership in the USA according to these newsgroups).
- I will replace the pads and hardware too (already ordered them too).
- I agree it is important to check that the four pistons in each caliper
are moving freely as the disc thickness variation (DTV) is what caused the
runout in the first place (not heating & cooling warpage).

I'm not just interested in fixing my brakes (otherwise I'd just take them
to any mechanic on the block). I'm interested in learning why it happened
and how to prevent it from happening in the future. And how to diagnose
the problem properly.

For example, if I follow your (correct) advice to check caliper and piston
movement, it begs the question (which is NOT in the shop manuals)!

How does one check that the front 2 calipers & 8 pistons move freely?
