[V8] UFO brake pads

[toml99 at todomundo.com]

So, I got a chance to pull the wheels off today, and the rotors look  
smooth.  I re-verified the mileage, and the pads and rotors only have  
30K on them.  I measured the pads, and therein lies the question.   
The book says "pad thickness new 12mm/max wear 2mm....then says "when  
brake pad thickness,including backing plate is 7mm, pads should be  
replaced".

[I take that to mean that the friction "pad" part is 12mm thick new,  
and can wear down to 2mm?]

   I measured all of them(front) and the pad thickness was  
7.8/6.7....6.3/7.6(left to right).  Then it says..."when pad  
thickness including backing plate is 7mm...replace"......Mine were  
12.4/11.2...10.8/11.2.  Since I just recently bought my first real  
caliper when I did the timing belt, this is the first time in my life  
I think that I've ever actually measured a brake pad.  I saw nothing  
obvious that would make that nasty growl like rivets wearing thru the  
pads and grinding on the rotors....The wires were all replaced with  
the rotors/pads, and there's no brake light happening.  Noise only  
happens when pressing harder on the brakes and coming to a slow  
stop.  Everything looks pretty happy to me, just wanted to make sure  
I was interpreting the book correctly/make sure the now rare rotors  
weren't getting trashed.  Maybe there's a bit of something stuck  
under one of the pads?....Regardless, I'll probably get a set of pads 
(or 3) while I'm thinking about it and before they get rare  
also....Still stop quick and smooth......Sincerely, Tom
