technical brake rotor wear questions.

sipes216 · Nov 3, 2007

allright, i've just got a couple really simple yet complex questions for ya'll to anwer, if you can.

for a 2002 b5.5 (duh) FWD V6, can someone please give me the front and rear brake rotor inch-thousandths minimum wear limit?

for those who don't quite understand me, i'm asking for their minimum thickness they can get to, before change is advisable. this is one of those readings meant to be obtained with a 0-1 micrometer.

It is stamped on the rotor but I don't remember it. We can check today when we tear the car apart at the GTG.

Here are the rear disc specs

Vented rear disc is 20mm (.787) minimum
Solid rear disc is 8mm (.315) minimum

Front brakes have 5 different options available as follows
C54 ( 280 MM (11.023) dia rotor )
FN3 ( 288 MM (11.338) or 282.5 MM (11.122) dia rotor )
HP-2 ( 321 MM (12.638) dia rotor )
2FN ( 334 MM (13.150) dia rotor )

VIN # required unless you know what you got.

Only the W8s got the vented rears

HP-2 is only on US/Canadian spec W8s
2FN is only on Euro-spec W8s w/ Sports Package.
A 2002 V6 almost certainly has the FN3, most likely 288mm rotor
