wow that was awfully condesending
JPI is here to help
your buddy isn't
you don't have to belive him that is up to you but you also don't know him either
but i wouldn;t take someones word just because they say "i know this"
as there are different procedures for different cars and situations
you only see it as a narrow affect band of treatment
not the whole reaonsing behind the final decsion
a techintion has to look at the overall situation
I also see no need for cutting a rotor on a car ,it is a waste of time
just pull the damn thing off and replace them, that is the best way as cut rotors always have a tendency to warp much faster as they are unequal thickness per side always which is why they were cut
