Very interesting, especially - - - - -
There is only one way to prevent this sort of thing - following proper break
in procedures for both pad and disc and use the correct pad for your driving
style and conditions.
During pad or disc break-in, do not come to a complete stop, so plan where
and when you do this procedure with care and concern for yourself and the
safety of others. If you come to a complete stop before the break-in process
is completed there is the chance for non-uniform pad material transfer or
pad imprinting to take place and the results will be what the whole process
is trying to avoid. Game over.
Keep reading. There is more after "game over."
I had a minivan that was notorious for "warping" its rotors. It got so
bad once that I was ready replace the rotors and pads, so I decided just
for fun to try a few really hard sopts in sequence. I read, maybe in a
different article, that this could reverse some of the uneven transfer
of pad material.
So, I went out to a back country road with virtually no traffic and made
10 or so hard stops from 60 MPH to 5 or so with some cooling time in
between. Presto! The "warped" brakes were now virtually gone. There
was some very minor pulsation still present, but almost negligible. I
ran those brakes and rotors several thousand more miles without trouble.
