thats the most common cause. other causes can be bad bedding in
of new brake pads and poor installation of brake rotors.
drilled and slotted rotors do help to dissipate heat, but at the
same time, they are usually poorer heat sinks compared to stock
rotors (imagine 2 rotors of the same size, one with holes and one
without, which one got more metal?) and would therefore warp more
easily. there is always this constant debate on rate of heat
dissipation of drilled/slotted disks versus heat sink of stock
rotors. my take on the matter is dat unless u upgrade to a larger
disk, its not advisable to have drilled disks of the original size
installed.
brake fade is another issue dats linked somewhat to the heat
retention capabilities of ur rotors. braking translates kinetic
energy to thermal energy. this energy is shared by the brakes and
the rotors. depending on the heat range of ur pads, and as long as
the combination of heat transfer between the 2 elements dun exceed
this range, theoretically u should not experience brake fade.
