If those MK are local, they are leather. Leather tends to overheat and 'fade' (try searching for 'brake fade').
If you use MK Japan, they are most probably carbon, but sorry I don't have any experience.
I've got good experience with Schnieder (Malaysia), Asuki (Japan) and Nippon (Japan). In Karachi, Yamamoto (Malaysia) are also popular but I don't have first hand experience.
Try Nippon or something else, but don't pay heed if the shopkeeper tells you not to buy carbon brake pads. Carbon brake pads last longer so few shopkeepers want you to buy them.
Take note, Nippon last longer but also fade more than Schnieder. (However they only fade after some very high-performance driving, not like the leather ones who fade every other corner).
Also, performance brakes are meant for the track, and their optimum operating temperature is on the higher side. What I mean is there should be a warm-up session for the brakes, tyres, engine and fluids to come up to the operating temperature. This implies that you'd find extremely lousy braking while going to grocer's if using performance brake pads. And other, more sedate drivers using the same vehicle could cause accidents because the brake won't grip that much when cold.
P.S: Ultimately all brakes fade unless you buy that carbon-fibre ceramic set from Ferrari for US$4000.
