I have used Asuki disc pads on my 2007 city and was very satisfied with them, I replaced them after 55,000 km on my city of which at least 30,000 km was on a highways/motorways. Currently I am using MK disc pads on my swift and haven't had any problems with them, been using them for over 34,000 km now and haven't had any issues. I get my brakes serviced every 10,000 km. MK and Asuki are both good brands, provided you get them genuine from an official distributor and not from any round the corner auto parts store.
