your are absolutely right, The Frixa brand brake pads are for Rs. 800 from Sadar, and for Rs. 1250 from Hyundai Sowan, so avoid them, i have also a bad experience with Sowan motors mechanical works, they guy over there devided outer CV joint greases and used it for inner one as well, how much they know as evident from this act.
by the way good decision to change the belts on time.
