Hello, I drive an i30cw CRDI, year 2014 with 110hp. In my second, premature inspection (all made only with Hyundai) and a total running power of only 30,000km, the rear brake discs are very noisy and worn and the brake pads almost completely down. Is this normal with the i30? Before, no I almost never really go into the iron, driving a lot of city highway, looking ahead and brake on my daily highway ride from 110 to 40km/h only with motor brake. the rear brake discs and pads kept? By the way, my car I picked up at the end of December from inspection at Hyundai and only a few days later the brakes at the front began to squeak at a slight tap. Whenever I gently brake it only squeaks loudly at the front. Does not have to be fixed at an inspection too?
