this morning while i was driving my elantra 2012, i heard a ''tik'' or ''tak'' noise while i press the pedal brake. i can feel the noise through the A/T throttle while i press the brake. the noise is there when i press the pedal brake even in ''P'' mode. i have no clue about the source of noise. the car is moving ok, no probs with acceleration, braking or shifting gears. i have done only just under 7000km. do u have any clue for it?
