So I have noticed that there's clicking sound coming from the front right wheel. It only happens at low speed(20-30kmh) when I'm going straight, not turning.
So my rotors are bent, I have thought about its because of the bent rotors which causes the problem. When I hear those clicking sound, I tap on the brake little bit, and the clicking sound goes away...... but when I release it, the noise comes back. Anyone has the same problem? I know most people have this problem when they make a turn.
