Hi all, I'm getting weird knocking sound when pressing the brake pedal, at low speeds its more prevalent and the more you press the pedal the more times it makes the knocking noise, I've had this since I bought it 2 years ago ( 2 years old with 20000 miles) and now have 35000 miles (4 years old) on it, but its getting louder now, from what I have read it is the brake actuator, is that so? and would replacing it solve the knocking sound? any advice? Thanks guys
