How can I know if my brake is good enough? I just feel that my brake is too soft?? When I press the pedal to stop, yes, the car stop, but if I use a little more force to press the pedal, the padel still can go down. It seems that the padel has a gap (slack) between the position of car stop and the postion of all way down. Is this normal? Normally, how deep that you press the pedal and then you can feel the brake force? Just a little bit or??
