In this study, we investigated a new type of groan noise that is different from other conventional types of groan noises during braking. This groan noise occurs immediately after stopping the vehicle. We investigated the behaviors of the pads and caliper on the vehicle with two types of pads. By comparing the data, we assumed that μ characteristics of those pads during the stopping event are different. Then we examined the friction surface of the pads in order to study the root cause. In conclusion, we determined that the shape of the contact plateaus of the brake pad surface contributed to this groan noise.
