When a user initiates a braking operation, an accelerator position is checked to see if the accelerator opening is about zero, a deceleration threshold value is computed based upon a brake pedal effort, the deceleration of the vehicle is obtained based upon the pedal effort, and an actual deceleration value is obtained by detecting a speed of the vehicle over time. If it is confirmed that an accelerator opening is zero, a comparison is made between the pedal-effort based deceleration threshold value and the actual deceleration are compared to determine if the brake has worn sufficiently to warrant maintenance.
