ABS operates before vehicle stops under normal braking conditions.
Large brake pedal vibration when ABS operates.
Large brake pedal vibration when ABS operates (refer to NOTE 2 below).

8: Brake Operation Is Abnormal

NOTE:
(1) If steering movements are made when driving at high speed, when driving on road surfaces with low frictional resistance, or when passing over bumps, the ABS may operate even though sudden braking is not being applied. Because of this, when getting information from the customer, check if the problem occurred while driving under such conditions as these.
(2) During ABS operation, changes in the feeling of the brake pedal (vibration may occur or pedal may not be able to be depressed). Such changes are due to intermittent changes in hydraulic pressure inside the brake line to prevent the wheels from locking, and is considered normal.
