Issue
In the vacuum pump that supplies negative pressure to the brake booster, the internal check valve is made of an unsuitable material. Under severe cold conditions well below freezing, moisture adhering to the check valve may freeze and cause it to stick. When this occurs, negative pressure is no longer supplied to the brake booster, brake pedal effort increases, and stopping distance is extended.
Corrective action
Replace the vacuum pump on all vehicles with a corrected part. Because sourcing replacement parts requires time, replacements will be carried out beginning with vehicles in Hokkaido and the Tohoku region, then proceeding in sequence.

状況
ブレーキ倍力装置へ負圧を供給するためのバキュームポンプにおいて、内部チェックバルブの材質が不適切なため、厳寒期に氷点下を大きく下回る状況ではチェックバルブに付着した水分が凍結して固着することがある。そのため、ブレーキ倍力装置へ負圧が供給されず、ブレーキペダルの操作力が増加し、制動停止距離が伸びるおそれがある。
改善措置
全車両、バキュームポンプを対策品と交換する。なお、交換用部品の準備に時間を要するため、北海道、東北地区から順次交換を行う。
