Hazard
The check valve material that maintains vacuum in the brake booster is inappropriate, causing the valve to stick in the closed position during parking after engine shutdown. As a result, when the brake pedal is pressed during low-speed driving without accelerator input immediately after engine start, the check valve may not open, leading to insufficient vacuum in the brake booster at the initial brake application and increased brake pedal operating force.

制動倍力装置の負圧を保持するチェックバルブの材料が不適切なため、エンジン停止後の駐停車中に当該バルブが閉じた状態で貼り付くことがある。そのため、始動直後のアクセルペダルを踏まない状態での低速走行中にブレーキペダルを踏んでも、チェックバルブが開かず、最初の制動時に制動倍力装置の負圧が不足し、ブレーキペダルの操作力が増大するおそれがある。
Remedy
Replace the check valve with corrective parts on all vehicles.
