Overview
| MLIT filing number | 1139290 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | December 1, 2016 |
| Manufacturer(s) | UD Trucks |
| Component | Primary Brake System |
| Production period | January 10, 2005 — August 2015 |
| Vehicles affected | 16,340 units |
Defect
On large trucks, the rear brake chamber has insufficient strength. Vibration frequencies generated when traveling at 80 km/h over highway rumble strips may cause cracks to develop in the brake chamber. If the vehicle continues to be used in this condition, the cracks will propagate and, in the worst case, the chamber may separate.
Corrective action
On all vehicles, the rear brake chambers will be inspected. If an unmodified part is found installed, the brake chamber assembly will be replaced with a corrected part.

状況
大型トラックの後輪制動装置において、ブレーキチャンバーの強度が不足しているため、高速道路における路側帯との区分線（バイブラライン）上を時速８０ｋｍ／ｈで走行した際の振動周波数によってブレーキチャンバーに亀裂が生じることがある。そのため、そのままの状態で使用を続けると亀裂が進行し、最悪の場合、当該チャンバーが分離するおそれがある。
改善措置
全車両、後輪のブレーキチャンバーを確認し、未対策品が装着されている場合には、ブレーキチャンバーアッセンブリを対策品と交換する。
