| MLIT filing number | 1142740 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | May 31, 2018 |
| Manufacturer(s) | Honda |
| Component | Service brake — general |
| Production period | April 2015 — February 19, 2018 |
| Vehicles affected | 209,060 units |
Defect
In the brake master cylinder, the material and geometry of the secondary cup are improper. The cup may swell due to plasticizer that has leached from the reservoir tank hose into the brake fluid, and may also deform due to thermal expansion caused by engine heat during driving. This reduces sealing performance, allowing brake fluid to leak past the seal when the brake pedal is applied slowly. In the worst case, stopping distance is extended.
Corrective action
On all vehicles, replace the brake master cylinder assembly with the corrected part.

状況
ブレーキマスタシリンダにおいて、セカンダリカップの材質と形状が不適切なため、カップがリザーバタンクホースからブレーキ液中に溶け出した可塑剤により膨潤し、また、走行中のエンジンからの熱影響により膨張すると、変形することがある。そのため、シール性能が低下して、ブレーキペダルをゆっくり踏むとシール部からブレーキ液が漏れ、最悪の場合、制動距離が長くなるおそれがある。
改善措置
全車両、ブレーキマスタシリンダアッセンブリを対策品と交換する。
