|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | October 7, 2004 |
| Manufacturer(s) | Mitsubishi |
| Component | Parking Brake (General) |
| Production period | December 11, 1992 — July 15, 1998 |
| Vehicles affected | 2,917 units |
Defect
On vehicles equipped with spring-type parking brakes, the internal dimensions of the spring chamber and the spring seat geometry are incorrect. When the spring is compressed to release the parking brake, the springs contact each other or contact the chamber body, causing the spring coating to peel and rust to form. Continued operation in this condition may cause the spring to fracture. In the worst case, the fractured spring reduces parking brake effectiveness, or the fractured spring end damages the diaphragm, causing an air leak that prevents the parking brake from releasing.
Corrective action
On all vehicles, replace the brake chamber as an assembly with a corrected part. In addition, affix a sticker to the maintenance booklet of each affected vehicle indicating that the spring must be inspected every two years.

状況
スプリング式駐車ブレーキ装着車において、スプリングを格納している容器（チャンバー） 内部の寸法ならびにスプリングの台座形状が不適切なため、スプリング圧縮（駐車ブレー キ開放）時にスプリング同士又はスプリングとチャンバー本体が干渉し、スプリングの塗 装が剥がれ、錆びが発生するものがある。そのため、そのままの状態で使用を続けると、 最悪の場合、当該部分でスプリングが折損し、駐車ブレーキの効きが悪くなる、又は折損 したスプリング端部でダイアフラムが損傷すると、エア洩れが発生し、駐車ブレーキが解 除できなくなるおそれがある。
改善措置
全車両、ブレーキチャンバーをアッセンブリで対策品と交換する。また、対象車のメンテ ナンスノート・整備手帳に、当該スプリングを２年毎に点検する旨のシールを追加する。
