Overview
| MLIT filing number | 1149750 |
|---|---|
| Type | Statutory Recall (government-mandated recall) |
| Date filed | June 17, 2021 |
| Manufacturer(s) | Isuzu, UD Trucks |
| Component | Parking Brake (General) |
| Production period | July 2016 — November 2019 |
| Vehicles affected | 43,702 units |
Defect
In the brake system of large and medium trucks, the plastic piston inside the parking brake relay valve is made of an unsuitable material. Moisture in the air circuit causes the piston to hydrolyze and fracture under brake air pressure. This may result in air leaks from the brake valve, inability to release the parking brake, or brake drag.
Corrective action
Replace the affected piston with a non-defective part on all vehicles.
