- Published by: Transport Canada \(Canada\)
- Campaign number: 2026428
- Manufacturer's number: F1039
- Reported: 2026\-09\-09
- Component: Brakes
- Notification type: Safety Mfr
- Units potentially affected: 7

## What is wrong

Issue:

On a small number of trucks, the recall repairs completed by an DTNA service facility during recalls FL958 and FL966 \(Transport Canada recall nos. 2022\-626 and 2023\-051\) may not be effective. As a result, another repair is required.

On certain trucks, a software problem may not detect corrosion to the brake modulator valves. As a result, the brakes on one wheel could fully apply during automatic braking. If this happens, there could be a brake pull that can cause the truck to change direction.

Note: This problem doesn't affect the service brakes.

Safety Risk:

A brake pull that causes the vehicle to change direction suddenly can increase the risk of crash.

Corrective Actions:

Daimler Truck North America \(DTNA\) will notify owners by mail and advise you to take your truck to a DTNA authorized service facility to inspect, and if necessary, replace the brake modulator valves. The service facility will also update the vehicle software.
