This filing is one of 18 UD Trucks notifications from 2017 in this archive.

Defect
In the brake system, the brake air tube is improperly routed, allowing it to contact the propeller shaft when driving over severely uneven road surfaces. Continued use in this condition may cause the tube to sustain damage, resulting in an air leak and the brake warning light illuminating. In the worst case, braking force may decrease.
Corrective action
On all vehicles, replace the brake air tube connection connector with a corrected part (L-shaped type) and reroute the tube. If the tube is found to be damaged, replace it with a serviceable unit.
