What's wrong?
The air brake system on 2012-2018 Kenworth T880 and T800 trucks uses brake control airlines to send air pressure signals through the service brake system. On trucks with the Neway ADZ tridem rear suspension, the line between two relay valves helps coordinate when the rear service brakes apply. That timing matters because air brakes depend on pressure reaching the right parts in the right sequence.
On affected trucks, that control airline was plumbed with a 3/8-inch line where the design needed a 1/4-inch line. The larger line changes the timing balance between the relay valves, so the service brakes on the tridem rear suspension do not apply in the sequence required by the air brake standard. The issue is a sizing and routing problem in the brake control plumbing, not a worn brake shoe or driver adjustment issue.
There is no warning sign before failure. The driver is not given a specific light, sound, pedal feel, or other symptom that confirms this brake timing problem before the truck is inspected or repaired.

What's the safety risk?
