Peterbilt recall: Service brakes, air
What is wrong
PACCAR Incorporated (PACCAR) is recalling certain 2027 Peterbilt 548 trucks. The front brake valve and hoses may be the incorrect size, which can delay the rear service brake application and release, as well as the trailer gladhand application times. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 121, "Air Brake Systems."
What could happen
Delayed brake response time can increase the risk of a crash.
The fix
Dealers will replace the front brake valves and hoses, free of charge. Owner notification letters were mailed October 21, 2026. Owners may contact Peterbilt's customer service at 1-940-591-4220. PACCAR's number for this recall is 26PACF.
