The product
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."
