From the field · October 19, 2026

Air pressure lost.
Truck back in service.

A 2020 Kenworth T880 lost secondary air pressure on the road. TCS found a broken pipe between the valve and secondary air tank, removed the tank and valve, and extracted the damaged pipe.

After sourcing the replacement, our technician reassembled the tank, valve and air lines at the breakdown location, then checked for leaks with the truck running.
