Passenger Carrier Vehicle Inspection Procedure - Brake Inspection Update

The current Passenger Carrier Vehicle Inspection Procedure does not contain the detailed brake inspection information that is included in the current NAS Level I Inspection Procedure. For consistency purposes, I am requesting the addition of pushrod measurement information, as well as disc brake information to be included in Steps 17 and 18. Additionally, the air pressure in Step 16 should be 90-100 psi (620-690 kPa) and the transmission should be in neutral to ensure consistency with the Level I Procedure.

While there are some differences between a Passenger Carrier Vehicle Inspection and a NAS Level I inspection, the procedures should be consistent whenever possible. Modifying Step 16, 17, and 18 to include additional brake information will enhance standardization between the Passenger Carrier Vehicle Inspection and the NAS Level I Inspection Procedures.

Modify Step 16 to read: • Place ramps either in front of or behind the wheels, as appropriate. • Direct the driver to drive carefully up the ramps and stop at the top. • Insert chock blocks at the front and rear of the drive wheels. Instruct the driver to place the transmission in neutral, release the brakes, ensure air pressure is 90-100 psi (620-690 kPa), and turn off the engine. Modify Step 17 to read: • Check the steering system, front suspension, and frame. • Inspect drum or disc brake components and ensure brake linings contact the drum or disc. • Mark, measure, and record the pushrod travel (if applicable). Modify Step 18 to read: • Check the rear suspension, frame, fuel tank, tag axle, and driveline/driveshaft. • Inspect drum or disc brake components and ensure brake linings contact the drum or disc. • Mark, measure, and record the pushrod travel (if applicable).
