- With engine off, apply full brake pressure and hold for 1 minute
- Air pressure drop should not exceed 4 psi (single vehicle)
- Apply and release brakes, check for prompt application and release
- Check for leaks around brake chambers and connections
- Verify low air warning device activates between 55-75 psi
- Continue reducing air pressure to verify spring brakes activate (30-45 psi)
- Check slack adjuster travel (should not exceed manufacturer specifications)
Fifth Wheel Coupling Inspection
- Ensure trailer is properly supported before inspection
- Check fifth wheel for cracks, excessive wear, and proper lubrication
- Verify jaws close completely around kingpin
- Check that release handle is in locked position with safety latch engaged
- Verify no gap between upper and lower fifth wheel plates
- Check mounting bolts, brackets, and pins for security
- Inspect air and electrical lines for proper connection and condition
- Perform tug test to verify secure coupling
Tire and Wheel Inspection
- Check tire inflation with a gauge (not by kicking or visual inspection)
- Measure tread depth with proper gauge (min. 4/32" steer, 2/32" drive tires)
- Inspect sidewalls for cuts, bulges, and penetrations
- Check for signs of misalignment, uneven wear, or flat spots
