The adjustment procedures for parking brake failure on an LS Tractor MT458 include:

1. Stop the tractor on a level surface.
2. Disengage the PTO and place all transmission shift levers in neutral.
3. Lower mounted implements to the ground.
4. Apply the parking brake.
5. Stop the engine and remove the ignition key.
6. Wait for the engine and all moving parts to stop before leaving the operator’s station.
7. Use wheel chocks when parking on a slope.

No specific parking brake adjustment steps are detailed, but these procedures ensure safe parking and may help identify improper brake engagement.
