What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot reported after landing during the rollout on runway 16 at kbpt his brakes appeared to be ineffective. Resulting in the aircraft exiting the paved surface of the runway onto the grass 15-20 feet beyond at the departure end of runway 16. Photos show tire marks from the right main caused by a heavy braking action but none were visible following the path of the left main tires. Post inspections showed the left anti skid sensor failed and the right brake was not developing pressure.
