PC-24 Captain reported a PARK/EMER Brake ON Light in flight. After consulting with Maintenance and the aircraft manufacturer's support center; the flight crew were able to extinguish the light and land at destination airport.

Narrative

Referred to the QRH and executed the procedure to address the PARK/EMER Brake ON issue which there where 2 steps. 1. PARK / EMER Brake......................... Release. IF caution remains: 2. PARK / EMER Brake......................... Cycle. We applied each step and cycled the PARK/EMER Brake with both the gear up and down. These actions still did not clear the PARK/EMER Brake ON CAS Also the Brake synopsis page showed that the parking brake was on as well. We notice that every we cycled the PARK/EMER Brake the PSI would reduce. The Main Brakes were at normal pressure. We as crew deduced that if we could kept cycling the PARK/EMER Brake it would bring the pressure to zero preventing PARK/EMER Brake on landing. The QRH stated. For landing: 3. Aircraft............................................... Expect possible asymmetric braking and / or tire burst upon landing. We would only keep cycling to reduce the PARK/EMER Brake pressure. We only do this upon consulting Maintenance Control and Pilatus. After holding outside ZZZ or about 30 min to burn fuel and consulting with Maintenance Control/Pilatus thru communications we all agreed on cycling the PARK/EMER Brake. We cycled it and brought pressure to zero and confirmed the main brake were operational. We [requested priority handling] and landed with the main brakes operational only with out incident.
