Narrative: Prior to departing we jointly reviewed the NOTAMs and took note that the main runway would be closed at our arrival time. As such we ran preflight calculations for landing in various conditions on [another runway]. We were satisfied that we could land on [the other runway] in the dry but would not land there if it started raining prior to our arrival. After an uneventful flight we prepared for the RNAV approach [to the other runway]. During gear extension we noticed nothing abnormal. The approach was stable and nominal. Upon contact with the tower I asked if the runway was dry and the tower stated that it 'looked pretty dry'. Once breaking out of the overcast layer we could clearly observe that the runway was dry as well as the surrounding areas and that the rain had not yet began.At touchdown the PF applied the brakes. I initially noticed nothing abnormal for about 1-2 seconds at which time I began to think that we did not have normal deceleration. The BRK FAIL CAS message then illuminated; I stated out loud 'brake fail CAS'. At the same time the PF had stated 'the brakes are gone' he then stated  'emergency brakes' to which I agreed. He began pulling the emergency brake handle; the tires appeared to lock immediately. The tower then announced 'you have strong smoke from your main gear.'  I felt what I assumed was the right main blowing as the aircraft dropped on the right side [and] I stated 'we lost the right gear.' The PF was clearly correcting for the drift to the right and began a more aggressive correction. The aircraft came to a stop with the nose aimed approx 10 degrees right of centerline with the entire aircraft on the right side of the runway but still on the pavement. I told tower we would be stopping on the runway and asked if they could see any fire. They stated no smoke or fire and offered assistance.  We declined. We discussed if we wanted to run the emergency evacuation checklist or the normal shutdown checks; we elected to run the normal shutdown checklist and then exited the aircraft.


Second narrative: First flight of our trip as a crew and with new airplane. Aircraft out of maintenance this morning for an unrelated (so far as we could tell) autopilot; yaw damper; ventral rudder fail write up. Prior to leaving the terminal; we briefed in accordance with all applicable sections of the AOM as to what to expect during arrival. Main landing runway was NOTAM'ed out of service; shorter runway is not available ever for jet traffic. [Shorter] with over 5;000 feet of runway was the runway we'd use via the RNAV approach. Runway was dry ahead of an approaching line of rain that would not have been a factor for us if staying on the original schedule.We had topped off the fuel to 5;230 LBS and had plenty of fuel to continue through with fuel on board. We landed at 16;400 LBS gross with approximately 4;200 LBS of fuel onboard. Dry runway conditions were confirmed by the tower prior to descent from the FAF. Autopilot and yaw damper were off and the aircraft was stable by 1000 ft AGL. Touchdown was normal; once the nose touched down I applied normal braking pressure to the pedal brakes. Braking appeared to start normally at a lower level and prior to the phase of braking where one or both of the main brakes increase braking effort tremendously; the braking pressure being applied went away and the BRAKE FAIL CAS illuminated. The First Officer said; 'BRAKE FAIL CAS' and I said 'BRAKES GONE'. I did not release pressure on the brake pedals; instead increasing to maximum deflection resulting in zero braking from the aircraft. I called 'GOING TO EMER BRAKING' and reached over to grab the EMER BRAKE pull handle. I slowly raised the handle until I felt SOME gentle braking and left the handle where it was trying to be careful not to burst tires. As the aircraft slowed; directional control was very difficult but I managed to stay just right of centerline just barely canted to the left into the wind when we stopped. I did feel the right main burst and the First Officer confirmed it. Once stopped; I set the parking brake; we checked on each other; looked behind us and saw nothing in the cabin unsafe. Talked to tower to let them know we were disabled and unable to taxi and to send personnel to assist. We ran a securing checklist and went dark aircraft. The brake fail occurrences in the PHENOM must be [looked into]. This was a textbook PHENOM brake fail event. We should have had brakes and we didn't. On a shorter; contaminated runway or a more narrow runway; we'd have exited pavement.

Second callback: The Captain indicated that main brake failures on the Phenom 300 occur too frequently but are usually annunciated by the CAS when the gear is extended; giving the crew some warning. The system is similar to the Phenom 100 brake system which also has a history of failures. The aircraft has a Brake Control Unit (BCU) that controls brake application electronically when the brake pedals are depressed. The BCU has been the subject of service bulletins and upgrades over the years but the problem persists. He believes that there should be a second BCU to allow the crew to switch in the event of failure.

Synopsis: Embraer Phenom 300 flight crew experienced a brake failure after touchdown. Emergency air brakes were used to stop but the right brake locked up and the right tire burst.
