Narrative:

Upon landing rollout; pilot flying reported minimal braking followed by; 'no brakes; help me.' I applied brakes from the right seat and also noted minimal brake performance while simultaneously pointing to the emergency brake lever; which the left seat pilot applied immediately. The aircraft stopped smoothly on runway 26 with plenty of runway remaining. Once the aircraft stopped; we called tower to report our brake failure. There was no other aircraft traffic. Tower gave us the option of exiting the runway or remaining where we were. After passing controls; it was determined the right seat had sufficient brake authority to exit the runway and taxi to the edge of the FBO ramp. We chose to be towed from the edge of the ramp rather than taxiing into the more congested ramp area.
