Narrative:

During aircraft run-up; a popping noise was heard inside the cockpit and the aircraft began to roll forward. When realization that brakes had failed and that aircraft was unable to stop; throttle was pulled to idle and tower was notified that aircraft was rolling onto the runway. Tower issued a go-around to an aircraft setting up to land. Used nose wheel steering to attempt to turn away from runway but the aircraft still rolled onto and came to a stop on the side. After stopping for a moment power was used to relocate the aircraft back into the run-up area as to minimize disturbance to tower operations. Explained to tower what had occurred and decided it was best to shutdown the aircraft in the run-up area and be towed to a maintenance facility on the field. Upon inspection on shutdown there was a prominent smell of hydraulic fluid and hydraulic fluid could be found sprayed around the cockpit near the rudder pedals. Maintenance found that the pop was the left brake linings failing at the rivets and breaking away.
