Aborted Takeoff
During the takeoff roll, the pilot noticed a vibration and a slight pulling to the left. The brakes and engine had been checked with nothing noted, but the pilot decided to abort the takeoff. The aircraft was allowed to roll to a stop without using brakes.
Taxi Fire
After stopping and detecting nothing unusual, the pilot decided to attempt another takeoff. While taxiing and checking the brakes, blue-gray smoke came out of the wheels, followed by flames from the right wheel.
Attempt to Stop
An attempt to stop the aircraft was ineffectual, as the pilot stated there was no pressure in the brake pedals. The aircraft rolled into a dry grass area and burned.
