Narrative:

I just had my right tire and brake pads replaced and decided to go practice an approach or two. Taxi out indicated nothing wrong with my new brakes so I took off. I flew to aurora, shot 3 approachs and decided to land. During the rollout the right brake pedal went to the floor and no brake action resulted. I tried to pump the pedal but received no response. I continued to slow the aircraft with left brake but soon realized I would roll off the end of the runway. I pulled both mixtures to cut off and the propellers stopped but I rolled into the grass at the end knocking the lens off the runway end light. There was no damage to the aircraft and it is impossible to determine what part hit the light. I was tugged in and called the tower to see if they wanted any information. From now on I will pump the brakes on final to assure pressure and test them again after touchdown rather than aerodynamically brake first. The probable cause was air in the line and my failure to anticipate the problem.

Title: TWIN SMA HAS BRAKE FAILURE, ROLLS OFF END OF RWY.

Narrative: I JUST HAD MY R TIRE AND BRAKE PADS REPLACED AND DECIDED TO GO PRACTICE AN APCH OR TWO. TAXI OUT INDICATED NOTHING WRONG WITH MY NEW BRAKES SO I TOOK OFF. I FLEW TO AURORA, SHOT 3 APCHS AND DECIDED TO LAND. DURING THE ROLLOUT THE R BRAKE PEDAL WENT TO THE FLOOR AND NO BRAKE ACTION RESULTED. I TRIED TO PUMP THE PEDAL BUT RECEIVED NO RESPONSE. I CONTINUED TO SLOW THE ACFT WITH L BRAKE BUT SOON REALIZED I WOULD ROLL OFF THE END OF THE RWY. I PULLED BOTH MIXTURES TO CUT OFF AND THE PROPS STOPPED BUT I ROLLED INTO THE GRASS AT THE END KNOCKING THE LENS OFF THE RWY END LIGHT. THERE WAS NO DAMAGE TO THE ACFT AND IT IS IMPOSSIBLE TO DETERMINE WHAT PART HIT THE LIGHT. I WAS TUGGED IN AND CALLED THE TWR TO SEE IF THEY WANTED ANY INFO. FROM NOW ON I WILL PUMP THE BRAKES ON FINAL TO ASSURE PRESSURE AND TEST THEM AGAIN AFTER TOUCHDOWN RATHER THAN AERODYNAMICALLY BRAKE FIRST. THE PROBABLE CAUSE WAS AIR IN THE LINE AND MY FAILURE TO ANTICIPATE THE PROB.
