Narrative:

I was given vectors to intercept the localizer and was cleared for an INS approach to runway 23 which is 7401' long. I was close to the airport when I received the approach clearance, and although I immediately began my descent on the localizer, I was too high and unable to descend quickly enough to intercept the G/south. As a result I touched down approximately 1/3 of the way down the runway. I then had unexpected trouble with the right brake. It apparently was not functioning, and although I reversed the propellers and applied hard pressure to both brakes, the aircraft would not slow down as it should, and it began pulling to the left. The aircraft continued rolling past the end of the runway and off to the left side into the grass, and continued onto the adjoining taxiway. I was then able to stop the aircraft and shut down both engines. The left tires had failed from friction with the runway, and the left wheels were damaged from contact with the runway. Although there remained sufficient runway from the T/D point to make a safe landing under normal circumstances, I believe that my ability to stop the aircraft on the runway after the brake failure was compromised by the fact that the T/D point was beyond the normal T/D zone. This incident may possibly have been avoided if I had executed a go around, and not attempted to land from a higher than normal glide path.

Title: SMT PLT MAKES HIGH APCH, HAS BRAKING PROBLEM AND RUNS OFF RWY.

Narrative: I WAS GIVEN VECTORS TO INTERCEPT THE LOC AND WAS CLRED FOR AN INS APCH TO RWY 23 WHICH IS 7401' LONG. I WAS CLOSE TO THE ARPT WHEN I RECEIVED THE APCH CLRNC, AND ALTHOUGH I IMMEDIATELY BEGAN MY DSNT ON THE LOC, I WAS TOO HIGH AND UNABLE TO DSND QUICKLY ENOUGH TO INTERCEPT THE G/S. AS A RESULT I TOUCHED DOWN APPROX 1/3 OF THE WAY DOWN THE RWY. I THEN HAD UNEXPECTED TROUBLE WITH THE RIGHT BRAKE. IT APPARENTLY WAS NOT FUNCTIONING, AND ALTHOUGH I REVERSED THE PROPS AND APPLIED HARD PRESSURE TO BOTH BRAKES, THE ACFT WOULD NOT SLOW DOWN AS IT SHOULD, AND IT BEGAN PULLING TO THE LEFT. THE ACFT CONTINUED ROLLING PAST THE END OF THE RWY AND OFF TO THE LEFT SIDE INTO THE GRASS, AND CONTINUED ONTO THE ADJOINING TXWY. I WAS THEN ABLE TO STOP THE ACFT AND SHUT DOWN BOTH ENGS. THE LEFT TIRES HAD FAILED FROM FRICTION WITH THE RWY, AND THE LEFT WHEELS WERE DAMAGED FROM CONTACT WITH THE RWY. ALTHOUGH THERE REMAINED SUFFICIENT RWY FROM THE T/D POINT TO MAKE A SAFE LNDG UNDER NORMAL CIRCUMSTANCES, I BELIEVE THAT MY ABILITY TO STOP THE ACFT ON THE RWY AFTER THE BRAKE FAILURE WAS COMPROMISED BY THE FACT THAT THE T/D POINT WAS BEYOND THE NORMAL T/D ZONE. THIS INCIDENT MAY POSSIBLY HAVE BEEN AVOIDED IF I HAD EXECUTED A GAR, AND NOT ATTEMPTED TO LAND FROM A HIGHER THAN NORMAL GLIDE PATH.
