I descended out of 8;000 FT for the airport. I encountered continuous light to moderate turbulence below 6;800 FT. At about 4 mile left base I went to the 'In Range Flow' for Runway 14. On about a 2 mile left base I executed the 'Landing Flow' to stabilize the ride for the passengers. Because of the winds reported on the weather station I decided to increase my approach speed from 120 to 130 KTS. I had the ILS for [Runway] 14 set in NAV 1 and stayed on glide slope to 1 dot high. Sometime during the final approach the Tower Controller called a wind check of 220 at 15 gusting to 21 varying to 280. At approximately 200 AGL; I extended the flaps to full and pulled the throttle back to 15' and took the props full forward. I touched down at about halfway down the runway and pulled the throttles to idle. I turned the aileron fully into the wind and applied full back pressure. As the plane slowed I started pumping the breaks to help the deceleration. The brakes did not slow the plane down. I increased the brake pressure and still the plane did not slow. The brakes felt very soft. I was not slowing fast enough and knew I was not going to stop by the end of the runway. At this point I noticed that there were gaps between the lights at the end of the runway. I had no ability to steer the plane to the left but I could turn to the right so I veered the plane between the lights and stopped about 10-20 FT off the end of the runway. I turned the plane around and taxied it back onto the runway and to the gate. I shut the plane down and offloaded the passengers explaining we had a brake failure. I then called the company about the brakes and the runway over run. If I could have touched down on the first third of the runway I may have been able to stop without the brakes. Also if I would have reduced the throttles to idle earlier that would have helped as well. I had considered a go around but by the time I had figured out the brakes had failed I did not feel comfortable with the amount of runway remaining to try and attempt it with a full load of passengers and the winds. I decided I was on the ground and it was the safer call than a go-around. I could have applied full flaps sooner; say at about 300 to 500 FT AGL which also would have slowed me down. I considered using Runway 32 but if the same situation had happened I would have gone off the end of the runway and then down a 30 to 50 FT hill causing much more damage and possible injures.
C402 pilot reports landing long at high speed with a strong crosswind and being unable to stop on the runway due to brake failure. Aircraft is taxied back on the runway and to the gate.
