Narrative:

After a flight of pleasure, I approached my final destination (jeffco airport) and was instructed to land on runway 11L (calm winds). I performed a normal lng and rollout. When I intended to apply the brakes to slow down, these failed, losing directional control. It made the aircraft slide to the right and veered off the runway. I knew it was not a 'life threatening' situation, but instinctively always tried to keep the aircraft from sliding. Due to the brake failure, it was impossible to control the airplane even with rudder pedals. My conclusion is that 1 brake might have worked while the other came loose and veered off. I have put a maintenance squawk at my local flying club. Days later I found brake fluid inside the aircraft and a previous squawk that was filed, that was completed but apparently never made it to the books.

Title: UPON LNDG AND APPLYING BRAKES, PA28 PLT EXPERIENCES LOSS OF DIRECTIONAL CTL DUE BRAKE FAILURE.

Narrative: AFTER A FLT OF PLEASURE, I APCHED MY FINAL DEST (JEFFCO ARPT) AND WAS INSTRUCTED TO LAND ON RWY 11L (CALM WINDS). I PERFORMED A NORMAL LNG AND ROLLOUT. WHEN I INTENDED TO APPLY THE BRAKES TO SLOW DOWN, THESE FAILED, LOSING DIRECTIONAL CTL. IT MADE THE ACFT SLIDE TO THE R AND VEERED OFF THE RWY. I KNEW IT WAS NOT A 'LIFE THREATENING' SIT, BUT INSTINCTIVELY ALWAYS TRIED TO KEEP THE ACFT FROM SLIDING. DUE TO THE BRAKE FAILURE, IT WAS IMPOSSIBLE TO CTL THE AIRPLANE EVEN WITH RUDDER PEDALS. MY CONCLUSION IS THAT 1 BRAKE MIGHT HAVE WORKED WHILE THE OTHER CAME LOOSE AND VEERED OFF. I HAVE PUT A MAINT SQUAWK AT MY LCL FLYING CLUB. DAYS LATER I FOUND BRAKE FLUID INSIDE THE ACFT AND A PREVIOUS SQUAWK THAT WAS FILED, THAT WAS COMPLETED BUT APPARENTLY NEVER MADE IT TO THE BOOKS.
