Narrative:
Departed N10 for aircraft familiarization flight and to check vors. After completing some air work, went to pne to check vors. Landed at pne, made check of vors and departed. Arrived back at N10 and made a normal left traffic pattern for runway 27. Airspeed over the end of the runway was 95 KTS and touchdown was normal. Upon application of brakes it was discovered I didn't have any, even though they had worked at pne and it felt like I had pressure when I checked them in the pattern at N10 after gear extension. By standing on the brakes I did get some braking, but with a downhill runway I could not prevent aircraft from going off end. I was slow enough that damage to aircraft was minor and I was not hurt. It would be nice to have either a light or a gauge that would tell pilots when brake fluid pressure is not sufficient to stop aircraft.

Title: CPR SMT BRAKE FAILURE AFTER LNDG. PLT REPORTER WAS RETURNING FROM AN ACFT FAMILIARIZATION FLT.
Narrative: DEPARTED N10 FOR ACFT FAMILIARIZATION FLT AND TO CHECK VORS. AFTER COMPLETING SOME AIR WORK, WENT TO PNE TO CHECK VORS. LANDED AT PNE, MADE CHECK OF VORS AND DEPARTED. ARRIVED BACK AT N10 AND MADE A NORMAL LEFT TFC PATTERN FOR RWY 27. AIRSPEED OVER THE END OF THE RWY WAS 95 KTS AND TOUCHDOWN WAS NORMAL. UPON APPLICATION OF BRAKES IT WAS DISCOVERED I DIDN'T HAVE ANY, EVEN THOUGH THEY HAD WORKED AT PNE AND IT FELT LIKE I HAD PRESSURE WHEN I CHECKED THEM IN THE PATTERN AT N10 AFTER GEAR EXTENSION. BY STANDING ON THE BRAKES I DID GET SOME BRAKING, BUT WITH A DOWNHILL RWY I COULD NOT PREVENT ACFT FROM GOING OFF END. I WAS SLOW ENOUGH THAT DAMAGE TO ACFT WAS MINOR AND I WAS NOT HURT. IT WOULD BE NICE TO HAVE EITHER A LIGHT OR A GAUGE THAT WOULD TELL PLTS WHEN BRAKE FLUID PRESSURE IS NOT SUFFICIENT TO STOP ACFT.
