Narrative:
Before landing checklist completed. All normal indications. Stable approach, touchdown on speed approximately at the 500 ft point. When braking was attempted, zero braking. Attempted to deploy brake parachute with no result. Continued to attempt braking. Declared emergency. Left runway, left gear hit concrete runway sign foundation and broke off. Engine was shut down prior to coming to rest. No injuries, no fire. This aircraft uses differential braking to steer. No brakes, no steering ability. I could have shut down the engine a little sooner, but then would have lost hydraulic pressure and been totally dependent upon brake accumulator pressure -- with antiskid working (had the brakes decided to work) accumulator pressure would not last long. I considered raising the gear, but thought that once on the grass the wheels sinking in would provide better deceleration. I should perhaps have jettisoned the canopy to aid rescue in the event of rolling over.

Title: AN AGED MIL FIGHTER CPR JET RUNS OFF THE RWY WHEN THE BRAKES AND AUX CHUTE FAILS TO DEPLOY WHEN THE PLT ATTEMPTS ACTUATION ON TOUCHDOWN AT GSO, NC.
Narrative: BEFORE LNDG CHKLIST COMPLETED. ALL NORMAL INDICATIONS. STABLE APCH, TOUCHDOWN ON SPD APPROX AT THE 500 FT POINT. WHEN BRAKING WAS ATTEMPTED, ZERO BRAKING. ATTEMPTED TO DEPLOY BRAKE PARACHUTE WITH NO RESULT. CONTINUED TO ATTEMPT BRAKING. DECLARED EMER. LEFT RWY, L GEAR HIT CONCRETE RWY SIGN FOUNDATION AND BROKE OFF. ENG WAS SHUT DOWN PRIOR TO COMING TO REST. NO INJURIES, NO FIRE. THIS ACFT USES DIFFERENTIAL BRAKING TO STEER. NO BRAKES, NO STEERING ABILITY. I COULD HAVE SHUT DOWN THE ENG A LITTLE SOONER, BUT THEN WOULD HAVE LOST HYD PRESSURE AND BEEN TOTALLY DEPENDENT UPON BRAKE ACCUMULATOR PRESSURE -- WITH ANTISKID WORKING (HAD THE BRAKES DECIDED TO WORK) ACCUMULATOR PRESSURE WOULD NOT LAST LONG. I CONSIDERED RAISING THE GEAR, BUT THOUGHT THAT ONCE ON THE GRASS THE WHEELS SINKING IN WOULD PROVIDE BETTER DECELERATION. I SHOULD PERHAPS HAVE JETTISONED THE CANOPY TO AID RESCUE IN THE EVENT OF ROLLING OVER.
