Narrative:
An east landing in VFR conditions with an estimated wind from 090 at 10 KTS, hot day approximately 90 degrees F, heavy aircraft but under maximum landing weight, resulting in a high reference and approximately 3100 ft landing roll with a runway of 5000 ft. Touchdown occurred approximately 1400 ft down the runway. Brakes, spoilers and thrust reversers were used in a very timely manner. However, deceleration was slower than normal. The PNF applied brakes noting the left brake was not operating normally, causing a major factor. The PF advised the PNF to stand by on the emergency brake. Both pilots concurred their belief that the brake energy limits had been exceeded. With this the PF communicated that he was going to taxi the aircraft off the runway by the last taxiway to the long-term aircraft parking area (a hard dirt packed area familiar to both pilots). This decision came after both pilots believed that the aircraft could not be stopped within the remaining runway. This decision seemed best to the PNF, it would avoid taxi and runway lights as well as appeared to be a safer area, no trees and level surface. The aircraft came to a full stop as planned with very little braking required. The aircraft was inspected and no damage was observed. However, the brakes were very hot as expected. After filing a local police report and allowing the brakes to cool, with the PNF now at the controls, the aircraft was taxied onto the tarmac. Further inspections were done and no damage had occurred. Further time elapsed to allow the brakes to cool, then a final inspection was completed. The aircraft was put through a series of normal and rapid taxi brake checks as well as engine and thrust reverser checks, all normal. After satisfactory checks had been completed the remainder of our trip was normal, 5 takeoffs and lndgs and approximately 4 hours of flying with the PNF now as the PF (PIC). Factors: hot day, heavy aircraft, long landing, fast vref, old aircraft. Excellent communications between pilots during landing roll. I believe the brake energy limits were exceeded along with a long landing.

Title: LTT HAS POOR BRAKING ON LNDG ROLL. ELECTS TO ROLL ONTO TAXIWAY OF HARD PACK DIRT VERSUS RUN OFF END OF RWY.
Narrative: AN E LNDG IN VFR CONDITIONS WITH AN ESTIMATED WIND FROM 090 AT 10 KTS, HOT DAY APPROX 90 DEGS F, HVY ACFT BUT UNDER MAX LNDG WT, RESULTING IN A HIGH REF AND APPROX 3100 FT LNDG ROLL WITH A RWY OF 5000 FT. TOUCHDOWN OCCURRED APPROX 1400 FT DOWN THE RWY. BRAKES, SPOILERS AND THRUST REVERSERS WERE USED IN A VERY TIMELY MANNER. HOWEVER, DECELERATION WAS SLOWER THAN NORMAL. THE PNF APPLIED BRAKES NOTING THE L BRAKE WAS NOT OPERATING NORMALLY, CAUSING A MAJOR FACTOR. THE PF ADVISED THE PNF TO STAND BY ON THE EMER BRAKE. BOTH PLTS CONCURRED THEIR BELIEF THAT THE BRAKE ENERGY LIMITS HAD BEEN EXCEEDED. WITH THIS THE PF COMMUNICATED THAT HE WAS GOING TO TAXI THE ACFT OFF THE RWY BY THE LAST TAXIWAY TO THE LONG-TERM ACFT PARKING AREA (A HARD DIRT PACKED AREA FAMILIAR TO BOTH PLTS). THIS DECISION CAME AFTER BOTH PLTS BELIEVED THAT THE ACFT COULD NOT BE STOPPED WITHIN THE REMAINING RWY. THIS DECISION SEEMED BEST TO THE PNF, IT WOULD AVOID TAXI AND RWY LIGHTS AS WELL AS APPEARED TO BE A SAFER AREA, NO TREES AND LEVEL SURFACE. THE ACFT CAME TO A FULL STOP AS PLANNED WITH VERY LITTLE BRAKING REQUIRED. THE ACFT WAS INSPECTED AND NO DAMAGE WAS OBSERVED. HOWEVER, THE BRAKES WERE VERY HOT AS EXPECTED. AFTER FILING A LCL POLICE RPT AND ALLOWING THE BRAKES TO COOL, WITH THE PNF NOW AT THE CTLS, THE ACFT WAS TAXIED ONTO THE TARMAC. FURTHER INSPECTIONS WERE DONE AND NO DAMAGE HAD OCCURRED. FURTHER TIME ELAPSED TO ALLOW THE BRAKES TO COOL, THEN A FINAL INSPECTION WAS COMPLETED. THE ACFT WAS PUT THROUGH A SERIES OF NORMAL AND RAPID TAXI BRAKE CHKS AS WELL AS ENG AND THRUST REVERSER CHKS, ALL NORMAL. AFTER SATISFACTORY CHKS HAD BEEN COMPLETED THE REMAINDER OF OUR TRIP WAS NORMAL, 5 TKOFS AND LNDGS AND APPROX 4 HRS OF FLYING WITH THE PNF NOW AS THE PF (PIC). FACTORS: HOT DAY, HVY ACFT, LONG LNDG, FAST VREF, OLD ACFT. EXCELLENT COMS BTWN PLTS DURING LNDG ROLL. I BELIEVE THE BRAKE ENERGY LIMITS WERE EXCEEDED ALONG WITH A LONG LNDG.
