Narrative:
Upon landing and subsequent landing rollout I was given the instructions to do a 180 [turn] on the runway; expedite taxi to and exit at charlie taxiway; which is located approximately 2;000 ft from the [approach] end of the runway. At the same time the tower controller cleared an air carrier 737-800 on to hold position on the active runway upon which I was now back taxiing. Shortly before reaching the charlie I applied brakes and there was no response. The aircraft didn't slow down and now this 737 is straight ahead in my window getting bigger with each second.I quickly tried to establish braking going through normal and emergency procedures. Instead of continuing to barrel toward the 737 I made a split second decision to depart the runway surface and handle the situation on the shoulder of the runway which was very wide and flat. Once I departed the runway surface and no longer posed a threat to the 737 holding on the active runway I coasted to a safe stop with the nose gear resting slightly in a drainage ditch. There was no damage to any airport property on or off the runway surface nor was there any damage to my aircraft.it is my professional opinion; which includes 22 years of military experience; that had that 737 not been allowed to taxi onto the active runway while I was back-taxiing I; without any doubt; could have stopped my aircraft in the confines of the runway surface remaining.upon recovering my aircraft from the shoulder of the runway we found that we had experienced a hydraulic leak from a seal on the left landing gear due to the fact that my aircraft sat outside in freezing rain and snow the night before my flight; which I personally believe had a direct impact upon this incident. I talked with a learjet safety representative and he stated that he had experienced such occurrences with seals failing going from extreme cold to hot humid climates such as we experienced.
