Narrative:

Following landing on runway 35R, I used reverse thrust and then went for some brakes to take a high speed exit. When pushing over on both brake pedals, they bottomed out. I didn't have full directional control and the right main tire went off the edge of the runway surface. I managed to regain good footing for the right main and continued taxiing in to the FBO. We had just had our brakes relined the previous day. This was followed by the high speed taxi brake checks to get the pads seated. We have no further explanations as to what caused it. From this point on, I plan on checking brakes to see if there is brake pedal pressure as a part of my landing checks.

FROM THIS POINT ON, I PLAN ON CHKING BRAKES TO SEE IF THERE IS BRAKE PEDAL PRESSURE AS A PART OF MY LNDG CHKS.
