Narrative:

9/89, I was asked by our maintenance personnel to taxi our company small transport from one point of the ramp to another, about 200 yds away. As I started the taxi roll down slope on the ramp, I stepped on the brakes to make sure they were working and they held fine. As I got closer to the parking spot, I started making a left turn to make a 180 degree turn. The nose wheel tiller was very stiff. As soon as I noticed the stiffness on the nose wheel tiller, I immediately stepped on the brakes, only to find that this time there was none. As I got closer to our maintenance hangar, and unable to stop the airplane by applying brakes, I pulled both throttles into reverse thrust, trying to the get airplane stopped, but the airplane kept rolling and ran into a wooden section of our company hangar, breaking both the captain and copilot windshield.
