Narrative:

Upon landing at 100 knots; the pilot flying applied the brakes. When the aircraft decelerated to about 80 knots the plane started to vibrate excessively. First officer commented that there was something 'not right' with the brake that was replaced the previous night. First officer released the brake pressure and he allowed the plane to roll until he could turn the aircraft onto the taxiway below 60K. We finally isolated the problem to the left brake. While taxiing we did not apply any pressure to the left brake; but we both noticed that it was taking 30 % N1 to keep the plane moving. When we turned into the FBO ramp; the linemen noticed that there was smoke and a small fire coming from the left brake assembly. The lineman signaled that the left brake was on fire; so he directed an over wing emergency evacuation. As I was moving to the exit; I noticed black smoke coming up from the bottom of the aircraft. The passengers went out first; and then myself followed by the flight attendant and then the other pilot. While we were evacuating the plane; the linemen grabbed a fire extinguisher and watched the brake assembly until everyone was clear of the plane. After the smoke stopped; we noticed that it was the #2 brake assembly that was charred with black residue and the tire was flat. Fire and rescue was not called.
