Judging from your description, and from what I can tell reading the data, it looks like the brake application might have been just barely enough to upset the car's balance, causing a slight rotation that you countered a little late, then it went haywire. The tire's slide might have been subtle enough that you didn't really feel it at first.

You can see where you hit the brake, there's a slight amount of lateral accel right before you release the pedal at 0:54 where a (assumed RH) slide begins, then more lateral accel with minimal steer input through 0:56, this is where the slide builds steam and becomes difficult to overcome. About halfway through the RH slide at 0:56 you begin to countersteer and slightly over correct (or the car's inertia whips back) and you snap back to slide LH at 0:58. 0:58 is where it appears you went offroad, and 0:59 started panic braking even though it didn't do anything. Slide for 2 more seconds, then hit the wall at 1:01.

Video would be definitive, but this is the best I can tell from your limited description and the data...
