Hitting the brake was likely your fatal error. It happened to me too with the same end result (although I didn't exactly have a choice, it was brake and possibly avoid a crash or crash.) However it was likely initiated as previously stated by the shocks.
Don't give it more than an armful of lock when steering into the skid. And be ready to apply some small steering input back again to slow the front end down when it comes out or you'll likely find yourself spinning the other way.
However the above advice is a lot harder than it sounds and it's worth practicing getting the arse out in a safe space.
All the advanced driftin' techniques aside, the main thing is that you didn't get hurt and the car isn't too badly off.
The master has spoken.
