Wait what? Maybe you should ask yourself is you trying to do drifts, in a fwd car, stuffed the handbrake causing your wife to think she's at fault? And if you knew the handbrake wasn't holding do you think it's a priority? I made the mistake for leaving a handbrake to be adjusted at the next service and same thing brother borrowed the car, rolled down the street.. I adjusted it the next morning If its adjusted correctly not much more you can do, is your handbrake apart of the rear brakes or does it have shoes in the rotors (separate to the rear disc brakes) I've seen (if it's shoes) the inside diameter worn excessively in the disc so the shoes down work good no matter how good the adjustment is.
