Our E-brake is attached to a drum brake in the back, not the discs brakes like most cars, I don't know if its strong enough to lock the wheels up, but it might be. I was scared I might break it
I've found it easy to just trail off the brake coming into a corner. The more braking force, the less the car understeers. Its the only way to get the damn thing to turn with stock 97 suspension....
