Engine brake to slow down, this will work in an automatic or manual. Just a down shift simple as that.
Do not slam on the brakes and turn, it won't do shit especially if you dont have abs you will plow and go straight.
There isn't any real reason to pump the brakes when you have abs, that said I still do it.
Its better to go into a corner too fast to than it is to slam on your brakes mid corner(this will unsettle it) your best bet is to correct as you go.
Awd cars if you start understeering mid corner (in snow ice etc etc) lay into the throttle and learn to steer with it it is possible.
Awd cars become especially unstable under heavy braking mid corner.
But really your best bet is to go to a completely empty parking lot loose control(within reason) and try to get it back keep practicing you will be good to go in no time.
But above all take it nice and easy with smooth movements steering input braking accelerating. And don't tailgate anyone.
