My mom had me drive her car this Sunday to check something out. Apparently when you have the wheel turned all the way to the right while moving (slow speeds, in a parking lot) it seems to kick in the ABS pump for a couple of seconds, there is a faint pulsation in the break pedal. It's an '07 Pontiac Torrent

There's your problem

There's your problem

ok other than that...what could be going on

bad wheel speed sensor.
steering angle sensor. the LS has a steering angle sensor that affects things under hard turning.
abs brain.
and so on. most cars can do an abs self test.
