There are two possible ways the AC could affect the brakes in small ways. One is via the idle air control (IAC). RAY: When a major accessory, like the air conditioner, is turned on, the car's computer signals the idle air control to boost up the idle speed. That's because the air conditioner takes a lot of power from the engine, and the boost in idle speed keeps the engine from stalling and running rough when you're stopped at idle.

It's the pump. It drives off an auxilliary belt from crank. As it's not turning as freely as it should, it's using more power than normal to turn, so when on idle, then engines not producing enough power to turn it, so it stall the engine. Not sure of the Hyundai figure, but a typical aircon system can use 10-15bhp of an engines power.
