The fact that the motor stalls when you hit the brakes makes me think that the brake booster is bad and the internal diaphragm is shot, causing a HUGE vacuum leak. Disconnect the vacuum line going to the brake booster and suck on it. It should hold perfect vacuum.

 

If your idle is too high, try reducing it. I read somewhere that a high idle can produce a stalling effect while braking.
