Truck stalling and brake problem

Have an 89 150. Stalls at low idle when turning wheel. Also no brakes. New calipers, new fluid, bled brakes. Booster not leaking, master cylinder not leaking. Pedal goes to floor unless you pump it. Also sometimes idle jumps high to low in park. Please help...need this truck going for a service truck.

Are you leaking power steering fluid along the hose? There is a switch, for lack of a better word, that screws into the hose that when the wheels are turned will send a signal to raise the idle. They will start leaking fluid and go bad.

Did your brake pedal act normal before the brake work? Are the bleeder valves on your new calipers toward the top? If the bleeder valves aren't toward the top you probably got them on the wrong sides, drivers side on passenger side and visa versa. Just a thought.

did you check your rear wheel cylinders, for leaks, did you start on passenger rear, then driver rear, then passenger front, then driver front, when you bled them
