STALLING PROBLEM

1990 Buick Regal

1990 regal Custom 3.1L, auto, 170,000 miles.

After the engine warms up if you apply the brakes its stalls. You can immediately restart the engine and it runs fine until you apply the brakes, it will stall.

I would start by checking the valve to the brake booster.(Big vaumm line) That elbow check valve should only let vacumm pull one way. Take it off and blow threw it and make sure that you can only blow air threw it in one direction. Let me know results.
