Chevy Truck Question

I have a 1992 chevy sportside silverado with a 350. Recently it has started stalling out whenver you hit the brakes. It cranks fine, and idles, and you can even stop 1 or 2 times before it starts to die. Any suggestions?
There may be a leak in your car's vaccuum boosted power brake system. A drop in engine manifold vaccuum could cause a drop in engine RPM and produce results like you're seeing. Have it checked out by a mechanic that you trust in your area. It could be a safety issue.
There might be the problem in the fuel pump or in the filter due to which all is happening try to replace or clean it to solve the problem.
