Engine stumbles when applying the brakes

Hi,

If it only happens when you come to a complete stop, I need to know if it has an automatic transmission. If it stumbles anytime you apply the brake regardless of speed, it sounds like an engine vacuum leak that can be directly related to the power brake vacuum booster.

Here is a link that explains how to find a vacuum leak:

I attached a pic of the booster below and circled the vacuum hose. Check it for damage and make sure it is properly attached.

Let me know.

Car cranks up and idles and then shuts off.

Are you able to keep it running if you keep pressing the gas or is it only when you apply the brakes?

Let me know.
