Braking Causes Car to Cut Out – Reasons

Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine.

What causes a car's electrical system to suddenly stop working?

Loose battery connections can cause an electrical system to “shut down” and then start working again, as can bad fusible links, so the connections between the battery and the rest of the electric system should be checked out thoroughly before anything else.

Why does my engine go off when I brake?

Most likely you have a problem with your IAC (idle air control) valve. They get gummed up with carbon deposits and stick. One other possibility is your power brake booster has a vacuum leak. ... This can easily be tested for by pinching off the hose connected to the brake booster and pressing on the brake pedal.

Why does my radio cut out when I brake?

The alternator is what provides the electric to your car whilst it is running. If it is not functioning correctly then it will not have the power to run everything on the car, possibly why you say the stereo dies when you brake. The additional draw of power to the brake lights could bring the voltage down.

How do I stop my brakes from stalling?

How do I know if I have an electrical problem in my car?

The most common sign of electrical issues within the vehicle is a clicking noise upon attempted ignition. When the clicking occurs, the car doesn't have enough current flow in its electrical system to start the engine. Usually, this means that the car's battery has lost its charge or is at the end of its useful life.

What is the best way to diagnose an electrical problem?

Check the ground connection with your ohmmeter. If the ground connection is good, the fault is inside the component. If there is no voltage in the "hot" wire to the component, then the problem is in the wiring. Trace back through the fuse panel (or relay or circuit breaker) until you find voltage.

Why does my new car shut off when I stop?

The concept of the stop-start system is simple. It automatically shuts off the engine when the vehicle is at rest to cut fuel use and eliminate idle emissions.

How do you test a brake booster?

Inspect the vacuum hose to the booster for kinks, cracks or other damage. Check vacuum at idle with a vacuum gauge. To test booster function once the reserve is depleted, hold moderate pressure on the brake pedal and start the engine. If the booster is working properly, the pedal will drop slightly.
