Why does my car shut off when pressing on brakes

You need to replace the brake light switch its mounted up under the breake pedal. Very easy to replaced its always held by a clip or screw type bracket.

SOURCE: shutting off

Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Try checking around the the brake pedal, check for the connection that goes from the alarm to the brake switch. Some times they become loose if its not a proper connection .

SOURCE: Problems 1. My brake lights stays

Hi, has someone recently installed something in the car or otherwise messed with the wiring? If not, is your ABS light on? If not either, I would say your hazard switch has gone bad.
