How to Check the Brake System

Check the brake fluid level. The fluid should be between the “MIN” and “MAX” marks on the reservoir.
Inspect the brake lines and hoses for any leaks or damage.
Check the brake pads and rotors for wear.
Test the brake lights to make sure they are working properly.

If the Brake System is Not the Problem

If you have checked the brake system and it is not the problem, then the next step is to check the other possible causes listed above.

Here are some tips for troubleshooting the other possible causes:

* **Faulty brake light switch:** If the brake light switch is faulty, it will not send a signal to the starter to engage. To test the brake light switch, depress the brake pedal and see if the brake lights come on. If they do not, then the switch is faulty and needs to be replaced.
* **Electrical problems:** Electrical problems can prevent the starter from getting the power it needs to engage. To troubleshoot electrical problems, check the battery terminals, starter connections, and wiring.
* **Transmission problems:** Transmission problems can also prevent the car from starting. To troubleshoot transmission problems, check the transmission fluid level and condition.
* **Starter problems:** Starter problems can prevent the engine from turning over. To troubleshoot starter problems, listen for a clicking sound when you turn the key. If you hear a clicking sound, then the starter is getting power but is not engaging.
* **Battery problems:** Battery problems can prevent the starter from getting the power it needs to engage. To troubleshoot battery problems, check the battery terminals and connections.
* **Fuel system problems:** Fuel system problems can prevent the engine from getting the fuel it needs to start. To troubleshoot fuel system problems, check the fuel level, fuel filter, and fuel pump.

If you are unable to troubleshoot the problem yourself, then you should take your car to a mechanic for diagnosis and repair.
