Why does the car fail to start due to brake failure?

The reasons for failing to start due to brake failure are as follows: 1. Brake shoe failure, abnormal or irregular wear; brake pads need to be replaced; 2. Oil leakage (brake fluid), insufficient brake fluid; simply replace the brake fluid; 3. ABS system failure, abnormal wheel speed sensor or wiring; check if the battery is low on power and charge it in time; 4. Spark plug failure, leading to an increased ignition gap, causing failure to start. Simply replace the spark plug. Additional information: 1. ABS system failure, abnormal wheel speed sensor or wiring, brake cylinder failure, such as fluid leakage or poor return. This situation indicates a parking brake system failure. It is recommended to contact professional maintenance personnel at a 4S shop to use a computer to check the specific fault content and then carry out targeted repairs. 2. If the vehicle's brakes fail, the vehicle is not allowed to drive. After the vehicle's brakes fail, the vehicle's braking system will be ineffective, and driving a vehicle without a braking system on the road is very dangerous. After the vehicle's braking system fails, the vehicle must be sent for repair immediately, and a tow truck can be used.
Last time my car had this issue - with automatic transmission models, you need to step on the brake to start the engine. But that time the brake light switch was faulty, so the signal couldn't reach the engine control module, and the car simply refused to start. I tried multiple times, but stepping on the brake didn't help - possibly a blown fuse or poor wiring contact. This situation commonly occurs in older vehicles or humid environments where sensors are prone to failure. Later at the repair shop, they found the braking circuit is interconnected with the starting system - one component fails and the whole system goes down. I recommend everyone regularly check brake response and keep the system clean. Don't force attempts on the road to avoid draining the battery and compromising safe travel. Getting professional mechanics to solve it promptly is the best approach - saves both time and hassle.
