Can the car brake effectively when stalling on a slope?

When a car stalls on a slope, pressing the brake immediately can effectively stop the car, followed by promptly engaging the handbrake. Pressing the brake immediately: If the car suddenly stalls on a slope, the first step is to press the brake to prevent rolling backward, and then attempt to restart the engine. This is because the car relies on brake fluid to activate the brakes. The first press of the brake will still work when the car is in neutral after stalling, but afterward, it becomes difficult to press the brake pedal, and the steering wheel also becomes hard to turn. Starting on a slope: It is best to use both the foot brake and handbrake when starting on a slope. The required throttle varies with different slopes. If you follow too closely, the car might lurch forward. Engaging the handbrake and releasing it when starting makes the process easier and safer.
When the car stalled on a hill, I immediately hit the brakes and found they still worked, but required much more force than usual. That steep slope almost caused a rollback, which really scared me. It turns out that when the engine stalls, the vacuum booster fails too, leaving the braking system relying solely on the hydraulic pressure from foot pedal force. Although the basic braking function remains, it becomes significantly weaker and less efficient. I later learned that with manual transmission cars, stalling might not lock the gears, making rollbacks more likely. My advice is to pull the handbrake or shift into reverse immediately after stalling to help secure the car. Now, I always pay extra attention to checking the brake booster system during routine maintenance to avoid failures in critical moments. For safer driving, it's best to avoid frequent starts and stops on hills and ensure the engine is in good condition to prevent unnecessary trouble. This experience taught me to always assess road conditions before climbing hills, reducing risks significantly.
