What Causes Heavy Brakes and Failure to Start?

[SanBrody]

It may be because the driver pressed the brake pedal several times after turning off the engine, causing the vacuum in the brake booster to disappear. Without the booster's assistance, the brake pedal becomes harder to press. Additionally, the booster pump does not operate when the engine is off. Below are some braking precautions: 1. At low speeds, you can perform emergency braking by fully pressing the brake pedal if an unexpected event occurs ahead. However, avoid doing this at high speeds to prevent the vehicle from skidding or rolling over. 2. During normal driving conditions, apply gradual braking by pressing the clutch pedal while releasing the accelerator, then shift to a lower gear. Once the speed decreases, release the clutch pedal and press the brake pedal until the vehicle stops. 3. On long downhill slopes in mountainous areas or during continuous braking that generates high temperatures, intermittent braking—alternately pressing and releasing the brake pedal—can effectively prevent the braking system from overheating.
