When the brakes suddenly fail on a downhill slope, the method that should not be used is pulling the handbrake to slow down. Below are the specific reasons for brake system failure: 1. When the brake system warning light is on, it is highly likely that the brake system has malfunctioned. 2. It may be due to low brake fluid level. Brake fluid plays a crucial role in the car's braking system. When the driver presses the brake pedal, the force applied is transmitted by the piston in the master cylinder through the brake fluid to the brake calipers at each wheel, causing the brake pads to contact the wheels and stop the vehicle. A lack of brake fluid is often accompanied by significantly reduced braking power, and in severe cases, a complete loss of braking force. This situation can be resolved by promptly replenishing the brake fluid.
I once experienced brake failure while driving on mountain roads, and the most dangerous thing to do is coasting in neutral. Many beginners think shifting to neutral saves fuel, but when going downhill, without the engine's drag, the car will accelerate uncontrollably, and the steering wheel becomes heavier, making it impossible to maintain control. Some panic and turn off the engine entirely, which completely disables power steering, making it impossible to steer through curves. Another deadly mistake is yanking the handbrake, especially in the rain, which can lock the rear wheels and cause the car to spin out—I've seen a car flip into a ditch this way. The correct approach is to downshift and use engine braking. If that fails, gently scrape against the mountain guardrail to slow down, but above all, stay calm and never jump out of the car.
