What is the reason for the car not stopping and sliding forward when braking?

[DominicLynn]

Braking not stopping and sliding forward is caused by the transmission structure. Transmission: After running the car, the AT transmission turbine will enter the gearbox oil to push, achieving the purpose of shifting by squeezing and integrating different friction plates. The turbine is the first device for engine power transmission. Every time the car stops, because the turbine is a hydraulic mechanism with certain inertia inside, it will continue to rotate. Reason for sliding: Automatic transmission cars only have one brake pedal and accelerator, and the characteristics of brake pedals vary among different cars. Some cars require deep pressing of the brake pedal to stop, while others stop with just a light press. This leads to the problem described, which occurs because the depth of pressing the brake pedal is insufficient, and the car has not yet fully braked, still being in a state of sliding forward.

I've experienced a few instances where the brakes failed to stop the car, causing it to slide forward, which was truly terrifying. The most common reason is severely worn brake pads. Over time, the surface becomes smooth or too thin, reducing friction and making it hard to stop the car. There's also the issue of brake fluid—if the level is low or air gets into the system, the hydraulic system fails, making the brake pedal feel soft. Additionally, slippery conditions like wet roads or snow can cause skidding, and severely worn tires reduce grip. Once, while driving in the rain, my brakes suddenly failed, and the car slid for a distance—luckily, no one was around. Remember to check your brake system regularly, at least every six months, inspecting brake pad thickness and fluid condition to avoid major issues. Don’t forget, a faulty brake booster can also reduce braking effectiveness, making the pedal feel stiff—test the pedal a few times before driving. Safety first—never take it lightly.

After driving for so many years, encountering brake failure is quite frightening. I usually first consider if it's a tire issue. Worn-out tires with shallow treads have weak grip in rainy weather, making the car prone to skidding. Next, it could be a malfunction in the ABS anti-lock braking system. Normally, it should adjust the braking force, but if the electronic sensors fail, the system becomes ineffective, and the car won't stop. Or, the brake discs might be rusted or warped, causing uneven friction. I still remember one time when the brake fluid leaked, causing the entire system to lose pressure, and the pedal had no response when pressed. Preventive measures include checking tire pressure and tread depth monthly and repairing immediately when the ABS light comes on. Young people often overlook these, but early detection saves a lot of money. Maintain good car condition, don't wait until an accident happens to take action, and always have the technician inspect the brake system during every maintenance check.

Brake failure causing forward sliding mostly stems from a few points. Worn-out brake pads lacking friction is the most common issue; thin pads become ineffective. Insufficient or dirty brake fluid affects hydraulic transmission, resulting in insufficient force. Severe tire wear leads to poor grip, especially noticeable on wet or slippery roads. Problems with the power assist system can also make the brakes stiff and hard to stop. Regular checks of these components can prevent issues before they occur.

Brake failure poses significant hazards, which is why I always emphasize prevention. The main causes include aging and wear of brake pads, hydraulic failure due to fluid leakage, or slippery roads causing tire skidding. Neglecting maintenance can worsen these issues, so it’s essential to regularly replace brake pads, check fluid levels, and inspect tire conditions. I’ve witnessed such accidents on highways, often rooted in long-term lack of maintenance. Develop the habit of testing brake pedal responsiveness monthly and seek immediate repairs if abnormalities are detected to avoid risks.

The braking system of Hyundai vehicles is quite complex, and faults can arise from multiple factors. Worn brake pads reduce friction, making the car prone to slipping. Fluid issues, such as air contamination, can cause hydraulic failure, while a faulty booster makes the pedal harder to press. If the ABS electronic system's sensors are damaged, brake modulation becomes inaccurate. Worn tires or insufficient tire pressure reduce grip effectiveness. I always pay attention to these details and feel that the braking response returns to precision after replacing new components.
