Bangkok: When it comes to road accidents, one of the most terrifying phrases for drivers is "brake failure." Many people may have seen information shared on social media about various causes of brake system failure. Motor Check's fact-checking center has verified the facts with Assoc. Prof. Dr. Jinda Charoenpornpanich, Chair of the Advanced Automotive and Transportation Engineering Program (International Program), Faculty of Engineering, King Mongkut's Institute of Technology Ladkrabang (KMITL), who confirmed that the shared information is "true."
According to Thai News Agency, this article delves into the eight main mechanisms and causes of brake failure, so that all vehicle owners can be vigilant and take proper preventative measures. Understanding the basics of the braking system is crucial. Most car braking systems are "hydraulic," using fluid as a medium to transmit force. When you press the brake pedal, that force is transmitted through the brake pump, increasing the pressure enough to grip the brake disc and stop the car. However, because this system uses fluid, even a single leak will dissipate all the pressure, resulting in a feeling of a spongy, light brake pedal, and the car not stopping when the brakes are pressed.
Experts have categorized the causes of brake failure as follows: a leaking brake pump, a broken brake line, leaking brake fluid lines, brake fluid overheating and deteriorating, worn brake pads, brake pad burnout, brake disc cracking, and improper braking leading to brake fade.
From all the information, it can be seen that "brake failure" does not always mean a broken brake component but rather encompasses the loss of stopping effectiveness due to various factors, including mechanical problems and issues related to driving behavior. Regularly checking the condition of the brake system, brake fluid, brake lines, and the thickness of the brake pads/brake discs is essential. Additionally, learning how to use engine braking when driving downhill and remaining calm in emergencies are crucial strategies for preventing brake failure.
