What is the brake fluid insufficient warning light?

[River]

When the brake fluid is insufficient, the warning light shows a bracket with a circle inside, and there is an exclamation mark in the circle. Brake fluid, also known as hydraulic brake fluid, is the hydraulic medium in the automobile braking system. Since liquid cannot be compressed, the pressure output from the master cylinder is directly transmitted to the wheel cylinders through the brake fluid. Brake fluid can be categorized into silicone-based and non-silicone-based types. The phenomena caused by insufficient brake fluid include: Increased temperature in the braking system, vapor filling the pipelines in localized areas, leading to vapor lock and brake failure; The dashboard will issue a warning. Brake fluid is the liquid medium that transmits braking pressure in hydraulic braking systems and is used in vehicles equipped with hydraulic braking systems. The reasons for insufficient brake fluid are: Brake fluid pipe rupture; Damage to metal or rubber components in the braking system; Loose or damaged pipe screws. Car owners should pay attention to the following when using brake fluid: Do not mix different types or brands of brake fluid. Due to differences in formulation, mixing brake fluids can reduce the performance indicators of the brake fluid. If the brake fluid absorbs moisture or contains impurities, it should be replaced or filtered promptly. Otherwise, it may cause insufficient braking pressure and affect braking performance. This is particularly important in the generally humid climate of southern China. Under normal driving conditions, if the vehicle has traveled 40,000 kilometers or the brake fluid has been in continuous use for more than 2 years, the brake fluid may deteriorate due to prolonged use and should be replaced promptly. During normal driving, if the braking feels inconsistent (sometimes light, sometimes heavy), consider inspecting or replacing the brake fluid promptly. If the vehicle's braking is uneven (pulling to one side), choose a higher-quality brake fluid for replacement and replace the rubber cups at the same time.

I remember during a long-distance trip last time, a red light suddenly lit up on the dashboard, shaped like a small oil can with an inverted triangle. That was the low brake fluid warning light. Brake fluid, commonly known as brake oil, is essential for the braking system. If it's low, the braking system feels like it's running out of fuel—the pedal becomes soft, and the car may not stop steadily, especially in rainy weather or on downhill slopes, which can be particularly dangerous. I pulled over immediately, popped the hood, and located the transparent plastic reservoir. The fluid level was already below the minimum line. It was likely due to consumption or a minor leak. I quickly topped it up with compatible DOT4 brake fluid at a roadside repair shop, and the light went off. Since then, I've made it a habit to check the fluid level every few weeks, keeping it between the min and max marks. Safety is no small matter—when this light comes on, it should be prioritized. Don't wait until an accident happens to regret it.

Over the years I've been driving, the brake fluid warning light has come on a few times. That light is usually designed to be conspicuous, in yellow or red, shaped like a dripping droplet, alerting you to possible low brake fluid levels. Brake fluid plays a crucial role in the braking system, functioning similarly to hydraulic transmission for power transfer. If the fluid level is low, you'll feel the pedal sink when braking, with delayed brake response. Once the light illuminates, immediately reduce speed and pull over to a safe spot. After the system cools, check the fluid level in the reservoir under the hood. If it's below the marked line, top up with fresh fluid - check your owner's manual for the correct specification (DOT 3 or 4, don't mix them up). If the issue recurs frequently, there might be a leak requiring a technician to inspect pipe seals. Regular maintenance including fluid changes significantly reduces unexpected failures, and staying vigilant while driving benefits everyone.

When the brake fluid low indicator lights up, that red warning icon on the dashboard usually looks like a bucket pouring water to indicate low fluid level. Insufficient brake fluid will cause sluggish braking response, significantly increasing driving risks. When I encountered this situation, I safely pulled over to check the fluid reservoir level and topped it up to ensure safety. If the warning light keeps coming on, you should inspect for leaks or have the system serviced.
