Warning Light on Dashboard

The most common way to know when to reset the brake fluid light on BMW is through the warning light that appears on the dashboard. This indicator light shows up as a circle with an exclamation point in the middle. If you see this light, it means that there might be an issue with your brake system or a low level of brake fluid.

If the light comes up while driving, experts advise that you pull over and check whether something is wrong with the brakes or if it’s only due to low brake fluid levels. However, resetting the brake fluid light won’t fix the problem completely; it will only silence the notification, so seeking professional help for repairs afterward is necessary.

Low Brake Fluid Levels

If the brake fluid level is low, it can also trigger the brake fluid light. The brake fluid functions are to transfer force from the master cylinder onto the brake calipers or shoes during braking, lubricate all hydraulic parts and prevent oxidation and rust. If the brake fluid depletes quickly, the result could lead to poor braking performance. According to Mechanic Base “A significant sign of depleted brake fluid is the worn-out color.” Mechanics recommend checking the brake fluid at least once every two years but the life span depends on the mileage created by the vehicle per year. As such, if the brake fluid looks brown, murky, or black when checked, flushing or topping it off with new brake fluids is vital.

“When the boiling point of brake fluid drops too low, vapor bubbles may form in the brake lines, reducing brake efficiency just when you need it the most.” -Eric Evarts, Consumer Reports

Preventing any damages that may occur due to low brake fluid levels, it’s recommended that you take your BMW for regular maintenance checks and servicing. Additionally, if the dashboard shows an illuminated brake light, attend to the issue promptly because it could be indicative of a fault in the brake system beyond depleted brake fluid.
