Understanding Your BMW’s Brake Warning Light
The brake warning light, typically a red exclamation mark or the word “BRAKE,” illuminates for several reasons. It could signal worn brake pads, low brake fluid, a malfunctioning sensor, or an issue with the ABS system. Ignoring this warning can compromise your safety and lead to costly repairs. It’s crucial to address it promptly.

Common Causes and Solutions
Worn Brake Pads
This is the most frequent cause. If your pads are worn down, replacing them is the only solution. After replacing them, the warning light should reset automatically. However, in some cases, you might need to manually reset it. bmw 1 series brake fluid warning light reset
Low Brake Fluid
Low brake fluid can significantly reduce braking power. Top up the fluid to the recommended level. If the light persists, there may be a leak in the system requiring professional attention.
Faulty Sensors
A malfunctioning brake pad wear sensor or ABS sensor can trigger the warning light even if there’s nothing wrong with the brakes. Diagnosing this requires specialized equipment, so a visit to a mechanic is recommended.
