Causes can range from an electrical malfunction to something as simple as a dirty wheel speed sensor. Problems with the antilock brake system can trigger both the brake warning light and ABS light (if it has one) to turn on. Most vehicles equipped with an antilock brake system (ABS) have an ABS brake warning light. Once the brake pads are too worn, this sensor wire contacts the rotor and forces the brake light (or brake pad warning light) to light up. This can also be down to the sensor wire on your brake pads. Worn brake pads can also cause a drop in brake fluid level as the caliper pistons have to reach further to contact the rotor, which can also trigger your brake warning light. Low brake fluid levels can be a major cause for concern as it can indicate a brake fluid leak which will need addressing ASAP. If levels are below the minimum threshold, the sensor will trigger the brake light to illuminate. Low Brake Fluid LevelsĪ sensor in the brake master cylinder monitors the brake fluid level in the system.
