Brake fluid is leaking Inspection $79.99 - $89.99 Get a Quote

Hi There, This may suggest that your brake pads are worn and due to be replaced or that you have a leak somewhere in your brake hydraulic system. The brake reservoir has a sensor inside that detects when the brake fluid reaches a certain point which generally indicates that it is time to replace the pads. As your pads wear thinner and thinner over time, the brake lines require more and more brake fluid to maintain the same amount of hydraulic pressure in the brake lines. As a result, the brake fluid level sensor will trigger a warning light indicating that the brake fluid level is low.

Your car is equipped with wheel speed sensors at each of the four wheels which monitor wheel speed while relaying this information constantly to the ABS and traction control system which are controlled by the car’s ECU. When the ECU senses an abnormal speed given specific conditions, it engages the ABS or traction control as needed to control the vehicle properly and safely. Occasionally, these sensors can fail or become faulty working intermittently sending inaccurate signals to the ECU. When this happens, you may experience the symptoms you have described. The ABS or traction control system may be inadvertently activated by these false or inaccurate signals. I would suggest having a professional from Your Mechanic come to your to diagnose ad inspect your vehicle.
