Red brake warning light staying on? See possible brake-fluid, parking-brake and hydraulic-system causes and when the vehicle should not be driven.
Treat as safety-critical
A red brake warning can be as simple as the parking brake still being applied, but it can also indicate low brake fluid or a braking-system fault. Because braking is safety-critical, do not ignore a warning that remains on after the parking brake is fully released.
If the warning stays on with the parking brake released and the pedal feels soft, sinks further than normal, braking has changed or fluid appears to be leaking, stop somewhere safe and arrange recovery or professional inspection.
Fluid level can fall gradually as pads wear, but a significant or sudden drop can also indicate a leak. Simply topping up fluid without understanding why the level fell can hide an important fault.
Normal pedal feel does not prove the warning is harmless. Check the handbook for the exact symbol and arrange inspection if the light remains on. Some vehicles use separate warnings for parking brake, fluid level, electronic parking brake and brake-pad wear.
A technician may check fluid level and condition, leaks, pad and disc wear, hydraulic components, parking-brake operation and stored fault codes on vehicles with electronically controlled braking systems.
Photograph the dashboard and AutoAid can help identify the symbol, ask follow-up questions and explain likely next steps.
