What it means
This warning can mean brake fluid is low, though the same symbol may also indicate an applied parking brake or another brake-system problem. Red signals a potentially serious condition, but the exact symbol and behaviour vary by manufacturer; check the owner's manual.
What the symbol looks like: An exclamation mark inside a circle, often enclosed by curved brackets, indicating a brake warning.
Why it comes on
- Brake fluid is low
- A brake hydraulic line, hose, or component is leaking
- Brake pads are worn, lowering the fluid level in the reservoir
- A fluid-level sensor or its wiring has failed
What to do
- Stop safely and check that the parking brake is fully released.
- If the warning remains, do not continue driving.
- Look for visible fluid leaks without going beneath the vehicle.
- Arrange professional inspection or recovery; do not simply top up and ignore the warning.
Can I keep driving?
Do not drive with a persistent low-brake-fluid warning, a leak, or any change in braking. A loss of hydraulic pressure can reduce braking ability or cause brake failure.
Symbols and colours differ between makes and models. Your owner’s manual shows the exact lights of your car.
