If either light is on and braking feels different than normal, do not continue driving. Request service where the vehicle is safely parked.
What the Red Brake Warning Light Means
The red brake warning light monitors: parking brake engagement (most common trigger), brake fluid level, pad wear sensors, and brake system pressure. Because it connects to the primary braking system, a red brake light that's on after the parking brake is released warrants investigation. Common causes: low fluid from worn pads, a brake system fault, or a hydraulic pressure issue. See our page on driving with brake warning light on for detailed guidance.
What the ABS Warning Light Means
The yellow or amber ABS light indicates the anti-lock braking system has detected a fault. ABS is a safety layer on top of the base brake system. When ABS light is on alone, your base braking typically still functions. What you lose is ABS protection in emergency stops or slippery conditions. The ABS system should be diagnosed and repaired. See our page on driving with ABS light on for more detail.
What Happens When Both Lights Are On
Both the ABS light and brake warning light illuminated simultaneously is the most serious combination. This can indicate a condition affecting the overall brake system — not just the ABS layer. Treat this as an urgent situation. Get the vehicle inspected before driving further if possible. One Day Brakes can come to your location for a mobile brake inspection.
Can You Drive With Each Light On?
ABS light alone: Usually okay for short distances — base braking typically intact. Get it diagnosed promptly. Brake warning light alone: Depends on the cause. Parking brake — release it and confirm light clears. Low fluid or system fault — diagnose before continued driving. Both lights: Treat as urgent — inspect before further driving if possible.

Frequently Asked Questions
What does the red brake warning light mean?
It indicates a problem with the primary braking system — commonly low brake fluid, a pressure fault, pad sensors, or the parking brake being engaged.
What does the ABS light mean?
It means the anti-lock braking system has detected a fault. Regular braking typically still works, but ABS may not activate in an emergency stop.
Which light is more serious — ABS or brake warning?
The red brake warning light is generally more immediately serious because it relates to the primary braking system. ABS is a safety feature on top of the base system.
What if both lights are on at the same time?
Both on together is more serious — it can indicate a condition affecting the overall brake system. Get the vehicle inspected before driving further if possible.
Does the ABS light come on when brake fluid is low?
It can, on some vehicles. Low brake fluid can trigger both the brake warning light and the ABS light depending on the system.
Can I reset the ABS or brake warning light myself?
You can clear the code, but if the underlying issue isn't fixed, the light will return. Fix the cause, not the symptom.
Will One Day Brakes help me diagnose a warning light?
We can inspect the brake system components and advise on what we find. For full ABS module diagnostics, additional scanning tools may be needed.
How do I know which light is on if I'm not sure?
The brake warning light is typically red and may show 'BRAKE.' The ABS light is typically yellow or amber and shows 'ABS.' Both are distinct symbols on your instrument cluster.
