Brake Warning Light or ABS Light On? What It Means

Cars have two brake-related warning lights. The red BRAKE light usually means the parking brake is on, the brake fluid is low, or there's a problem in the hydraulic system. The amber ABS light means the anti-lock system has a fault, while normal braking should still work.

If the red brake light stays on with the parking brake fully released, or the pedal feels soft, sinks toward the floor, or the car takes longer to stop, don't keep driving. Have the car towed or inspected before driving further.

Quick checks you can do safely

Make sure the parking brake is fully released. This is the most common reason the red light is on.
With the engine off, look at the brake fluid reservoir under the hood and check the level against the MIN and MAX marks.
Notice whether the red light, the ABS light, or both are on. Both together needs attention right away.
Pay attention to how the pedal feels. A soft or sinking pedal points to a hydraulic problem.

What's usually behind it

A parking brake that isn't fully released, or a faulty parking brake switch
Low brake fluid from worn brake pads or a leak
A faulty wheel speed sensor or damaged sensor wiring (ABS light)
A failing ABS module or pump

QUESTIONS

Brake Warning Light or ABS Light On: common questions

Is it safe to drive with the ABS light on?

Normal braking usually still works, but the anti-lock system may not help in a hard stop or on a slippery road. Drive carefully and have it checked soon. If the red brake light is on too, stop driving.

Can I just add brake fluid?

Topping it up can get you to the shop, but brake fluid doesn't get used up. A low level usually means worn pads or a leak, so it's worth having the brakes inspected rather than only adding fluid.
