No one likes seeing their car’s warning lights on the dashboard turn on — it always means something is wrong with the car, and when things go wrong with a vehicle, it tends to get expensive.
Your car’s brake light could indicate some different things. What causes the brake warning light to illuminate, and what should you do if you see it?
There are some instances where you can check it out after your trip, and other times when you shouldn’t drive it anymore at all. So how do you tell the difference?
Why is The Brake Light On?
First, what causes the brake warning light on your dash to turn on? Depending on your car, it could indicate some different problems, including but not limited to:
- Parking brake engaged: You left the parking brake on when you were trying to drive. This is of course the simplest and easiest to fix problem on the list, but if you don’t usually use your parking brake it can be easy to forget that it’s own.
- Brake fluid levels: If brake fluid levels are low, in some cars, it can trigger the brake warning light. Your manual will tell you if that’s the case.
- ABS (Anti-Lock Brakes) problems: Most modern cars have a separate ABS light that comes on when there’s a problem with that system, but some cars still trigger the brake warning light instead.
- Brake light bulbs: Newer cars may light up the brake light if one or more of your bulbs has gone out.
The best way to get the most accurate answer is to check your car’s owner’s manual. This book will have a detailed list of your car’s warning lights and what each one means. Sometimes you can find out what to do without even leaving the seat of your car.
What To Do When The Brake Light is On?
What should you do if your brake light comes on? First, check your owner’s manual. Find out precisely what the brake light means for your particular make and model to remove most of our troubleshooting steps.
In case you don’t have an owner’s manual or don’t want to dig it out of your glove compartment, you can always look online. Most car manuals can be found with a quick Google search, giving you everything you need to know.
Here are are some quick troubleshooting steps to follow:
- Check your parking brake: If you engaged the parking brake the last time you stopped your car and forgot about it, that could be the problem. Just shut off the parking brake, and you should be good to go.
- Put the car in park, pop the hood and check the brake fluid levels: If the levels are low, top the brake fluid off and start the car again to see if it fixes the light.
- Consider a professional: If your car’s generic brake lights also indicate a problem with the ABS, you might want to have the system inspected by a professional. Brakes are one factor you don’t want to cut corners on — faulty brakes can be dangerous or even deadly.
- Check your brake lights: Have someone stand behind the car while you press the brakes to see if one or more of the bulbs have burned out. If they have, replace them, and the brake light should shut off.
Most of the problems that a brake light indicates are simple and easy to fix. The only time you’ll want to make sure you take a trip to your mechanic is if there’s a problem with your vehicle’s ABS.
