The brake lamp light illuminating on the dashboard of your Honda Accord indicates that there is a problem with the brake system. This could range from low brake fluid levels to issues with the anti-lock braking system sensors. While the car can still be driven, it is not recommended as brake performance and safety will be compromised. Acting quickly to diagnose and repair the underlying problem is crucial.
In this article, I will use my 20 years of experience as an auto mechanic to walk you through the likely causes and solutions to resolve the brake lamp light coming on in your Honda Accord.
Causes of the Brake Lamp Light
Table of Content
There are a few different issues that can trigger the brake lamp light to come on in your Honda Accord:
Low Brake Fluid
The most common reason for the brake lamp to illuminate is low brake fluid levels. The brake fluid reservoir may be running low and need to be topped up. I recommend regularly checking your Honda Accord’s brake fluid levels as part of routine maintenance. The brake fluid should be filled between the “MIN” and “MAX” lines on the reservoir.
Parking Brake Engaged
If you’re driving with the parking or emergency brake still on, this will activate the brake lamp light. Fully disengage the parking brake before driving to turn the light off.
ABS Sensor Issues
Problems with the anti-lock braking system (ABS) sensors can also trigger the brake warning light. Issues with wheel speed sensors or faulty ABS control modules can illuminate the lamp.
Brake Wear
As the brake pads wear down over time, this causes the brake fluid level to gradually drop as more fluid is required to move the pistons at the calipers. Low fluid levels from worn brake pads will turn on the brake lamp.
Solutions to Turn Off the Brake Light
Now that we’ve covered the likely culprits, here are solutions to try to turn off the brake lamp light on your Honda Accord:
Refill the Brake Fluid
If the fluid reservoir is low, refilling it should turn off the brake light. Use DOT 3 or DOT 4 brake fluid and top up to between the minimum and maximum lines. Be sure to check for leaks and monitor fluid levels.
Release Parking Brake
If you’ve accidentally left the parking or emergency brake engaged while driving, firmly disengaging it should extinguish the brake lamp.
Replace ABS Sensors
Faulty ABS wheel speed sensors will need to be replaced by a professional mechanic to restore proper anti-lock braking functionality.
Change Brake Pads
Worn brake pads reducing brake fluid levels will require replacement of the pads to turn off the brake light. Brake pads should be replaced in pairs on the same axle.
Bleed the Brakes
Sometimes air trapped in the brake lines can trigger the brake light. Bleeding the brakes will release any air pockets and ensure proper fluid levels.
When to Seek Professional Help
While many brake issues can be addressed with simple fluid refills or minor repairs, there are times when the problem will require a professional mechanic:
- If the brake lamp stays on after refilling the fluid and releasing the parking brake, the underlying issue is likely more serious
- Grinding noises when braking or the brake pedal sinking to the floor indicates problems with brake pads, rotors or calipers
- Leaking brake fluid points to issues with brake lines, wheel cylinders or the master cylinder
- Ongoing ABS sensor faults will require diagnosis and repair by a professional
As an experienced mechanic, I always recommend seeking professional help for any persistent brake problems or safety-related issues. It gives peace of mind knowing your brakes are in expert hands.
Driving with the Brake Light On
While your Honda Accord can technically be driven with the brake lamp illuminated, it is not recommended for safety reasons. With the light on, some key brake components may not be functioning properly, compromising stopping performance.
Braking distances will increase without full brake system functionality, so you should avoid extended driving with the brake light on. Only drive when absolutely necessary and at reduced speeds while on your way to get repairs.
Diagnosing the Cause
Pinpointing the exact cause of your Honda Accord’s brake lamp coming on does require some diagnostic tests and inspections. As a professional mechanic, here are some steps I take to troubleshoot the issue:
- Visually inspect brake fluid levels and check for any leaks
- Test brake pedal firmness and check for odd noises while braking
- Scan for ABS or other brake-related trouble codes using an OBD-II scanner
- Use a voltmeter to check for problems with ABS sensor wiring
- Test hydraulic brake system components like master cylinder, brake hoses, calipers
Thorough testing and diagnosis is key to identifying the root cause and ensures the proper fix is applied to get your brakes back to full function.
Preventing Future Brake Problems
While brake issues can never be eliminated entirely, there are some helpful maintenance tips to help prevent problems down the road:
- Regularly inspect brake fluid levels and top up if needed
- Check brake pads and rotors during oil changes and replace if excessively worn
- Flush old brake fluid and bleed the system once a year
- Listen and feel for any odd noises, vibration or changes in brake pedal feel
- Have brake components and ABS system inspected yearly as part of a safety check
- Immediately repair any identified problems with the brakes
Proactive maintenance and early repair of minor issues is crucial for reducing major brake repairs and keeping your Honda’s stopping power optimal.
FAQs About Honda Accord Brake Lights
What should I do when my Honda Accord’s brake light comes on?
Stop driving the vehicle as soon as safely possible and check the brake fluid reservoir level. Top up if low. Also ensure parking brake is fully disengaged. Avoid extended driving and have a professional inspect the brake system.
How do I turn off the brake light on my Honda Accord?
Refilling low brake fluid, releasing parking brake, changing worn pads, and bleeding brakes can turn off brake light. Persistent light will need professional diagnosis and repair.
What causes the brake lamp light to come on while driving?
Main causes while driving are low brake fluid, parking brake left on, problems with ABS sensors or modules, and brake pads worn down. Any of these can trigger the brake light.
Is it safe to drive with the brake lamp light on?
No, driving any extended distance with brake light on is not recommended. Brake system issues will lead to longer stopping distances. Only drive short distance if absolutely needed while getting repairs.
How much is it to fix a Honda Accord brake light?
Costs vary based on cause, from $75 for simple brake fluid top-up to $400+ for ABS sensor replacement or other major repairs. Diagnosis fees also apply at auto shops.
