Why Brake Light is Flashing On Jeep Wrangler: & What To Do?

If you are seeing Jeep Wrangler flashing brake light and trying to figure out whether or not you should drive your Wrangler, check the emergency brake first.

The brake light indication on a Jeep Wrangler is meant to alert you to a problem with the braking system. The anti-lock brake system, on the other hand, has its own ABS warning light. The brake light indicates a problem with the braking system’s physical components.

The brake light will remain illuminated if it is engaged. If the handle isn’t fully depressed, the brake warning light will remain illuminated. Read this article to figureout more.

Why Does a Brake Light Flash on a Jeep Wrangler?

The brake warning light signals that one of your Jeep Wrangler’s key braking components has failed, which is usually indicated by a loss of pressure. You’ll notice a reduction of pressure in the brake pedal, which will feel “mushy.”

If the brake light only illuminates when you use the brakes, the braking pressure in the system is likely to be too low. Either the brakes need to be bled or a leak exists.

Brake Fluid Leak

Now that you’ve tested the emergency brake handle on Jeep Wrangler, go ahead and check the master cylinder to determine whether the brake fluid is low. Adding extra may give a temporary relief if it is low but not empty.

If the brake fluid appears to be completely depleted, you’ll need to add extra, bleed the brakes, and, ideally, correct the problem so that you don’t have to go through this process again. Poor braking performance is indicated by brake fluid seeping out over the brake pads and shoes.

Remember that it had to leak someplace, and that adding fluid without addressing the source is only a band-aid. The leak may worsen over time, resulting in brake failure.

Pressure Differential Switch

There are two circuits in your brake system. The brake system is split in half by these circuits. You’ll still have brakes on half of your Wrangler’s wheels if the braking system leaks or malfunctions.

The pressure differential switch detects a difference in pressure between the two circuits and illuminates your Wrangler’s brake warning light to indicate a problem. This switch is usually found in the master cylinder of most automobiles. There should be a harness plug someplace in there.

Check the Brake Lights

If the real brake lights behind it fail, certain vehicles will now trigger the brake warning light on the dash. Check to see if both of them are glowing. If it doesn’t work, try changing the bulb to see if that fixes the problem.

Additional Symptoms to Look for When the Brake is Damaged

There are some more symptoms to look for a damaged break when Jeep Wrangler flashing brake. Look for these to know more:

1. Squealing or Squeaking Noises

New brake noises aren’t necessarily an indication of a problem. It’s possible that a foreign object has been trapped in your brakes (a pebble or debris).

It might possibly be the wear indicators on your brake pads. When you press the brakes, these metal particles in your brake pad make contact with the rotor, causing a high-pitched screech.

This indicates that your brake pads need to be changed.

2. Grinding Noise

Grinding noises, whether from disc or drum brakes, may indicate that your brakes require immediate attention because the brake pad or shoe is scraping against metal contact points.

When you hear or feel grinding, a trip to Les Schwab is suggested.

3. Wobbling or Vibration When Breaking

It’s possible that the thickness of your rotor is uneven if your steering wheel or car rattles or vibrates when you use the brakes. Brake rotors are huge discs that reside inside the wheels and serve as brakes.

When you apply the brakes, the brake pads contact the rotors, preventing the wheels from spinning. It’s natural for the rotor surface to wear down and become uneven over time.

When you use the brakes, the pad material transfers to the rotor surface due to friction. You may notice vibration when braking if the pad material transmits unevenly.

If the material is left uneven, it will continue to develop on the uneven regions, worsening the problem over time.

The face of the rotor should be smoothed or evened out during brake service to repair defects and prevent a wobble during braking.

The rotors will need to be replaced if they are too worn to be maintained.

4. Spongy or Soft Breaks

You want to feel some resistance when you apply the brakes. It might suggest air or moisture in the braking system if they feel soft or the pedal goes all the way to the floorboard.

It’s also possible that the master cylinder is malfunctioning. It’s critical that you contact Les Schwab as soon as you identify these problems.

5. Car Pulling to One Side When Breaking

This might be the result of a faulty brake line or a caliper problem, among other things. When this occurs on the front brakes, one brake may operate while the other does not.

This results in a pull in the direction of the braking force-producing side (still working). It can go unnoticed if only one rear caliper is malfunctioning. Regularly inspect your brakes at Les Schwab to catch problems early.

6. Burning Smell

Overheated brakes can produce a harsh, chemical stench. Pull over to a safe location and let the brakes cool down to avoid brake failure.

Make sure the parking brake is turned off. If you see smoke coming from a wheel, it’s possible that the brake caliper has failed and is stuck in place. In this instance, driving without rapid repairs might be dangerous.

Do You Need To Stop Driving If the Break Light Start Flashing?

If you ever feel uncomfortable or like you’re losing control of the car while driving, pull over to a safe spot and halt.

However, a brake warning light does not necessarily indicate that you must stop immediately. What to do in each case is as follows:

  • You can continue driving to a repair shop if your brake warning light turns on but your brakes feel okay and your brake fluid levels are normal. It might just be a sensor malfunction.
  • If the warning light flashes but you have to pump the brake harder than normal, pull over to the side of the road as soon as possible and contact your breakdown service for assistance.

After you’ve come to a complete stop, check the brake fluid levels. If it’s safe to do so, top up your gas tank and test your brakes.

If the warning light turns off and your brakes feel normal, you can go gently to a repair shop. Even if you think you’ve corrected the problem, it’s always a good idea to get your brakes examined if the warning light comes on.

Is It Expensive to Troubleshoot?

It is not expensive to troubleshoot your Jeep Wrangler breaks. If you are seeing symptoms of a damaged break, you should get your Jeep checked as it is a very crucial part of the vehicle.

How to Turn the Flashing Lights Off?

When the brake pedal is pressed, the only method to turn off the brake light is to restore adequate line pressure to both brake circuits. Do not drive your Jeep Wrangler if it is having difficulties stopping or is leaking fluid.

Allow it to be hauled to a mechanic. If you make a mistake when repairing your engine, the car will not move. It won’t stop if the brakes aren’t fixed correctly. That’s a thousand times more risky.

Final Words

If the Jeep Wrangler flashing brake, and you’ve tested the emergency brake, look for a leak in the lines, calipers, wheel cylinders, master cylinder, and other areas. Good luck figuring out what’s wrong. If you have anything to contribute, please do so in the comments section below.
