Even if your automobile is modern and properly maintained, you may detect occasional squeaks. This is particularly common in older and high-mileage automobiles because their components wear out regularly.
Some delicate components wear out quicker than others due to continual use, and the brake pedal is an example of such a component. Most motorists will encounter this problem at some point or another, and it can be irritating due to its loudness.
What Causes My Brakes to Squeak?
Why is my brake pedal squeaking? It is one of the common questions you will find several motorists asking. Let us delve into some of the most common causes of squeaking brakes.
1. Dry Brake Pedal Spring
The brake pedal remains in place because of an elastic spring that allows it to return to its previous position. That spring can be found above the pedal, although it is usually difficult to see because the firewall conceals it.
Frequent usage and heat variations often wear away the protective coating of lubricant on the spring. Consequently, this results in squeaking each time you press or release the brake pedal.
Solution: Use white Lithium grease or WD-40 spray to lubricate the spring positioned right above the braking pedal. Additionally, always make certain that you spray directly on it because it is tough to find. Also, spray a considerate amount so that it lasts a long time.
2. Lack of Lubrication
A wire connects the pedal to the pedal mechanism. The wire is responsible for pumping fluid into the master cylinder to brake the automobile. The connection section between the wire and the pedal box becomes dry with time, which causes squeaking noises while pushing and releasing the brakes.
Probably the most common cause of squeaking brake pedals is this. If your brakes squeak, then there is a strong likelihood that your brake pedal has the same issue.
Solution: Spraying white Lithium grease or WD-40 spray on the spot where the cable connects to the pedal unit is the simplest and most effective way to solve this issue. If the squeaks originate from this connection area, they will cease.
3. Loosened Brake Cables
When the disc brakes are used in the back in most modern vehicles, all the other brake lines are adjusted automatically. Nonetheless, there are still many automobiles that still use the drum brake system in their back wheels. If your automobile uses drum brakes, then there is a significant chance that a loosened brake line produces the squeaks you hear every time you press the brake pedal.
It is crucial to highlight that the squeaks in this situation result from loose brake wire connecting to the back brakes and not the brake pedals.
Solution: Brake cords in automobiles with rear drum brakes need calibrating every 20,000 miles. Luckily, this is an easy process that you can successfully handle on your own. A tight brake cable improves the grip of your brakes and reduces the likelihood of brake squeaks.
4. Worn Out Brake Lines
Among the most prevalent reasons for brake pedal squeaks is a worn or stretched brake line. Even when you jack up your vehicle, you may not easily detect a worn-out brake line. The tremendous pressure of the braking fluid weakens the brake lines over time, and they can break at some point. If your automobile mileage is 100,000 or more, and you have had its brake line checked or replaced, it is highly likely to make squeaking sounds.
Most vehicles have a plastic skid panel fitted to their undercarriage that shields the brake cables. However, it can break after striking speed bumps or stones. Thus vehicle brake cables should be examined regularly to look for signs of wear and strain.
Solution: Always get your brakes tested anytime you take your vehicle to a service shop for regular maintenance. If your vehicle mileage is over a hundred thousand miles, it is a prudent option to replace the brakes. New steel brake cables are inexpensive, and a wise investment, especially because torn brake lines are very dangerous.
5. Worn-Out and Warped Rotor, or Brake Drum
Due to constant contact, the inner parts of the brake drums and the outside shining coating of brake rotors tend to wear away over time. This can result in squeaky noises when you use the brakes, and you may believe the noise is coming from the brake pedal when it is actually coming from within the wheels.
Solution: If your brake cylinders are worn out, they can be restored or changed; however, you will need to purchase a new rotor seeing as they are irreparable.
6. Dirty Brake Drums
Drum brakes become blocked due to dust and grime generated by friction between the drum and brake shoe. The primary reason for this is that these brakes are encased in a drum, which causes filth to collect over time. The dirt might impair the performance of the drum brake, causing the brakes to squeak.
Solution: You can wipe the drum brakes yourself. Start by removing the tire, giving the brake a small thump, and removing the top cover. Wipe inside the cover and the brakes with a brake spray cleaner, then apply a touch of oil.
How Do You Fix a Squeaky Brake Pedal?
As discussed above, various reasons might be causing your brake to squeak. Fixing your brakes will require that you ascertain what precisely is the problem. Go through the problems outlined above and determine what makes your brakes squeak. Then, apply the solution recommended under that specific problem.
Nevertheless, if the problem persists, you should take the vehicle to a mechanic professional.
Is It Safe to Drive With Brakes Squeaking?
The answer here is not as straight as a YES or NO. Some of the problems that might cause your brakes to squeak might not be immediately threatening to your safety. In these instances, people have reported that they could still safely drive their vehicles while the brakes were squeaking.
However, we do not recommend this. The main reason is that you cannot openly see the problem, and thus you will not be able to judge its severity. Also, we all know how brakes are important. We recommend that you fix any problems making your brakes squeak immediately. If you cannot do it yourself, please get in touch with a professional to do it for you.
Are you one of the people asking, why is my brake pedal squeaking? We recommend that you always begin with the fundamentals and move onward to the more sophisticated parts. If you’ve tried everything and nothing seems to be working, it’s time to take your vehicle to a service shop. Additionally, remember to tell the mechanic about everything you’ve done, so they have a clear picture as to what is wrong with your vehicle.
