The brake pedal is one of such parts that you’ll find several people complaining about online. Brake pedals can wear out with constant use, and faulty pedals make a squeaky sound when pressed and released.

This noise can be very distracting when driving, but the good news is that a faulty brake pad can be fixed. Why does my brake pedal squeak? What can you do to resolve it? Learn more in this article.

Why Does My Brake Squeak When You Release It?

Why Does My Brake Pedal Squeak

Loss of Lubrication

A wire connects the pedal to the pedal box, which pumps fluid into the master cylinder to bring the vehicle to a halt. Over time, the area connecting the wire and pivot point dries out, and this loss of lubrication makes the contact area produce squeaking noises when you press and release the brake pedal.

This loss of lubrication is one of the common reasons why the brake pedals make disturbing sounds when you drive.

Dried Out Brake Pedal Spring

Note that a spring holds the brake pedal in place, and this spring returns to its original position when you release the brake pedal. This brake spring is usually found right above the brake pedal. However, locating it might sometimes be difficult due to its hidden location behind the firewall.Dried Out Brake Pedal Spring

Brake springs have a protective lubrication layer that usually wears off due to temperature changes and constant use. Once this protective layer wears off the spring, the brake pedals will produce squeaking sounds anytime you press or release it.

Moisture

A brake pedal comes with pads and rotors, and these two parts come in contact when you step on the brake pedal. The metal rotors are easily affected by moisture, and they can rust when moisture accumulates on their surface.

If the surface of the metal rotors is covered with rust, then the pedals will produce a squeaking noise as you drive. To prevent this, ensure to keep ice, rain, and snow away from your pads and rotors.

Loose Brake Cable

Most modern cars are designed with rear disc brakes and brake cables that are automatically adjusted. However, many cars still have drum brakes in their rear wheels. If your car has these drum brakes, the squeaking sound could be coming from a loose brake cable.Loose Brake Cable

Note that the squeaking sounds are not from the brake pedals themselves if this is the case. The squeak sounds result from a loose connection between the brake cable and the rear brakes.

Heavy Use

If you’ll be driving for hours or days, it’s a good idea to rest the brake pedals from time to time. Constant pressure on the brake pedals and aggressive stopping can cause the brake pedals to overheat and produce squeaky noises.

Note that if you ignore this overheating issue, you may have to take your car to a professional for repairs.

Dirty Drum Brakes

If your car uses a drum brake, note that dust and soot accumulation can clog the brakes. You’ll find these brakes within the drum, and this drum house collects dirt over time. Soot build-up can affect the drum brake’s functionality, resulting in annoying squeaky sounds when you step on the brake pedal.Dirty Drum Brakes

However, the cause of these squeaks may actually be the rear brakes and not the brake pedals as commonly assumed.

Worn-Out Rotors or Drum Brakes

Although your rotors and drum brakes can serve you for a long time, they do tend to wear out with time. The shiny outer part of the brake rotors and the inside of the brake drums are easily affected by constant pressure and friction.

Thin rotors and drum brakes can cause the car to produce squeaky noise whenever you step on the brakes.

How Do You Fix a Squeaky Brake Pedal

Now that you know what causes the squeaky noises when you release your brake, here’s information on how you can fix that

  • Take some short breaks on your long rides and allow your brake pedals to breathe for a while to prevent overheating from overuse.
  • Apply a grease spray to moisten the spring. You can also use some Lithium grease or WD-40 on the spring. Furthermore, finding the spring can be tricky, so make sure you spray directly on it.
  • For loose cables, the best solution is to adjust the rear drum brakes every 20,000 miles. It’s a straightforward procedure that you can carry out on your own. Tightening the brake line helps to reduce the occurrence of brake squeaks.
  • If you have dirty drum brakes, take some time to clean them. Take off the top cover of the brake and then clean the insides. Wipe the dirty areas with a brake spray cleaner. Furthermore, make sure to lubricate each point so you won’t have to open and clean the brakes again soon.
  • If the issue is with your brake drums, you can either fix or replace them. However, if your rotors are worn-out, then note that you’ll have to get a new set as this part of your car is irreparable.
  • Take your car for repairs or have a mechanic look at it if everything else fails. They have the skills and knowledge to deal with such issues.

Conclusion

Keep in mind that how well you take care of your car will determine how well it will serve you. If your car makes a squeaky noise when you hit the brake pedal, then it’s time to have a look at your brakes.

These squeaky sounds may be caused by loss of lubrication, moisture, heavy usage, and others. If you’ve done everything and the squeaky sound persists, it’s best to take your car to a certified mechanic.
