Brake Pedal Makes Noise When Released

What should I do if my brake pedal makes noise when released? What could be the reasons and what can be done to fix it? In this article, we will talk about this problem.

If the brake pedal squeaks when pressed and released, there is a high chance that some of the components of the brake pedal are worn out. A loss of lubrication will also cause a brake pedal to make a squeaking noise when you press or release it.

Depending upon the noise you hear, you can determine its possible cause. If you hear a squealing sound, there is a high chance that the brake pads are worn out and need replacement.

If there is grinding noise when letting off the brake, the chances of a worn-out brake pad are also high. A rattling sound is caused due to some loose components, which will eventually result in a damaged brake pad. Read on below to find the possible reasons for your brake pads to make noise when released or pressed.

Why Is My Brake Pedal Squeaking?

If the brake pedal makes noise when released, then a worn-out part is likely the cause. Some of the possible reasons for your brake pedal to make noise when you either press or release it can be.

#1. Bad Brake Pedal Spring

A brake pedal spring is responsible for the brake pedal returning to its original position after you have released it. The spring is situated just above the brake pedal beneath your dashboard. 

The spring contains lubrication which allows its proper functioning. With regular use and exposure to high temperatures, the lubrication can dry out and make a squeaking or creaking noise when letting off the brake

Spraying some grease will solve the issue for you. Just make sure to locate the spring and spray sufficient quantities.

#2. Brake Cable 

If your car still has drum brakes, then there is a high chance that the noise you hear while releasing your brake pedal can be due to the loose brake cable. The problem here is not associated with your brakes but with the cable. If you own a vehicle with rear drum brakes, it is better to adjust the brake cables every 20000 miles.

#3. Dried Lubrication

The brake pedal connects to the pedal box with the help of a wire. When you press the brake pedal, the wire pushes the brake fluid from the master cylinder, which brings the car to a stop. The lubrication between the wire and the contact point dries with continuous uses and causes squeaking noises when you press or release the brake pedal. One of the most common causes is if your brake pedal makes noise when pressed. If this is the issue, you can quickly solve it by spraying a sufficient quantity of grease where the wire connects to the pedal box.

#4. Worn Out Brake Line

A worn-out brake line can also be the possible reason for a brake pad to make noise when being pressed or released. The brake fluid applies high pressure on the brake line, and with time it can become weak and eventually break. 

If your car has traveled for hundreds of thousands of miles and never once is the brake line repaired or replaced, then there is a high chance that the noise you hear is due to a faulty brake line.

Hitting speed breakers or stones while driving can also cause the brake line to break. Every time you take your car for servicing, make sure to get the brake line checked.

#5. Dirt 

If your car has drum brakes, then there is a high chance the grime lodged between the drum and brake shoe is the reason. The drum brakes are prone to accumulating dirt over time with the motion between the brake shoe and the drum. 

If you hear a noise when you press or release the brakes, you should try cleaning the brakes. You can do the cleaning yourself or take your car to a mechanic.

#6. Worn Out Parts

Brakes in a vehicle are made of several different components, and any noise you hear while pressing or releasing the brakes can be a symptom of a worn-out part. The rotors and brake drums can wear out and squeak when applying or releasing the brakes.

A worn-out brake drum can be repaired, but a rotor would need a replacement.

Why Do Brakes Squeak When Letting Off The Pedal?

If your brake pedal makes noise while you press or release it, it is most likely that one of its components is worn out or malfunctioning. Brakes are one of the most essential parts of your vehicle when driving safely, and you should never ignore any issue with the brakes. 

#1. Brake Pads Worn Out

If you hear a grinding sound while pressing or releasing the brakes, then there is a high possibility that your brake pads are worn out, and the sound is coming from the caliper coming in contact with the rotor disk.

#2. Object Stuck in Caliper

If your brakes are making a grinding sound, then it is better to get them serviced as soon as possible. Another reason your brake pedal makes noise can be some foreign object getting stuck in the caliper.

#3. Brake Pads have Expanded

A rattling sound when you apply or release the brake pedal is sometimes caused due to expansion of brake pads. The brake pads expand due to heat.

Frequently Asked Questions?

#1. What Is The Whistling Noise From A Car That Stops When I Brake

The whistling noise that comes from your car and stops when you press the brake indicates something wrong with your car brakes. 

The most likely cause is that the brakes are wearing out, and the brake wear indicator is making contact with the rotor, causing the whistling sound. Get your car checked out at a mechanic to avoid any severe damage.

#2. When I Apply Brake I Hear A Clicking Noise?

If you wonder about the click sound when I press the brake, there is some problem with the brake calipers. The brake caliper’s function is to keep the brake pads in place. 

If you hear a clicking noise when pressing the brake pedal, the calipers have become loose. Depending on the damage, you need to get them repaired or replaced. If you hear a clicking noise when pressing the brake in the park, it is normal. 

There is a shift lock mechanism in your car which allows shifting out of the park when you press the brake pedals on your car. The mechanism is electrically operated, and the click that you hear is the sound of the shift lock solenoid operation.

#3. What Does A Bad Brake Caliper Sound Like?

A bad brake caliper will sound like something is grinding or scraping. When the brake calipers have started to wear out, they will make a rubbing sound when you release the pedal. 

A bad brake caliper will make squeaking and rattling sound similar to the sound made by worn-out brake pads.

#4. What Are The Rubber Hairs On Tires Called?

The rubber hairs on tires are known as vent spews or tire nibs, sprue nubs, gate marks, or nippers. The main function of these vent spews is to allow ventilation for the tires.

A Few Final Words

There can be several reasons behind your brake making noise when you release it. A worn-out brake pad also can cause a metallic sound. 

Any leakage in the brake lines or faulty brake cylinders can result in the brake pad touching the disc even after releasing the brake, resulting in the noise you hear. Corrosion in the brake or handbrake can also be a possible cause of the noise.
