In this article, we will examine the multiple theories and reasons why the brake pedal squeaks when letting off.
Squeaky noises, in general, or otherwise, can be extremely exasperating. When they occur frequently, it becomes even more exasperating. Problems with cars can be frustrating, and troubleshooting them can be tedious and time-consuming. When you release the brakes, do your brakes yell at you?
You may have already figured out that you aren’t the only one facing this issue. Well, if your question is: Why do my brakes squeak when I release the brake pedal, you have landed at the right place. Continue reading ahead to discover the reasons. We sincerely hope you discover the why for the squeak of your vehicle here itself.
Try and Figure Out the Source of the Noise.
First things first, one needs to figure out where the noise is based? If you need to get under the car to figure out the same, be mindful of taking all necessary precautions and, if needed, lift the car with a jack and also seek help from an acquaintance so they can help confirm the sound source as what you are considering it to be.
Inside the cabin
If the sound is from inside the cabin and does not go away even when the brake is engaged, the noise is likely from the pedal. Check this by trying the brake with the car off and in the park.
Outside the cabin
If the sound is not coming from the cabin, then the pedal may not be the reason for the squeaky sound.
Why Do My Brakes Squeak When I Release The Brake Pedal?
What can be the various possible reasons for the squeak? Let us walk through various factors that are generally identified as the root cause of the meow sound.
Brake Cable Tension
Well, brake cable tension can also be responsible for that unflattering squeak. Does the squeaking sound persist even though you have set the parking brake? Well, in a situation like this, the trouble may lie in the brake cable.
The cable might have gotten loose. A simple test to check if the cable has gotten loose will be: Lift the rear wheels from the ground and give them a subtle nudge or push, good enough to get the wheels spinning.
If they spin too far, the cable is loose. And, if they last about 1 to 1.5 revolutions, the brake cable is all good.
Worn out Brake Line
Too much incomprehensible jargon? Eh, yeah, that is how it is with cars. When was the last time you took your conveyance for a health checkup?
Your brake line might be breathing its last. The brake line from the master cylinder to the rear drum can rupture to a great extent and drain all of the hydraulic fluid. It is even scarier than it sounds. When this happens, all the brake lines need to be replaced.
Have your Brake Pads worn out?
Are your brake pads thinning? If this is the case, the squeaky sound is the brake pad’s way of letting you know that they have finished their life span. The manufacturers purposely attach these wear indicators into the brake pads so that they give a warning to the driver about the thinning of the brake pads and need to be replaced.
Squeaky Disc Brakes after a rainy day
Many brakes tend to meow after sitting in the rain, and the moisture from the same tends to get collected on the surface of the rotors. The moisture leads to the formation of a fine layer of rust on the rotor’s surface.
The pads scrape the dust off the rotors each time the rotor turns. This rust then gets caught on the leading edge of the brake pad. The rust particles further get embedded in the pad’s leading edge and cause an exasperating squeaky sound.
You can prevent this common occurrence by covering your vehicle with a cover or parking it in a garage or a similar covered roof structure.
Poor Quality Brake Pads
Poor quality brake pads comprise a high amount of metal, and they have large metal chunks pressed onto the pad material. Good quality brake pads, on the other hand, have only bits of metal.
The large metal pieces drag on the rotor and give birth to the squeak. Look for brake pads with organic brake material such as Kevlar, rubber, or fiber. They are less squeaky and cause less metal dust on the wheels.
Pulsating brake pedal
Apart from the noise, do your brake pedals also pulsate up and down when you apply the brakes? Pulsating brake pedals can be attributed to warped rotors, and Rotors tend to lose their original shape with time and usage.
Shaky brake pedals might be common if you have been hard on the brakes and have done lots of off-roading and highway drives. To cure this issue, you can either replace the rotors or resurface them. If you have made up your mind to replace the rotors, you might as well replace the brake pads because they tend to have almost the same life span.
The Drum Brakes need some lubrication.
Predominant vehicles these days come with disc brakes on all four wheels. However, some cars are built with drum brakes on the rear wheels. Does a push on the brake pedal resulting in a squeaky noise from the rear brakes?
You can cure this sound by lubricating the shoe to backing plate contact points. You must take care to use the lubricant on the back of the brake pads, on the contact points, and not on the shoe’s surface. If lubricated in time, you can prevent rusting. Rusting will eventually lead to the disintegration of the spring clip.
Go and see the dealer.
Well, you have done the adequate inspection, and now is time to see the doctor. See the dealer and make them aware of the issue and the amount of time you are dealing with it. They know the best of all and will certainly help you figure out the best possible solution to the problem.
Can I Spray WD40 on My Brakes?
WD 40 protects metals from dust, corrosion, removes moisture, and also acts as a lubricant. Yes, it is an amazing invention. However, we do not recommend spraying WD 40 on the brakes on your own. Here is why.
Although WD 40 can certainly help get rid of the squeaky sound, it can also make your brakes less effective when you need them the most since it reduces friction. Not only this, it can even break down and damage components. However, if you are still sure you want to go ahead with using WD 40, make sure you do good research on the ‘how to spray WD 40’ fairly well.
