What Causes Car Brakes to Squeak? 

At first, you’re driving along with nothing but the sound of your engine and maybe some music playing in the background.

First of all, let’s put one myth to rest right now. Squeaking car brakes isn’t always a sign that something is wrong with them or that they need to be replaced. In fact, there are some instances where squeaking brakes are normal. Have you noticed that after a rain storm, your brakes tend to squeak the first few times you try to use them? That’s because the water causes a thin layer of rust to accumulate on the brake rotors, and the squeak you hear is due to the pads scraping that layer of rust off when the brakes are used. This is completely normal. 

Sounds and Signs Your Brakes Need Fixing or Replacing

One reason may be that your brake pads are thinning, and in this case, the squeaking is actually designed to alert you to this fact. As the brake pads wear, a metal tab edges closer to the rotor. When it makes contact, it will let out a high-pitched squeak to let you know those pads need to be replaced. 

Another thing that can happen is that the brake calipers stick and leave the brakes partially applied. When this happens, something called glazing occurs, where the constant contact hardens the brake pads to cause a squeak. Other things to watch out for include broken anti-rattle clips, or improper lubrication if your car has drum brakes.

    Thanks for sharing the notable causes of a squeaky automotive brake system. I would like to tell that a squeaky brake is a typical thorn in the vehicle owner’s flesh. However, providentially it is relatively effortless and economical to fix. Sometimes, a typical condensation moisture can be the reason behind the squeak in the morning time. While in some other instances, a rust embedded rotor and a worn-out brake pad can give rise to this same complication. Whatever may be the cause, you can’t take any source of irritation lightly, especially when it comes to safety. Rather you should call a car mechanic and upgrade your convertible’s braking system to drive safely on the highway.

    Thanks for sharing such an informative blog. Brakes are one of the important parts of the vehicle and need regular maintenance. Sometimes car brakes produce some abnormal sounds like squeaking, grinding or cunning .Most car brakes squeak due to the effect of rain, dew and condensation. Actually the moisture from rain,dew and condensation collects on the surface of rotors. When moisture collect on the brake rotors it causes a thin layer of rust to form on the rotor surface.

    Brake is an important safety component of the car. Sometimes the brakes of the car produce some unusual noise like squeaking. There are different reasons for this. One of the reasons is thinning of brake pads. When the brake pads become thin, we hear an unusual noise like squeaking which alerts us about the fact. Other reasons for squeaking are- sticking of brake calipers, improper lubrication etc. Whenever this squeaking noise is heard continuously for a long period, we should visit a certified auto repair center for brake pad replacement.
