Squeaking brakes can be bothersome and embarrassing. However, there are several things that can cause your breaks to squeal. Some of the causes may not be important and might not even cause any safety problems, while some are indicative of major problems to arise that need immediate attention. In this article, you will learn some of the major cause of brake squeals.
To clearly identify the problem, you might need to take your car for a test drive to find out when exactly the noises can be heard. You also need to know when these noises can be heard, is it during cold or warm weather?
To be sure what might be the problem with your brakes, we will discuss a few common causes that might save you an expensive trip to your mechanic.
Worn out brakes
When getting new brake pads, they will almost always come with a metal device that is attached called the “wear tabs” these little tabs are mostly what cause the squeaky noises on your brakes. In fact, they do exactly what they are supposed to do. These tabs have been made so that the brakes can make an awful noise when they are about to get completely worn out. Therefore you will need to check your brake pads to find out if they are worn out.
Insufficient brake lubrication
When you have your brake pads installed, they need to have been sufficiently lubricated on in several places, on the brake pad, and on the sliding surfaces, that will include the caliper bolts and brake caliper piston. In case this was not done, or the lubrication has worn off; it can cause the brakes to make a squeaky noise. In case you look at your brakes, and they look very dry and dusty, have your mechanic check them out, this could be a cause of squeaky brakes.
Defective Rotor surface
A new rotor needs to be shiny and smooth. But over time this surface gets worn-out by the brakes and as you drive its gets constantly heated and cooled, and this might cause rocks to build up in the brake rotors. This can cause squealing brakes. To check for this, you will need to remove the tire and inspect the braking surface carefully. The noise can also be caused by rust, if you inspect your rotor and find rust, you can take a file and file off the rust ensuring the rust does not to cause a squeal.
