If you’re driving and suddenly notice an annoying squeaking sound, it’s definitely a cause for concern. All brakes make some sort of noise, and having squeaky brakes does not necessarily mean you have a serious safety issue. In fact, most of the time, when your brakes make a squeaking sound it’s nothing to be too concerned about. Still, this high-pitched noise can be rather unnerving and annoying to you, your passengers, and other drivers on the road.
Why do Brakes Squeak?
In modern vehicles, brakes use a heavy cast-iron disc that is squeezed between two brake pads. Sometimes, this disc, the pads, and the caliper they are mounted on will start to vibrate. Most of the time, the sound they emit is at such a high frequency that you can’t even hear it. But if you notice that the squeaking increases over time or the harder you press on the brake pedal, it’s definitely something you’re probably wondering how to stop. In simple terms, squeaky brakes are caused by vibration.
Change the Brake Pads
The most common fix for squeaky brakes is to change out the brake pads. If your pads are currently made of Kevlar, consider swapping them out for pads made of ceramic or metallic material. Check with your local repair shop to find out what types of brake pads they have available and ask which types they recommend to help quell the annoying squeaking. Updating your brake pads can’t hurt since it’s a good preventative maintenance task everyone should do on occasion.
Give it a Good Coating
If you’re looking for an inexpensive and quick fix, try applying a coating to your brake pad. This slippery coating is often called brake grease or anti-seize and you should be able to find it at most auto parts stores. This coating should buffer the vibration frequency and silence that annoying sound. Do your homework and find out which brands and types work best when it comes to eliminating that awful squeaking sound.
Make a Modification
Another way to eliminate squeaky brakes is to make a simple yet effective modification. You can do this by moving the pad backing plate to the brake’s caliper piston or housing. When you move the plate, it changes the mass and vibration frequency so the squealing is stopped. In order to ensure that the backing plate stays in place, be sure to use a strong adhesive such as an anaerobic that will apply to it like a film. Place the plate firmly against the piston or housing and it should stick tightly.
