Read Freeway\u2019s guide to squeaky brakes and belts below to get started.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Do Car Brakes Do?<\/strong><\/h2>\n\n\n\n<p>Your&nbsp;car\u2019s&nbsp;brake system allows you to slow down your vehicle by creating friction, which involves pressing its brake pads against its rotors. As these two components rub together, they inevitably wear down. Because brake pads are designed to wear down slowly, you&nbsp;don\u2019t&nbsp;have to be concerned about a bit of brake dust. However, you should be aware of signs that&nbsp;it\u2019s&nbsp;time to replace your pads or brake rotors, such as significant squeaking.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Reasons for Squeaky Brakes<\/strong><\/h2>\n\n\n\n<p>Squeaking occurs when something rubs against your brake rotors at a high frequency. Sometimes,&nbsp;it\u2019s&nbsp;just brake dust, moisture, the normal texture of your brakes, or components from&nbsp;your&nbsp;<a href=\"https:\/\/www.freeway.com\/knowledge-center\/auto\/auto-tips\/anti-lock-brakes\/\" target=\"_blank\" rel=\"noreferrer noopener\">anti-lock braking system<\/a>. In other cases,&nbsp;it\u2019s&nbsp;a sign your brake pads are getting too worn. There are a few main reasons you might have&nbsp;squeaking&nbsp;or squealing brakes:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Worn-Down Brakes<\/strong><\/h3>\n\n\n\n<p>Modern brakes have a metal wear indicator on the brake pads to alert you when they are wearing down. A small piece of metal built into the base of the pad will start poking through as the top of the pad wears away. The exposed metal from the brake pad wear indicator creates a high-pitched screech to let you know&nbsp;it\u2019s&nbsp;time to take your car in for&nbsp;<a href=\"https:\/\/www.freeway.com\/knowledge-center\/auto\/5-essential-car-maintenance-tips\/\" target=\"_blank\" rel=\"noreferrer noopener\">automotive maintenance<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>New Brake Pads May Squeak Initially<\/strong><\/h3>\n\n\n\n<p>When you get new brake pads, you might hear some squeaking and squealing. It takes some time for the surface of the rotors and the brake pads to adjust to one another. After a few hundred miles, you can expect the&nbsp;initial&nbsp;new-brake&nbsp;sounds to go away.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Cold Weather Effects<\/strong><\/h3>\n\n\n\n<p>You might also notice that your brakes suddenly get squeaky after a cold, rainy day. Moisture can create a thin layer of rust on your rotors. The debris from the rust will cause a squealing sound until the rust wears off as you drive.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>High-Performance Brakes<\/strong><\/h3>\n\n\n\n<p>A high-performance brake system may squeak more than standard brakes. High-performance brake pads are often made from a more rigid material that will squeak a bit more until the brakes reach&nbsp;optimal&nbsp;operating temperatures. <\/p>\n\n\n\n<p><img decoding=\"async\" width=\"1000\" height=\"667\" class=\"aligncenter wp-image-12420 size-full\" src=\"https:\/\/www.freeway.com\/knowledge-center\/wp-content\/uploads\/sites\/2\/2020\/09\/Freeway-squealing-belts-and-brakes-2.jpg\" alt=\"Men's feet inside a car showing squealing brakes.\n\n\" srcset=\"https:\/\/www.freeway.com\/knowledge-center\/wp-content\/uploads\/sites\/2\/2020\/09\/Freeway-squealing-belts-and-brakes-2.jpg 1000w, https:\/\/www.freeway.com\/knowledge-center\/wp-content\/uploads\/sites\/2\/2020\/09\/Freeway-squealing-belts-and-brakes-2-300x200.jpg 300w, https:\/\/www.freeway.com\/knowledge-center\/wp-content\/uploads\/sites\/2\/2020\/09\/Freeway-squealing-belts-and-brakes-2-768x512.jpg 768w, https:\/\/www.freeway.com\/knowledge-center\/wp-content\/uploads\/sites\/2\/2020\/09\/Freeway-squealing-belts-and-brakes-2-750x500.jpg 750w, https:\/\/www.freeway.com\/knowledge-center\/wp-content\/uploads\/sites\/2\/2020\/09\/Freeway-squealing-belts-and-brakes-2-294x196.jpg 294w, https:\/\/www.freeway.com\/knowledge-center\/wp-content\/uploads\/sites\/2\/2020\/09\/Freeway-squealing-belts-and-brakes-2-320x213.jpg 320w, https:\/\/www.freeway.com\/knowledge-center\/wp-content\/uploads\/sites\/2\/2020\/09\/Freeway-squealing-belts-and-brakes-2-285x190.jpg 285w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Do Car Belts Do?<\/strong><\/h2>\n\n\n\n<p>Car belts use rotation to transfer energy from your&nbsp;car\u2019s&nbsp;engine to other components and accessories. There are multiple types of car belts, but the main two are the timing belt and the serpentine belt, also known as an S-belt or drive belt. Other types include fan belts and alternator belts.<\/p>\n\n\n\n<p>Like your brakes, a belt that wears down can make a squealing sound. That said, it can still be functional and last much longer in many cases. However,&nbsp;it\u2019s&nbsp;essential to inspect it before you end up stranded or&nbsp;damage&nbsp;your engine, especially if&nbsp;it\u2019s&nbsp;a loud, ongoing noise that happens&nbsp;frequently&nbsp;when you drive.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Understanding Squeaky Belts<\/strong><\/h2>\n\n\n\n<p>The most common reason for the squeal is that, as the belt approaches the end of its life, it will begin to slip. Though it may still have some grip, the friction and heat generated as the belt slips over the various pulleys that control your fan, water pump, and power steering will cause it to squeal before it lets go.<\/p>\n\n\n\n<p>In some cases, the belt may simply need a dressing or conditioner to remove debris, prevent slippage, and extend its lifespan. However,&nbsp;it\u2019s&nbsp;always best to check out the source of a squeaky belt and see if you need a full replacement.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Serpentine Belt Concerns<\/strong><\/h3>\n\n\n\n<p>The serpentine belt is one long winding strip that connects to multiple components in your car, including the alternator and the air conditioning compressor. If it starts squealing, it could be misaligned, worn down, or lacking sufficient tension. If the belt has visual signs of cracking, fraying, or glazing,\u00a0it\u2019s\u00a0time to replace it before your car becomes a\u00a0<a href=\"https:\/\/www.freeway.com\/knowledge-center\/auto\/driving-safety\/is-your-vehicle-safety-hazard-on-the-road\/\" target=\"_blank\" rel=\"noreferrer noopener\">safety hazard on the road<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Impact of Belt-Driven Components<\/strong><\/h3>\n\n\n\n<p>The belt itself may not be the root cause of any strange sounds&nbsp;you\u2019re&nbsp;hearing. If one of the engine accessories driven by the belt is having an issue, that&nbsp;component&nbsp;could be at fault. If an engine&nbsp;component&nbsp;is malfunctioning, it could add extra strain to the&nbsp;whole system, so&nbsp;it\u2019s&nbsp;helpful to conduct a thorough inspection of your belt tensioner, alternator, air conditioning compressor, and other connected parts.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Don\u2019t&nbsp;Ignore the Noise! Protect Your Car and Wallet with a Free Quote!<\/strong><\/h2>\n\n\n\n<p>Being able to decode your car\u2019s sounds is a valuable skill that can help you&nbsp;determine&nbsp;when to bring your vehicle into the mechanic and when to hold off. However,&nbsp;it\u2019s&nbsp;always best to err on the side of caution. If you&nbsp;can\u2019t&nbsp;think of&nbsp;a reason why&nbsp;your car brakes might be squeaking, or you start hearing a new squeal from your engine, getting a quick inspection can give you peace of mind and catch any issues before they get too serious.<\/p>\n\n\n\n<p>When it comes to investigating strange sounds coming from your brakes and belts,&nbsp;it\u2019s&nbsp;better to be safe than sorry.

If you hear a deafening squealing sound or a sound that lasts longer than a few seconds,&nbsp;it\u2019s&nbsp;best to head to a mechanic as soon as possible.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Can Switching Brake Pad Types Reduce Squealing?<\/strong><\/h3>\n\n\n\n<p>Yes, switching to a different brake pad style could reduce the frequency or volume of squealing brakes. For example, ceramic pads are designed to minimize vibration and reduce squeaking.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What Is the Life Expectancy of a Serpentine Belt?<\/strong><\/h3>\n\n\n\n<p>Serpentine belts typically last from 50,000 to&nbsp;100,000 miles. The exact life expectancy of your S-belt depends on many factors, such as the make and model of your vehicle, your driving habits, and the quality of the&nbsp;component.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why Is My Car Belt Still Squealing After Changing It?<\/strong><\/h3>\n\n\n\n<p>If you just replaced a belt in your car and&nbsp;it\u2019s&nbsp;still squealing, the sound could be due to misalignment, poor&nbsp;tensioning, or another faulty&nbsp;component&nbsp;in your car. If your belt was correctly installed and&nbsp;there\u2019s&nbsp;no fluid contaminating the area, a defective belt tensioner may be causing the issue.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hearing an unexpected noise from your car is always stressful, especially when&nbsp;it\u2019s coming&nbsp;from a critical&nbsp;component&nbsp;like your brakes or one of the belts in your engine.
