How To Know If You Need New Brake Pads – — If your car’s brakes squeak, squeal, or make an ominous grinding sound when you press the pedal, you may need new brake pads or rotors. The same goes for if the brake pedal travels longer than usual before you feel a lot of braking force, or if it just feels like your car takes longer to stop. If the red brake warning light on your dashboard comes on when you press the pedal, you may have missed the previous warning sign and need to go directly to a repair shop.
But sometimes, you may hear squeaks or squeals because the brakes are covered in moisture, light surface rust, dirt, or grime, especially if the car has been parked overnight or for a few hours. After you depress the brake pedal a few times or more, these noises may disappear (and the brake pads have cleared the rotor or drum of harmful material). The noise may also be caused by loose brake pads or calipers.
How To Know If You Need New Brake Pads
If you hear a high-pitched scraping sound, your brake pad wear indicator may be warning you that you haven’t had your car’s brakes repaired in a timely manner.
Why Are My Brakes Grinding?
Because there are many possibilities, the best way to tell if brake repair is needed is to have a shop check the condition of the entire brake system, including the rotors (or rear drum on some vehicles), brake pads (friction). The material that squeezes the rotor or drum), calipers and other hardware, as well as the master brake cylinder and fluid lines to each wheel.
Your ears and the feel and performance of your brakes can tell you a lot about the condition of your brake system, but a repair shop can tell you even more about what’s wrong and what needs to be fixed. For example, excessive brake pedal travel may mean worn brake pads, but it may also be caused by insufficient brake fluid. While the symptoms may be the same, the treatments are very different.
The repair shop should not only observe the brakes to identify the problem, but also measure the thickness of the brake pads and rotors and whether they are wearing evenly. Manufacturers have different recommendations on when to replace brake pads, but as a guide, some shops recommend replacing them with new ones when only 20% of their original thickness remains. Others say this is necessary when pad sizes are as small as 3/32 inch. Depending on the vehicle, new brake pads can range in size from about three-eighths to half an inch.
If you’re concerned that a repair shop is trying to take advantage of you by recommending a brake service you don’t need, first explain in detail what they say you need (also ask them to show you worn parts), and then get a second opinion.
Brake Pads: 4 Signs You Should Replace Your Pads
Brakes wear out gradually, so you may not notice a slow but steady decrease in stopping power. A good way to keep tabs on the condition of your brakes is to check them every time you change the oil. This may serve as a reminder that you’ll need new brake pads or rotors within the next few months, giving you time to choose where and when the work will be done.

How To Know If Motorcycle Brake Rotors Can Be Resurfaced
Expert Review 2024 Ford Mustang Dark Horse Spins Fast: Impressively Capable, Surprisingly Civilized By Mike Hanley Senior Road Test Editor When you press the brake pedal, the brake fluid transfers the pressure on the pedal to calipers so that they squeeze the surface area of your brake pad rotors. The friction created by the pads pressing against the rotors slows the rotation of the wheels and stops the vehicle from moving.
The new rotor has a smooth and even surface. Over time, the rotor loses its smooth surface. Worn rotors can increase stopping distances and reduce braking performance, creating dangerous situations.
Knowing when you need new rotors is crucial. In this guide, we discuss common signs that indicate your rotors need to be replaced, as well as the consequences of not getting new rotors when you need them. First, we’ll explain the importance of knowing brake rotor thickness and why it’s important to your braking performance.
Brake disc thickness is a key measurement for vehicle safety. It is important to know your vehicle’s minimum brake disc thickness because if the brake disc is thinner than the minimum thickness, operation may be dangerous. Thinner rotors are lighter and have less ability to absorb and dissipate heat. When a brake disc is thinner than minimum, its strength is also reduced, which can lead to an increased risk of breakage or brake failure.

Want to machine/cut brake discs or worried about them wearing out too much? You need to know the minimum thickness. The minimum thickness of the rotor tells you the minimum operating level of the rotor. This scale can be engraved on the side of the rotor, within the texture of the rotor, or on the cap of the rotor.
To measure the minimum operating thickness of a rotor, place the micrometer at the thinnest point on the rotor surface where it contacts the brake pad. If your rotors are worn beyond this thickness or need to be cut, you will need new rotors.
Your rotor may show signs of disc thickness variation (DTV). This term describes the change in thickness of a disc rotor’s braking surface as it rotates on its axis. A DTV may indicate a more serious problem with your braking system.
Whenever you inspect your brake pads, you must also check the rotor thickness. If the brake disc thickness is less than the minimum specification and cannot be resurfaced, the brake disc should be replaced immediately.

It’s a good idea to have your brakes inspected every 10, 000 miles or every time you replace the brake pads. If your brake pedal vibrates when you press it, or if you notice that your brakes start to squeal or pull to one side, you may need to have your brakes inspected as soon as possible. Proper maintenance will ensure your rotors have enough metal to brake safely.
We recommend replacing both rotors at the same time, even if one still works, as the difference in rotor thickness may cause the brakes to pull to one side.
If you notice any of the following conditions, it may be time to replace your brake rotor. The 10 most common signs you may need new rotors include:
The longer it takes to replace a worn or damaged brake rotor, the more problems you’ll have down the road. Your rotors and brake pads work together, so a damaged rotor will eventually damage the brake pads and possibly the caliper.
How To Tell If You Need New Brake Rotors
Wear beyond the minimum thickness level may cause other problems that require replacement of other components of the brake system.
Essentially, if you fail to replace the rotors when necessary, it can cause a knock-on effect that damages the entire braking system.
Most importantly, bad rotors put your safety and the safety of those you share the road with at risk. You cannot jeopardize your safety or the safety of other drivers and pedestrians by improperly maintaining your vehicle. When you notice a faulty brake rotor, you need to correct the problem.
In this article, we explain the importance of understanding and identifying minimum rotor thickness and the top ten signs you may need to replace your rotors. If based on this information you find that you need to replace the rotors, we recommend that you use the stock replacement rotors or upgrade to drilled and slotted rotors. Our drilled and slotted rotors are galvanized to reduce braking temperatures and increase performance.

The brakes are a part of your car that you never want to risk. While every system on your vehicle is important, the difference between good brakes and bad brakes can be the difference between life and death. That’s why you need to make sure your rotors are running 100% at all times. If something goes wrong, the results can be catastrophic.
The braking system on a car consists of several key components. There are brake pads, calipers and brake discs. If you go looking for rotors, you can easily find them.
