After reading this article, you will understand all the what’s and whys about brake pads and how brakes work.

Understanding your car and how it works leads to safer and more responsible driving for everyone.

Through learning the facts, issues, and prevention strategies, you will be ready to face whatever your breaks throw at you.

What are Brake Pads?

While many people pay large sums for new brake pads, many don’t know what is being replaced.

To put it simply, brake pads are what your brakes grip onto to stop or slow your car.

These pads utilize friction to bring a halt to your vehicle when gripping onto the brake rotors. These pads grip onto the brake rotor and squeeze it until the vehicle stops and slows down to a halt.

While it may seem like a fairly simple process, any loss in grip or contact can be deadly.

Brake pads are made up of metal materials that are designed to be resistant to wearing and stop a car thousands of times before degrading.

Think of brake pads like your hand gripping a frisbee to stop it flying like a brake rotor is stopped by the pad.

Brake pads come on all shapes and sizes depending on whether you’re on a racetrack or a highway and vary greatly in function.

Most standard cars or trucks have brakes that are meant for comfortable braking and long-term durability.

To understand more about brake pads, some of the types of brake pads you may be buying will be discussed.

Types of brake pads

Depending on your driving style and car type, the brake pads you prefer may vary greatly.

Deciding which type of brake pads you want can also be influenced by a budget which also varies greatly.

To decide which brake pads may be best for you, some of the best options in their class will be covered.

  • Semi-Metallic Pads: The most common brake pads in standard cars, semi-metallic pads offer traits that make them effective for most cars. These pads are composed of either steel, graphite, or copper and additional friction components to make up the brake pad interior. These brake pads contain around 50% metal on average and utilize friction modifiers to make up the other half for braking. While these pads work in most situations, they tend to be louder, wear quickly, and don’t work well when cold.
  • Ceramic Pads: While still containing some metal, these brake pads are composed of mostly ceramic fibers and friction components. Generally found on higher-end cars, ceramic pads last longer and are less noisy than other forms due to their advanced composition. With their advanced composition and effectiveness, these pads cost much more than the other variations, but the benefits are significant.
  • Low-Metallic Non-Asbestos Organic Pads: Like the semi-metallic brake pads, these pads contain less metal at an average of 20% metal per pad. These pads can also contain the same steel or copper elements as the semi-metallic pads to perform similarly. However, these pads brake better and transfer heat much better than the semi-metallic pads, but still make noise and dust.
  • Non-Asbestos Organic Pads: These unique pads are composed of fibers, filler material, and high-temperature resins. They are considered organic and can be listed as NAO due to their natural fiber composition. Unlike the metallic pads, they are softer and less noisy but break down faster due to the fiber’s weakness.

Why are brake pads important?

While it may seem obvious why brakes are important, understanding why the pads are important is key.

While getting new brake pads seems like just another expense at the dealership, but without them, you could crash. Without brake pads, the heat generated trying to grip the rotor would cause enough heat to cause serious damage.

As cars drive around the day, every stop sign is another wear on the brake pads that makes them less effective.

Despite thinking your car can go without new pads, remaining cautious can save you from serious issues in the future.

How long do brake pads last?

While it is hard to determine the exact lifetime of a brake pad, a general estimate can be made. With such a variety of commuting conditions finding a true lifespan varies from car to car.

On average, most standard brake pads last between 25,000-50,000 miles.

This number is so varied due to the different driving styles and conditions that different drivers face.

For example, someone who commutes every day will have to replace their brake pads much more frequently than someone who works from home.

Driving style and habits such as speeding and heavy braking also have the ability to affect the longevity of your brakes.

To ensure you are staying safe on the road make sure to remember how many miles you have driven on your current and new brakes.

How do I know if my brake pads are worn out?

With an understanding of how brake pads work and wear, knowing if yours are worn out is very important.

With no perfect indicator determining pad longevity, there are a few factors that indicate your pads need a replacement.

By understanding what to look for you will be able to practice safe driving and safe braking.

  • Warning lights: With many modern cars, they will have a feature that can signal when your brake pads need to be changed. The lights may come on earlier or later than the actual life of the brakes, but they should provide accurate data. When getting your brakes checked at the garage make sure that the lights are reset and working to warn you down the road.
  • Strange noises: Usually the first thing one notices, hearing any noise when braking should be a warning sign. Brake pads are designed to make noise when they get deteriorated to a certain point. If the noise persists for a while, then you should take your car to get the brakes checked and likely replaced. If the noise only happens every now and then it is probably a result of weather or road conditions that create dust and residue on the brakes.
  • Visual wear: Contrary to what a mechanic may tell you, you can check the lifespan of your brakes visually. If you look at your brake housing between your wheels you can see how much material is left on your brakes. If you see very little material left on your brake pads and you haven’t had a service recently then get it seen soon.
  • Grinding metal: Like hearing a screeching from the brakes, hearing grinding metal is even worse. If you can hear a distinctive and low metal scrape, your pads as week as your brake rotor could be damaged. This issue can be much more serious as having a damaged brake rotor could require a whole new brake system.

What causes brake pads to wear quickly? 

After discussing the life span and function of brake pads, understanding how they break down can help improve their lifespan.

With many factors improving and worsening the life expectancy of brake pads, driving to save your breaks also saves money.

By resolving the following issues, you will be able to drive better and keep your brake pads longer.

  • Driving style: Breaking speed limits and slamming on brakes is not only a danger to yourself and others but destroys your brakes. Learning to slowly apply the brakes and drive within the speed limit will save you trips to the garage and hospital.
  • Lower the weight: If you drive a truck or large car with a heavy cargo load then your breaks will wear faster. The increased pressure on your brakes trying to stop a vehicle with heavy cargo can seriously decrease their longevity. If you generally travel with excess cargo in your truck or car removing it will save your brakes some strain.
  • Brake fluid: As a result of high miles or aggressive driving, the fluid that controls your breaks can accumulate bubbles with time. If your brake fluid is low or contaminated it can affect the effectiveness and usability of your brakes. By getting your brake fluid flushed or changed every 30,000 miles you can ensure safe braking for many miles.

What happens with bad brakes?

Choosing to go without a brake change can cause several consequences that end up causing damage or an accident. While it may save some money from the replacement, it could cost you your life if you let it go too far.

By understanding the issues that arise with bad brakes you can realize what’s at stake by forgoing the change.

  • Rotor Damage: With the brake pads and rotors being in constant connection, ensuring that one does not damage the other is essential. As your brake pads wear, the rotor will become damaged due to the metal to metal contact from thin pads. With significant rotor damage, you could need new rotors and brake pads which can cost thousands if not addressed quickly. Signs that there is contact between metal and metal is fairly recognizable by the annoying sound of metal scraping together. Not all brake rotors wear at the same rate so you could ask your mechanic about your specific brake rotors.
  • Caliper Damage: Alongside the issue of damaging your rotors and brake pads, the calipers that hold them are also prone to damage. Brake calipers send the signal from your brake pedal to your brakes and controls braking intensity when to apply pressure. Not taking your car to a garage with issues in braking and strange sounds, your calipers could be failing. Another common sign that is also breezed off is leaking brake fluid which can just often be misinterpreted as water. Generally, one caliper is damaged and can have noticeable effects on driving so if you notice imbalances seek help.
  • Brake Failure: The worst fear of many drivers, total brake failure can occur suddenly and end in a crash or even worse. Depending on the condition of your pads, calipers, and rotors, brake failure can occur when any one of them fails. Reacting at the moment is hard, but if you don’t have abs, pump the brakes to build up the fluid. Failure usually results from fluid loss and the cause comes from a leak that could have been prevented with service. Going down the gear and using the handbrake is all you can do to prevent an accident if your brakes fail.
  • Fire: Unlikely but deadly, a car’s brakes can spontaneously catch fire if excessive braking is used or pads are misaligned. Generally seen on race cars, a brake system can catch fire if you are aggressively braking with worn brake pads. The wear on brakes used aggressively occurs more quickly and often results in more serious consequences than lightly used brakes. Even if the brakes don’t fully catch on fire, the exposure to high heat can seriously damage the internal components. Fire can also be caused if excessive debris is stuck between your brake pads and rotors.

With many car drivers not having much understanding about cars, understanding brakes is not common knowledge.

However, with just a little reading and research, understanding everything about your brakes and brake pads can be simple.


With brakes often being overlooked and neglected by most car owners, understanding their importance can save you stress and money.

Understanding what types of brakes you have and how to use them properly will allow you to brake effectively.

Going to the garage and asking a mechanic about your specific car and brakes will provide professional answers and estimates.

In the end, keeping up with your services and driving style will end up saving your brakes and your life.
