Got Grinding Brakes? Here’s How to Fix Them

got grinding brakes here’s how to fix them

Grinding brakes can be a frustrating and concerning issue for any driver. The high-pitched noise can be alarming, and it’s important to address the issue promptly to avoid further damage to your vehicle. Fortunately, fixing grinding brakes is a relatively straightforward process that can be done at home or by a professional mechanic.

The most common cause of grinding brakes is worn brake pads. Over time, the friction-reducing material on the pads wears down, causing metal to grind against metal. Other potential causes include faulty wheel bearings, rusted or warped brake rotors, low-quality brake pads, lack of lubrication, or debris lodged in the brake caliper. It’s important to have a mechanic inspect your brakes when you notice any grinding noises to avoid further damage and ensure your safety on the road.

In this article, we’ll explore some simple explanations for fixing grinding brakes and provide tips for preventing the issue from arising in the future.

Diagnosing the Problem

Identifying the Symptoms

When brakes start grinding, it’s a clear sign that something is wrong. The grinding noise is usually caused by worn brake pads or rotors. However, there are other symptoms that can indicate a problem with the brakes. These symptoms include:

  • Squeaking or squealing noise when braking
  • Soft or spongy brake pedal
  • Vibrations when braking
  • Pulling to one side when braking

Checking the Brake Pads

The first step in diagnosing the problem is to check the brake pads. Worn brake pads are the most common cause of grinding brakes. To check the brake pads, follow these steps:

  1. Park the vehicle on a level surface and engage the parking brake.
  2. Remove the wheel and inspect the brake pads.
  3. Look for signs of wear and tear, such as cracks, grooves, or uneven wear.
  4. Measure the thickness of the brake pads. If they are less than 1/4 inch thick, they need to be replaced.

Inspecting the Rotors

If the brake pads are not the problem, the next step is to inspect the rotors. Worn or damaged rotors can also cause grinding brakes. To inspect the rotors, follow these steps:

  1. Look for signs of wear and tear, such as grooves, cracks, or uneven wear.
  2. Measure the thickness of the rotors. If they are less than the minimum thickness specified by the manufacturer, they need to be replaced.
  3. Check the rotor surface for rust or corrosion. Rust can cause uneven wear and lead to brake noise.

Fixing the Brakes

When it comes to fixing grinding brakes, there are a few options available. Depending on the severity of the issue, the solution may be as simple as replacing the brake pads or as complex as replacing the rotors. Here are the three main options for fixing grinding brakes:

Replacing the Brake Pads

One of the most common reasons for grinding brakes is worn brake pads. Brake pads are made of a friction-reducing material that wears down over time. When the pads become too thin, the metal backing plate will come into contact with the rotor, causing a grinding noise.

To replace the brake pads, the wheel must be removed, and the caliper must be unbolted. The old pads can then be removed, and the new ones can be installed. It’s important to use high-quality brake pads to ensure optimal performance and longevity.

Resurfacing the Rotors

If the brake pads have been worn down for an extended period, they may have caused damage to the rotors. In this case, resurfacing the rotors may be necessary. Resurfacing involves removing a thin layer of metal from the rotor’s surface to create a smooth, even surface.

Resurfacing can only be done if the rotors are thick enough to allow for the removal of metal. If the rotors are too thin, they will need to be replaced.

Replacing the Rotors

If the rotors are too thin to be resurfaced or have been damaged beyond repair, they will need to be replaced. This is a more complex and expensive process than replacing the brake pads.

To replace the rotors, the wheel, caliper, and old rotor must be removed. The new rotor can then be installed, and the caliper and wheel can be reattached.

Preventing Future Problems

Regular Maintenance

To prevent future problems with your brakes, it’s important to perform regular maintenance. This includes checking the brake pads for wear and tear, inspecting the rotors for damage, and ensuring that the brake fluid is at the recommended level. A reliable way to do this is to use a brake cleaner once per month and give them a good scrubbing. If they do develop rusting issues, though, there’s a good chance they cause a grinding sound.

Upgrading the Brake System

If you’re looking for a more long-term solution, upgrading your brake system is a good idea. This can include replacing the brake pads with high-performance ones, installing larger rotors, or upgrading the brake calipers. Upgrading your brake system can improve your car’s stopping power, reduce brake fade, and increase the lifespan of your brakes.

Before upgrading your brake system, it’s important to research the options available and choose a reputable brand. It’s also important to ensure that the upgraded parts are compatible with your car’s make and model.


So, grinding brakes can be a frustrating and concerning issue for any driver. However, it is important to address the issue promptly to avoid further damage to the vehicle and ensure safety on the road.

The most common cause of grinding brakes is worn brake pads, which can be easily replaced by a professional mechanic or a knowledgeable DIYer. Other causes, such as rusted or contorted brake rotors and faulty wheel bearings, may require more extensive repairs and should be addressed as soon as possible.

Regular maintenance, such as using a brake cleaner and having brakes inspected regularly, can help prevent grinding brakes from occurring in the first place. It is also important to pay attention to any unusual sounds or sensations while driving and address them promptly.

Overall, addressing grinding brakes is a simple fix that can save drivers time, money, and potential safety hazards. By following basic maintenance and addressing any issues promptly, drivers can ensure their brakes are functioning properly and enjoy a safe and comfortable driving experience.


Can I just replace the brake pads and not the rotors?

Yes, it is possible to replace just the brake pads and not the rotors. However, it is important to note that if the rotors are worn or damaged, replacing just the brake pads may not solve the grinding noise issue. In some cases, it may be more cost-effective to replace both the brake pads and rotors at the same time.

How often should I replace my brake pads?

The frequency with which you need to replace your brake pads depends on a variety of factors, including your driving habits, the type of vehicle you have, and the quality of the brake pads you use. Generally, you should replace your brake pads every 50,000 miles or so, but it’s important to have them inspected regularly to ensure they are in good condition.

Can I use any type of brake pads on my vehicle?

No, you cannot use any type of brake pads on your vehicle. Different vehicles require different types of brake pads, and using the wrong type can cause serious damage to your brakes and your car. It’s important to consult your vehicle’s owner’s manual or a trusted mechanic to determine which type of brake pads are best for your vehicle.

How can I tell if my rotors need to be replaced?

There are a few signs that your rotors may need to be replaced, including a pulsing or vibrating sensation when you apply the brakes, a squealing or grinding noise when you brake, or visible damage to the rotors themselves. If you suspect your rotors need to be replaced, it’s important to have them inspected by a professional mechanic as soon as possible.

Can I fix grinding brakes myself?

It is possible to fix grinding brakes yourself, but it’s important to have the right tools and knowledge to do so safely and effectively. If you are not confident in your abilities or don’t have the necessary tools, it’s best to leave the job to a professional mechanic.
