Why Does It Sound Like Grinding When I Brake?

Your brakes grind may be for a variety of reasons, but no matter what the reason is, it’s always important to have the problem resolved as soon as possible to avoid vehicle damage.

The following are a few situations where your brakes make a grinding noise and what you can do to fix them.

1. Brakes Grinding When Driving

Brakes Grinding When Driving

When driving at a constant speed, you may hear your brakes grinding. There is a possibility that rocks and debris will lodge between the caliper and the rotor, causing this.

In such a situation, it’s important to remove debris from the system as soon as possible. In most cases, this problem can be fixed easily. The brake system and other performance parts could be severely damaged if you don’t act quickly.

Even if you have some experience working with cars, you should never attempt to remove rocks or debris yourself.

You can quickly fix the problem by scheduling an appointment with a dependable dealership and telling the service professional that your brakes are grinding while you drive.

Then, take your vehicle to a mechanic so that any debris on the brakes can be removed. As soon as that’s done, the grinding sound should disappear.

2. Brakes Grinding When Stopping Suddenly

Brakes Grinding When Stopping Suddenly

When you suddenly slam on your brakes, your brakes can also create a grinding noise. When you slam on the brakes in a panic-stop situation, the brake pedal rumbles, and you hear a grinding noise.

Nevertheless, if your brake pads are sufficiently thick, this shouldn’t be a problem. It may be your Anti-Lock Braking System (ABS) that is causing the grinding sound when you suddenly stop.

If the vehicle comes to a sudden halt, the ABS automatically activates and prevents wheel lockups and skidding. As a result of pumping the brakes, the grinding noise and rumbling pedal are caused by the system’s efforts to provide stability and control.

The grinding should stop once you take your foot off the accelerator or stop the car. It might signify wearing brake pads if your brakes grind constantly. The best thing you can do is schedule a brake repair as soon as possible.

3. Brake Grinding When You Press On Your Brakes

The brake pads on your car are probably not thick enough if your brakes grind when you slow down. It is crucial that your brake pads are thick enough for effective braking and to provide adequate stopping power. 

You will inevitably have to replace your brake pads as you use them over time. You will hear a screech each time you release the brake pedal if your brake pads are thinner than recommended. 

When brake pads are rubbing, this is known as brake scrubbing and signifies that they need to be replaced. Leaving the brakes on will cause the brake pads to wear out, and the squealing sound will become a grinding sound.

You’re likely scratching the brake disc and caliper when you decelerate if your brakes make a sharp grinding sound. It is most often audible when your vehicle comes to a complete stop, but it may also be audible as you step on the brake pedal. 

Ideally, you should have your brake pads replaced as soon as possible, but it may also be necessary to replace your discs and rotors at this stage.

Other Reasons Why Your Brakes are Grinding

When braking, a sound called brake grinding occurs as the brake caliper and brake disc come together. Typically, the brake grinding sound occurs when you step on the brake pedal. You may hear grinding noises coming from your brake pedals for several reasons:

Your Vehicle Might Have a Faulty Wheel Bearing

Your Vehicle Might Have a Faulty Wheel Bearing

Wheel bearings make it possible to spin your tires without excessive heat. It is possible for your wheel bearings to make a grinding noise when one or more bearings wear out and debris gets inside.

Wheel bearings that aren’t working properly can cause the following symptoms:

  • The intensity of vibrations in the steering wheel increases and then decreases
  • Wearing your tires unevenly.

Wheel bearings are typically serviced at intervals between 75,000 and 100,000 miles, so wheel bearing problems are rare.

Your Brake Rotor Needs a Replacement

For your vehicle to slow, the brake rotors squeeze the calipers against the shiny discs. Rotors so low to the ground can become rusted or constrained due to dirt and water entering.

The cause of squeaky brakes can be non-flat brake rotor discs, as opposed to worn-out brake rotor discs that produce a disconcerting shriek through the steering column. 

In addition, you can physically feel the brake pedal and driveshaft vibrating when you brake when you have a worn-out rotor.

Your Brake Pads Are Worn

Worn brake pads cause most brake grinding problems. Copper, graphite, and brass are the most common components in brake pads.

The brake pad will eventually wear away, and the metal backing plate beneath the pad will rub against the brake rotor once the brake pad has worn down to nothing. 

You will frequently hear squealing noises from your brake pads before you hear any grinding noises. Screeching sounds are also known as brake scrubbing and indicate that brake pads need to be changed.

If you do not replace your brake pads quickly, the squealing will become grinding. Ensure that you check your brakes regularly as the shoes wear away and cause the brakes to squeal.

In addition to squeaking, brake dust buildup may cause screeching noises. It is most likely that your brake pads are covered with dirt or alloying elements if your brakes are screeching but working accurately.

Brake pads have a relatively long lifespan, but brakes will fail if they aren’t replaced within 25,000 to 60,000 miles.

Something’s Lodged In Your Caliper

It could mean you have something lodged in your brake caliper if you hear constant screeching or grinding noises, even when you aren’t braking. The object can be anything as small as a stone, gravel, or pebble.

If a foreign item remains in the brake system, the brake discs will likely suffer severe damage. It is possible to try and fix the situation yourself by rapidly moving your vehicle backward and forwards in a safe area repeatedly.

Nonetheless, if this doesn’t work, you should get a professional mechanic to inspect it right away.

Are Grinding Brakes Dangerous?

There is no doubt that driving with grinding or squeaky brakes is dangerous and can lead to brake failure. Grinding brakes can damage your vehicle, but they may also be slow to respond.

If you suspect your brake pads are worn out, you should pay attention to the response time. It may feel like you’re pushing harder on the brake pedal when you drive with glazed brakes to stop.

If your vehicle has disc brakes, worn brake pads can lead to longer stopping distances, slipping brakes, and pulling your vehicle to one side.

This condition occurs when the brake rotor is not engaged or disengaged properly. As the brake pads cannot grip both sides uniformly, your vehicle pulls more towards one side. Aside from that, driving with worn brake pads or faulty brakes can cause your tires to wear out faster.

You might have to brake harder to slow down your vehicle if your brakes are compromised. You can eventually wear out your tires more quickly or unevenly if you brake heavily enough.

Can I Prevent My Brakes Grinding?

What’s causing the grinding noises will determine what needs to be done. The easiest way to avoid grinding noises is to ensure your brakes are lubricated regularly, make sure nothing is lodged in your brakes, and drive your car regularly.

In the meantime, you can’t do much if the grinding sounds are caused by regular wear and tear. Common wear items such as brake pads are expected to wear out over time.

When Should I Have My Brakes Checked?

Your brake system should be inspected every six months, ideally. Rotating your tires is a great way to remember to check them.

Keeping up with your brake maintenance is essential if you can’t recall when you last had them checked. Installing a new set of quality brake pads can make a world of difference and help prevent brake problems in the future.

Final Words

There is a relatively common issue with grinding brakes. Brake pads wearing thin is the most likely cause of grinding brakes. Fortunately, you can’t do much about it, but it does happen over time.

If you notice your brakes grinding, book an appointment with a professional mechanic immediately. The easiest way to fix a grinding brake system is to get it checked out by a mechanic. You’ll have to pinpoint the exact problem before fixing it since there are many different reasons for this.
