New brakes create a grinding noise at low speeds for a reason.
Brake noise might be bothersome, but it can also be a lifesaver since it warns us when our automobile brakes are failing. We’ll look at ten common reasons of brake grinding sounds while braking but pads are good in this post.
We’ll also investigate the most common cause of brakes grinding at low speeds. Why are you hearing grinding noises from your new brakes at low speeds? Finally, I’ll respond to the question “how long can you drive on grinding brakes?”
While your automobile produces grinding sounds when braking, it’s a warning indication that something is wrong with the brakes or the rotors. For fear of high repair costs, never ignore your car’s braking sounds.
If you wait to address the problem and continue to drive the automobile, it may end up costing a lot of money to fix, which you might have avoided if you had examined it sooner.

When the brake pads are fine, there are ten causes of grinding noise.
A vehicle’s components cannot last indefinitely. They will wear and tear with time, but it is critical to recognize and correct issues before they degrade to a point where they are beyond repair or would cost you a lot. Now, in this part, we’ve listed the 10 most common causes of grinding noises while brake pads are in good condition.
Solids wedged between the Rotor and the Caliper are number one.
It is typical for the rotor and calliper components to collect filth, dirt, and dust. When tiny pebbles or other solid things from the road lodge between the calliper and the rotor, however, it might cause a problem. This may cause the brakes to grind whether or not you apply pressure on them. Between these components, solid objects may cause significant harm. 11 Best 4 Channel Car Amps for Sound Quality (Related Post)
2. Brake Pads That Have Been Worn Out
Worn-out brake pads are one of the reasons your automobile makes grinding noises while stopping. If you’ve had your brake pads for a long time, it’s time to replace them. Worn-out brake pads cause the backing plates to gradually lose material, resulting in metal contacting metal and squeaking sounds. The rotor may also scrape the metal surface of the caliper if it rubs against it. If left uncontrolled for an extended period of time, the brakes will get seriously damaged.
3. Rotor Discs That Have Been Worn Out
Worn-out rotor discs are another probable source of grinding sounds while braking. Rotor discs that aren’t flat may make squeaking noises. The braking system will produce scraping noises and a lot of vibrations if the rotor discs are worn out. These vibrations occur in a variety of shapes and sizes, and they may be felt via the brake pedal.
4. Brake Pads of Poor Quality
It is incorrect for you to purchase low-quality brake pads solely to save money. Metal pieces in low-quality brake pads rub and scrape against the rotor’s surface, causing substantial damage. Instead of low-quality brake pads, invest in high-quality items from a reputable manufacturer. It may be costly at first, but it will save you money in the long run by preventing costly repairs caused by bad brake pads.
5. Shims that have been broken
Another probable reason of the grinding sounds during braking is broken shims. When a worn-out shim makes contact with the rotor, the braking system will create a grinding noise. When working on your brake, make sure you or your professional replace the shims.
6. Bolts on calipers that aren’t greased
Caliper bolts that aren’t greased might also generate a grinding sound while braking. Even though this is very unlikely, it is nonetheless possible. During repairs, a car technician will have to install new caliper bolts for you.

7. You Don’t Drive Your Car Very Often
Because you haven’t driven it in a while, your automobile may be creating grinding noises while braking. Brake pads have an average lifetime of 20,000 kilometers. However, if you park your car in your garage for many weeks, the brake pads may not last as long. Rust and corrosion might harm the rotors due to inactivity and severe weather. Rust will spread to other components, causing them to fail. This may be prevented if you drive your automobile on a frequent basis.
8. Wheel Bearings That Have Failed
A worn-out or broken wheel bearing may generate grinding sounds or mild to loud vibrations from your wheels. To get rid of those grinding noises, check the wheel bearings and replace them if required.
Drum brakes (nine)
Drum brakes are used at the rear of most automobiles. Brake drums, like rotors, are refinished every now and again. The brake lathe’s cutting bit removes the old braking surface, revealing a lovely new mating surface. During this procedure, the cutting tool will create a groove in the brake drum. This furrow will be so little that it will be invisible to the human eye. The brake shoes will now follow the groove while riding on the new surface. The shoes snap back and strike the backing plate if the groove is interrupted. This results in a grating or pounding sounds.
10. Brake pad is not lubricated
When installing a brake pad, you must adequately lubricate the backside of the brake pads. You may use brake caliper lubricant to grease them. The metal of the pads and the metal of the caliper piston might rub against each other if this portion isn’t lubricated, generating grinding sounds. Before replacing the brake caliper, make sure the caliper slider pins that link the two sides of the brake caliper are lubricated.
What Happens If You Ignore Brakes That Make Grinding Noises?
When braking, you should never overlook a grinding noise since it might jeopardize your safety. When you press down on the brake pedal, the automobile generates a lot of heat energy due to friction. Though required, his actions may wear down the brake pads over time, resulting in a broken rotor and caliper, which can cause the brake to fail. If your brakes aren’t working properly and aren’t checked, it may lead to fatal accidents (s).
To prevent grinding down your rotors, you must change the brake pads. Replacing your brake pads on a regular basis helps to keep your rotors safe.
How long can you drive if your brakes are grinding?
Despite the fact that some people claim they were able to get away with driving their vehicle with grinding brakes for approximately two weeks, I would not recommend it. Avoid driving your automobile with grinding brakes as much as possible.
Driving your automobile with grinding brakes for two weeks is excessive and dangerous. You can still drive the automobile for a while if you don’t slam on the brakes too hard. However, if brake pads are the problem, it’s best to acquire a new set and have the old ones replaced as soon as you hear the grinding noises. If not, check into some of the reasons of grinding sounds while braking, but make sure your brake pads are in good shape.
Alternatively, you may get the concerns checked by a professional mechanic.

One of the most common causes of brakes grinding at low speeds is
Some people have noted that when they brake at high speeds, their automobile makes no noise, but when they come to a stop, their car makes a grinding sound. If stopping at a low speed (under 25-30 MPH) causes the grinding noise to steadily worsen until the vehicle comes to a halt, the front brake pads may need to be replaced. One of them may be entirely worn out to the backing. It’s also possible that you’ll need to replace the rotor since it’s worn out the mating surface.
Why do my new brakes produce a grinding noise while they’re not in use?
After hearing a grinding noise while braking, you may purchase new pads and rotors and have them fitted. However, a few weeks after the new installation, you may notice that the noise returns.
Your new brakes may be making grinding noises at low speeds due to the brand or kind of pads and rotors you selected. Even when fresh, several kinds of brake pads might generate a screeching or grinding noise when the brakes are applied. Metal composite material is used to make these sorts. So, before making a purchase, do some research on the brand and what to anticipate.
Symptoms of Bad Braking Pads | Symptoms of Caliper Issues
Whether your automobile is producing grinding noises or has other braking troubles, here are some symptoms to check for to determine if you should get your brakes repaired.
- The brakes are generating a grinding noise that is audible through the pedal. If this occurs, you must immediately stop driving and have your car towed to a brake repair facility. Because pushing it any farther risks damaging the pricey brake discs or drums.
- In traffic, a car goes too long before coming to a halt. This might imply that we need to tune our brakes or replace our brake linings.
- When you press the brakes, the vehicle pulls to one side of the road. For automobiles with front disc brakes, a brake fluid leak or a jammed calliper might create this issue.
- When you come to a halt in a non-emergency circumstance, the brake pedal thumps up and down. Excessive lateral run-out causes a pounding brake pedal.
- When you brake, the steering wheel rattles. If you have disc brakes and your steering wheel rattles when you brake, your front brake discs need to be changed.
- When you stop for a brief period of time, your brakes squeak. Brake linings that are worn out and need to be replaced might produce squealing.
- When you come to a sudden halt, your car bounces up and down. This indicates that your shock absorbers must be replaced.
- Your front wheels have a rusty coating on them. Disc brakes that have totally worn the pads off and are now metal on metal are the cause of rusty dust on your front wheels and a rusty spray on the front doors and fenders. Iron and steel shavings cause the rusty dust, which may cause sparks and even embed in your paint. It is quite dangerous to drive your automobile in this state.
Are the Braking System Grinding Sounds Dangerous?
Yes, if you ignore a granding sound from your car’s braking system, it may be dangerous. The braking system is in charge of your vehicle’s safety features. As a result, don’t dismiss any warning indications. If you detect any warning indications, such as a squeaky or grinding sound while braking, get your car inspected right away.
How much does it cost to replace brakes and rotors?
The cost of repairing a brake for one wheel, including new callipers, pad replacement, and new rotors, may range from $300 to $800, not counting labor. This, however, is contingent on your vehicle and other circumstances. If all of these components need to be replaced, plan on spending about $1000 or more. However, changing brakes and rotors costs roughly $500 on average.
Can I Drive My Car If My Rotors Are Damaged?
Driving with defective rotors is not recommended since they are unable to absorb and distribute heat, causing the braking system to overheat. Even if you continue to drive a vehicle with defective rotors, the brakes will become ineffective and may eventually fail, putting your and others’ safety at risk.
Finally, when the brake pads are fine, there are ten causes of grinding noise.
We looked at 10 frequent causes of grinding sounds while braking but pads are good, as well as how long you may drive on grinding brakes, one common cause of brakes grinding at low speeds, and the major reason why new brakes may generate grinding noise at low speeds in this article.

Frequently Asked Questions
Why do my brakes grind but pads good?
A: When your brake pads wear down, they will begin to lose their effectiveness. This means your brakes wont stop as well and may cause them to grind when you apply pressure. You should replace the old worn out brake pads with new ones if this is happening.
Why are my brakes still make noise after I changed them?
A: The brakes on your car are worn out and need to be replaced.
Is it normal for new brake pads and rotors to make noise?
A: Some brake pads are surface treated with an anti-vibration material, such as those found on ceramic versions. This can lead to a shhhhh noise when braking and turning so much that the rotor starts to vibrate against this treatment. The vibration noise is caused by small pieces of material rubbing together between the grooves in all three layers of metal.
