It may be a little annoying and even a bit frightening to hear a scraping noise when braking at low speed. It is a sign that your car’s braking system is not normal or something is wrong with the brakes. But what is this sound, and what if you do not pay attention to this signal? Car owners, DIYers, and mechanics should know the cause of a scraping noise when braking at low speed. It will help ensure safety and save money.
This blog is designed to explain the main reasons for grinding noise and its repercussions. If left unnoticed, there are also important questions to ask for your car to move on smoothly.
Why You Shouldn’t Ignore Scraping Noise When Braking At Low Speed?
That grinding or scraping sound whenever you apply the brake pedal is not just an annoyance. But a signal that not everything is right with your car’s braking system. Failure to do so will result in higher expenses and the most significant risk to human life.
Accelerated Brake Wear
If ignored, the grinding sound you hear could be due to your brake pads wearing more than normal. These pads wear out the brake discs for a while. They rattle against the caliper, which is a very costly replacement to carry out.
Risk of Brake Failure
Hear a scraping sound? Most of the time that is a functional problem within your braking system. If it is left unresolved, you may continue driving, risking a total brake failure. Eventually, that will endanger your life and the lives of your fellow road users.
Higher Repair Costs
An unmanaged faulty braking system can cause so many problems. it is not only a brake pad problem which then becomes a rotor or caliper problem. But also that increases both the cost and time to get the car fixed.
It isn’t only economically feasible or financially prudent if you fail to address it. Also, it has always been more advisable to act fast.
Causes of scraping noise when braking
Here are several possible causes behind the scraping noise when braking at low speed. The awareness of these could help you identify the problem. And what to do consequently, as the causes of oil spills may be attributed to any of the following:
1. Worn-Out Brake Pads
The most common reason for grinding sounds is the wear and tear of brake pads to an unbelievably bare minimum. Brake pads also have a metallic wear tab that makes contact with the brake rotor once the pad material is worn to the barest minimum. This scraping sound is intended to let you know that it is time to replace your brake pads before they go bad. The brake pads should be replaced as soon as possible. They recommended that people should monitor the thickness frequently to prevent using counterfeit products.
2. Some Amount of Debris Found Between the Brake Elements
Some dust, including pebbles, dirt, or mud, may interfere between the brake pad and rotor. One will hear a scraping sound each time while the braking.
This may be done by a simple survey of the braking system or by washing it. Even the most inexperienced person can be able to do this but is always better to get a professional to do it for you.
3. Glazed Brake Pads or Rotors
This is a condition where brake pads or rotors turn glossy and glazed. And become too smooth to bite the brake drum or the brake disc appropriately. This narrow rail width may cause a squealing or scraping sound when the brakes are applied.
You should sand down the pads or rotors if the glazing is not too bad. If they are serious, there would be a need for parts replacement. If less serious, you will need some of them replaced. Here are several possible causes behind the scraping noise when braking at low speed.

4. Damaged Brake Rotors
If your rotors are warped, scored, or damaged, they are the main cause of grinding noises. Relying on everyday wear, extreme heat or a problem with pads, the rotors may become damaged.
Look at your rotors, and if you can see the damage, repair or change them. Make sure that you have enough brake pads because these will later cause problems with your rotors.
5. Faulty Calipers
Sometimes, the piston in the caliper will stick or be partially seized. Mostly, which means that its pressure will be uneven or touching the disc and cause a scraping sound.
Make sure that it’s moving as it should when you apply pressure on the caliper’s surface. A professional mechanic may be required to service, repair or change the component.
6. Rust and Corrosion
That is why moisture collects on the rotors or the drum brakes in case the car has been parked long enough. This rust can cause noise, especially when calling on the brakes to make a halt. Some minor surface rust is usually wiped off after a few uses of the equipment. However, extensive rusting might force the rotors to be refinished or replaced.
7. Poor Installation of Brake Components
The brake parts are not very well installed during the manufacturing process of the cars. Because it is one of the most important aspects that is given less attention.
New brake pads or other components were recently installed in the wrong manner. Then they may cause a scraping sound.
Conduct an assessment of the newly replaced components for confirmation of correct installation. And then correct the errors observed.
8. Low-Quality Brake Pads
Low-cost brake pads wear out frequently or show uneven wear. They then screech as they slip on the discs or rotors. Imported brake pads are better than local ones. One should purchase them from Original Equipment Manufacturers (OEMs).
Frequently Asked Questions
Should I continue driving if my brakes make a grinding sound?
It’s not advisable. Normal braking or rather squeaking or grinding sounds are usually a sign of another problem in your braking system. Carrying on and driving could result in much harm and elevate your safety dangers. It would also be appropriate to respond to the problem as soon as possible.
What Signs Tell You That Your Brake Pad Is Due For Replacement?
This is a set of usual symptoms that indicate your brake pads are worn out: pedal low, metallic sound each time you use the brakes, your car takes more distance to stop, or you can physically see signs on the pads themselves.
Can These Scraping Sounds Be Treated DIY?
If the problem is debris, a little rust or the pads installed incorrectly, then you should be able to fix it yourself if you are well-equipped and well-trained. However, if the pads are completely worn out, or the rotors are significantly damaged, or the calipers are faulty, seek the service of a professional mechanic.
When Do I Need to Inspect My Brakes?
Basically, you should check your brake pads and rotors from time to time or during service intervals of 6,000 to 8,000 miles. This is the best prevention to avoid any scraping noise when braking at low speed.
What If You Don’t Replace Bad Brake Pads?
If you do not replace bad brake pads, then you will be damaging your rotors and/or calipers. Your car will need a much longer distance to stop and can even have a complete brake failure.
Safety comes first, so scraping sounds are not to be dismissed.
Why does a new brake scrape sound while driving?
As people know, when they fit new brakes on a vehicle, it provides enhanced performance and safety. Still, hearing a metallic scraping sound when driving with new brakes is quite worrisome, of course. This noise could be caused by the following; If the brake pads are not fitted properly, this creates noise and; If there is dirt between the brake parts, this also leads to the creation of noise.
This could be because of the normal break-in process, which involves taking new pads and rotors to bed-in and sometimes causing unusual noises. As an automobile service company and, in return, customer service, our responsibility is to serve your best interest and ensure you’re safe. It is therefore advised that one takes a professional Testimonial that these sounds are normal signs of tremendous transformation or if they are critical threats that would wish for more extensive harm.
How Long Can You Safely Drive Your Car When Your Brakes Are Grinding?
As we mentioned earlier, it may be more convenient to keep driving with grinding brakes than trying to find an auto mechanic who could fix them or spend money at the moment to get the problem solved. This is a very big NO.
As soon as you notice a squealing noise coming from the braking system, it is high time to fix it. Leaving travel for the grinding brakes can cause a lot of wear on the brake pants, and a total failure of the rotors can happen, thus resulting in a total brake system failure. As little as an hour’s driving in such conditions significantly enforces the likelihood of an accident. Returning back to our customer-centric approach, we pride ourselves on insisting that your safety should always come first and that signs of brake failure call for immediate action. As a result, it is advised to set an appointment for the inspection and repair to ensure the safety and efficiency of the car.
