Did you want to know the causes of noise when braking at low speed? If you want to know, then you need to read this informative article to the end.
Brakes are crucial parts of all vehicles. It is very important to handle any engine problems that come, it can lead to brake problems that are even more critical because they determine whether your car stops.
A hydraulic system is a method that is used to manage the brake at all corners of your vehicle. This will be a disc brake but sometimes a drum brake.
When you press the brake pedal, the front wheel brakes have a bigger role in slowing down the vehicle than the rear wheel brakes because the weight of the car pushes forward when you apply the brakes.
There are several sounds and vehicle feedback while driving. These are the first things we notice when there’s a problem with our cars. Brake problems are one of them. So what does it mean when you begin to hear any grinding, squealing, or scraping noise when braking or feel a vibration?
Immediately you begin to hear any sound like grinding, rubbing, squealing, or metal scraping sound while driving and applying the brakes, then you should know that there’s a problem.
Common Causes of Grinding Noise & Vibration When Braking
There are several causes of noise when barking up low speed.
1. Bad Quality Brake Pads
It is very important to invest your money in high-quality brake pads. Don’t save money when it comes to purchasing brake pads. It is also important to buy your brake pads from the right store
Poor quality brake pads are completely different from good brake pads, several cheap brake pads are poorly made, and they are not good for the car because they cause serious injuries.
Cheap brake pads are properly manufactured and can have defects like metal chunks in the pad material which can scrape against the rotor and cause severe damage.
You can buy any of the high-quality brake pads brands including Akebono, Stoptech, Wagner, EBC, Powerstop, and AC Delco.
2. Worn Brake Pads
If you begin to hear a grinding sound immediately after you step on the brake pedal, then your brake pads may have worn out. As the backing plate loses its material, this allows the metal to come into contact with the metal on the rotor.
Your brakes could become damaged if the pads are not replaced immediately. Your rotor can also be destroyed by the backing plate, resulting in damage and grooves. The rotor can do the same thing to the caliper. When your brake pads are bad, you need to get them replaced immediately before it causes severe damage to other parts of your vehicle.
3. Debris Stuck in Brakes
Your brake system may have debris from the outside get lodged in it. This debris may have several things including pieces of rock or gravel that can get stuck in the caliper.
The debris will rest between the rotor and caliper, this will cause scraping or grinding noises to occur and vibration.
You’ll begin to hear these noises, even if you don’t apply pressure to the brake pedal.
If the piece that’s lodged in there is not removed, your rotor will get damaged and you may need to replace it.
Something stuck in your brakes can cause your brake pads to get out of alignment or cause uneven pad wear which will reduce your performance.
4. Infrequent Driving
Currently, a set of brake pads will last from 30,000 to 70,000 miles of normal driving depending on the type of vehicle and your driving style. But if you begin to have braking problems before this period, then you may not be driving your vehicle enough.
If the rotors don’t get used for a long time, especially if you stored your car, then rust will form on them or they may even get slightly corroded.
Other parts of the brake system can also develop rust so then you may have several issues like your calipers sticking.
Due to the surface rust, the rotor will not be as smooth as it should be and can even have slightly raised areas where the rust forms, you will be hearing bad noises from your brakes while driving or braking.
To avoid this problem, make sure you don’t store your car for a long time, and always drive it at least twice a week. If you are not using it at the moment.
Make sure you clean it regularly so that you will be able to avoid rust, in case you notice a bit of rust in any part of your vehicle.
5. Worn Brake Rotors
If you have bad brake rotors (warped, gouged, or cracked), they will begin to make a lot of bad and strange sounds. Rotors that are warped or not flat will cause squealing or squeaking noises. If the rotors are worn, there may be scraping noises instead.
In this case, worn rotors will create vibration from the braking system. The vibrations may come in several patterns and you will be able to feel them through the brake pedal or your steering wheel will shake.
In some cases, your rotors can be resurfaced (or turned) if they are slightly warped but if they have passed their lifespan, then you need to replace them immediately.
6. Worn Shims
Whenever you have time you get a brake job done or replace your brake pads by yourself, make sure you replace the shims. Some bad mechanics avoid this if they want to do their job quickly, so you need to replace them.
Always replace your brake shims regularly because if you don’t they may get worn down. This can often result in a piece of the brake shim making contact with the rotor or other metal part of the car brake.
When metal begins to touch other metals like this, you will begin to hear bad sounds from your braking system as you drive the vehicle. That’s why you need to replace the shims.
