Is there a reason why the brake makes a loud noise? What causes the brake to vibrate ?
The brake system is one the most important components of any vehicle. It’s important to address any engine problems, but it’s also essential to understand if your car stops when you press the brake pedal. This is why brake components must be regularly checked and maintenance should not be stopped.
While most cars today have brake discs on all four of their wheels, there are some vehicles that only have drum front and rear wheels. The front wheels are more important than the rear because of the vehicle’s weight. Rear brakes wear faster than front brakes, and can fail more often.
Brakes can cause noise and vibration
Normaly, the brake pedal should feel smooth when the car is slowing down. You should hear a variety of sounds while driving to indicate a problem. Most brake system problems can be detected while driving. You should be able to hear or feel any unusual noises, such as rubbing, scraping, humming, or squeaking while braking. The sound might disappear and then return to normal. If the sound persists and becomes more severe, it could be a problem with the brakes.
The most common reasons for vibrations and noise during braking are:
1. Brake pads
Worn brake pad are the main cause of brake system noises. Brake pads that are used regularly wear down over time and the backing plate’s metallic part is exposed. The metal scrapes against the brake disc and causes a squeaking or scraping sound. Wearing worn pads while driving can lead to disc surface warping and damage, which will increase repair costs.
2. Use poor quality brake pads
Do not try to save money by purchasing the cheapest brake pads. Bad brake pads can cause accidents and serious injuries by increasing the braking distance. Poor-quality pads not only cause poor performance but can also rub against discs, causing noises and damage. Make sure you only choose well-respected brands for brake pads.
3. Worn Brake Shims
The sound and noise reduction unit behind the brake pad is called the brake shim. It reduces vibration in brake pads, attenuates them, and acts like a thermal barrier. This ensures that pad temperatures remain consistent for braking.
The shims should be returned with the brake pads. This may be avoided by some mechanics to make the job easier. The brake shims can wear and become damaged, causing friction with the brake disc. This can lead to a variety sounds while driving or braking.
4. Brakes with Trapped Dirt or Debris
Pebbles or dirt can collect in the brake system and become lodged in the caliper. Small stones stuck between the disc and the caliper could cause vibrations, scraping and rubbing noises. These sounds can be heard even when you don’t press the brake pedal. The brake disc could be damaged if the object isn’t removed. Turning the brake disc is the best option.
Uneven wear can result from something getting stuck in your brakes. This can lead to a decrease in performance and the need for replacement of the pads earlier than usual.
5. Very rare driving
Depending on your vehicle type and driving habits, brake pads typically last between 50,000- 100,000 kilometers. There are many brake problems that can occur if your vehicle is not driven often. Rust can cause damage to the pads and discs of cars if they aren’t used for a while. Other parts of your brake system may also rust. This can cause problems such as stuck calipers. Because of the rust, discs become curved in areas where it has formed. You may hear strange sounds while driving or braking.
It is best to use your vehicle only occasionally and not leave it unattended for too long. A small amount of rust may be removed by brake, friction, or heat. If the discs or calipers are damaged, they may need to replaced.
6. Warping of brake discs
Broken or worn brake discs can make a variety noises, including crackling, warping, or pitting. In extreme cases, uneven or curved discs can cause friction noises and squeaking during braking. Additionally, curved discs cause a lot vibration in the brake system. The brake pedal and steering wheel may be able to detect vibrations that are intermittently noticeable. This can sometimes be fixed by turning the brake discs. However, if an expired disc is found, it must be replaced.
7. Leaning Brake Components
Before replacing your brake pads, you should lightly oil the rear with brake caliper oils. This simple step should be taken seriously. If you don’t, you may hear a squeaking sound or rubbing sound when applying the brakes. Before you reinstall the brake caliper, make sure the slide pins connecting the brake caliper to the other side are well lubricated. Also, grease should be applied to the brake caliper bolts. Dry slides can cause them to make noises. Although this is unlikely, it shouldn’t be ruled out by a skilled mechanic.
8. Balls for Defective Wheels
This is most likely to be the cause of your brake noises. The problem may be with your wheel balls if you experience grinding sounds from your wheels, or vibrations that vary from loud to very quiet. You may also feel vibrations while driving.
