Why does my car's brakes squeal?
Content
A screeching noise when braking may not be a concern, but it can also be a sign of something serious. It's best to check the pads as soon as you hear your car's brakes.
The brakes, a hydraulic system, work on the basis of the pressure that is created when the brake fluid is released and presses on the pads to compress the discs. Brake pads are made up of a metallic or semi-metallic material and a type of paste that allows friction to be created on the discs when the brake is applied.
There are many elements involved in this process, and some of them may cause strange noises when braking.
Why is there a screeching sound when braking?
Screeching when braking can be alarming. However, nothing serious happens and this is not associated with a significant drop in braking efficiency.
The squeal is produced by the pads when they rub against the disc, and since the surfaces are always uneven, there is a vibration that is heard as a squeal. This usually happens more often with replacement pads whose materials differ from the original ones, and sometimes with factory ones.
On the other hand, squealing can be caused by metal-to-metal friction between the brake pads and disc. Do not underestimate this noise, because it is probably due to the wear of the linings and if you do not change them for new ones, then the brakes can run out at any time.
When the brake pads begin to fail, the car itself gives you the following signs:
- Squealing sound every time you brake.
– If you apply the brake harder than usual.
– If the vehicle vibrates the brake pedal when you press it.
– If the vehicle moves in one direction after applying the brakes.
When these symptoms are detected, it's time to buy new pads. Remember to buy quality products that work well and give you a guarantee of safe driving.
