Rattle when braking. The main causes of squeaking brakes

The problem of rattle when braking from time to time concerns every motorist. Still – a lingering whistle when braking, scares and alarms. But is it always necessary to immediately go to the nearest service or even call a tow truck for this? In most cases, yes. The creaking of brakes (pads) is in any case a true signal about the malfunction of one of the most critical components of the car, directly related to your safety. Let’s try to make out four main reasons – why do the brakes squeak on the car?

The brakes creak not only when braking, but also during the drive.

The brake pads are equipped with special metal “surface”, when the surface of the pads is erased during operation, the bracket for brake pad touches the disc and an unpleasant grinding of the brakes occurs. This is done on purpose – for a reliable indication that it is time to replace the pads. In addition, some cars have a special sensor – a warning light, and if necessary, replace the brake pads it lights up.

How to check that the brakes creak due to wear?

If your car has disc brakes, you can simply try to turn the steering wheel all the way to the side and shine a flashlight on the block, you can determine the thickness of the block “by eye”. If the thickness is more than decent, and the brakes creak when moving, you need to immediately contact the service station. If it seems difficult for you to determine the thickness of the pads on the “eye”, immediately contact the nearest service for checking the wear of the pads.

The thickness of the pads is easily determined by just taking a look at it.

The creaking of the brakes (pads) occurs due to their vibration.

When braking, a strong vibration is naturally created in the area of ​​action of the pads and brake disc, and squeaks and even prolonged “squeals” occur. Usually, in order to avoid extraneous sounds, a special “anti-creak” vibration-absorbing plate is installed between the block and the caliper piston. It happens that in some service stations that are not entirely clean, such gaskets are simply lost or especially thrown away so that the client would rather come to them with a new problem – the whistle of the brakes and change almost new pads.

Drove into the dirt and the pads began to creak!

Another classic problem, the grinding of brakes – liquid mud or clay, hitting the working surface of the brake pads, dries out and makes terrible sounds – from a creak to a long howl! Therefore, if you encountered a squeaking problem after a road trip (you left the federal highway for the local road somewhere in the outback). It is necessary to remove the wheel, rinse it well, clean the caliper and brake system elements (except for the friction surface) with a metal brush, and then use a special tool to clean the brake discs.
