The unpredictable consequences when car brakes make 'squeaking' noises

Used quite commonly in modern cars, disc brakes possess many outstanding features compared to other brake systems. However, over a long period of use, car owners will encounter many cases of damaged car disc brakes that cause danger when operating. By recognizing these problems early, car owners can proactively prevent and repair them in time.

Car brakes make noise

Damaged car disc brakes can cause a variety of noises. If you hear a regular “squealing” sound when you apply the brakes, it means the brake pads are worn and need to be replaced immediately.

If the noise is not loud or continuous, the brake mechanism may have dirt or debris in it. In addition, poor quality brake pads can also cause noise when braking.

To reduce the noise of disc brakes, car owners can apply a thin layer of special noise-reducing glue or grease to the back of the brake pads. At the same time, the brake mechanism should be cleaned immediately to ensure safe use of the vehicle brakes.

Fan blades are warped, rusted, or worn unevenly

When the temperature is too high, the rotor blades can warp. This is one of the common conditions of car disc brake damage. This condition causes the steering wheel to shake, which is easily noticed when braking at high speeds.

In addition, when the vehicle is not used for many days, the parts of the fan blades rust, leading to uneven wear of the rotor. This is the cause of vibration in the steering wheel and vibration in the brake pedal when braking at high speed.

In case of damaged brake pads, warped or unevenly worn rotors, the vehicle owner needs to replace or repair them immediately to ensure safety when driving.

Brake caliper or pad stuck

Without regular maintenance, the brake calipers and brake pads can become stuck inside the steering rack or inside the rack mount. Symptoms of this condition include a squealing noise when driving, one of the wheels overheating, or excessive brake dust.

In some cars, the rear brake caliper may stick or jam, preventing the parking brake from fully releasing. If the owner detects this problem early and has it serviced, the brake caliper can be restored to full function. However, in some cases, the owner will need to replace the steering rack for the brake system to function properly.

The above damages to car disc brakes will directly affect the safety of the driver. Therefore, car owners need to regularly maintain their cars at the warranty and repair center and detect them early to promptly fix them, ensuring safety on all roads.
