What Causes the Squeaking Sound in Car Brakes?
2 Answers
Reasons for squeaking car brakes: 1. Severe wear of the brake disc; 2. Hard foreign objects entering between the brake pad and brake disc; 3. Brake pad warning - when the wear reaches the warning line, an alarm sound is emitted; 4. Use of low-quality or overly hard brake pads; 5. Abnormal noise from the return spring of the brake light switch on the brake pedal. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of moving locomotives, vehicles, other transport tools, or machinery. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine and install corresponding brake shoes, bands, or discs on the machine base, which generate braking torque under external force.
Last time my car's brakes were squeaking so annoyingly. I figured out it was mainly caused by severely worn brake pads. After driving for several years without replacing them, the thickness had worn down to the limit, and the metal backing plate was directly rubbing against the brake disc, producing that harsh noise. You should also pay attention to weather effects - like after rain or car washes when it's damp, the brakes might temporarily squeak but it should go away soon. If the noise persists, you need to get it checked immediately. There could be other causes for abnormal noises too, like small stones or sand particles stuck in the brake gaps, or uneven surfaces on the brake discs. My advice is don't ignore it - go to the repair shop promptly to replace the pads. Otherwise, if you delay, the braking distance will increase, making it more dangerous.
