Why is there a rubbing sound coming from the car?

This situation may be caused by friction in the braking system. Here is relevant information: 1. Introduction: The braking system consists of a control system, hydraulic system, and power assist system. 2. Working principle: The principle of the braking system is to generate enormous friction, converting the vehicle's kinetic energy into thermal energy. As we all know, energy cannot be created or destroyed, but can only be transformed from one form to another or transferred from one object to another, with the total amount of energy remaining constant during the process of transformation or transfer. During acceleration, a car converts chemical energy into thermal and kinetic energy, while during braking, the braking system converts the car's kinetic energy into thermal energy and dissipates it into the air.

I just encountered this scraping sound, it scared me! A common cause is worn brake pads, which can make noise when rubbing, especially noticeable at low speeds, indicating you might need new pads. It could also be a bad wheel bearing, making noise when rolling, which worsens at high speeds. Once, I checked and found the exhaust pipe was loose and dragging on the ground, causing continuous friction noise. Don't ignore it, as it increases braking distance and could lead to accidents in emergencies. I recommend going to a professional repair shop immediately for inspection—don't try to fix it yourself. They have the tools to pinpoint the issue. Safety first, my friend.

I've dealt with many similar cases at work. A squeaking sound usually indicates an issue with the braking system. For example, when brake pads wear thin, they can produce friction noise during braking. A faulty wheel bearing can also cause continuous noise, especially noticeable when turning. Other possibilities include loose suspension components, worn drive belts, or engine part friction. Quick diagnosis: Test with light braking at low speed – if the noise is pronounced, the brake pads likely need replacement. Regular maintenance involving cleaning and adjusting these components can prevent worsening issues. Get it checked at a professional shop ASAP.

When my car makes this kind of noise, I worry about safety. My friend said it might be the brake pads or wheel bearings acting up, and the friction sound indicates worn parts. If it happens during acceleration, perhaps the engine belt is loose. I drove straight to the repair shop for a check-up—never delay. Noise might hide serious issues, especially on rainy days when it's even more dangerous. Maintaining the car properly brings peace of mind.
