How to Solve the Clicking Sound When Releasing the Brake?
4 Answers
Here are the reasons and solutions for the abnormal noise when releasing the brake: 1. Reason: This noise is mainly caused by releasing the brake too slowly when starting, which is a common issue for many automatic transmission car owners. When the brake pedal is released too slowly, the engine already has enough power to drive the car forward, but the brake is not fully released. As a result, the rotating wheels are held back by the brake system, naturally causing abnormal noise. Solution: Release the brake more quickly. 2. Reason: The brake disc and brake pads may stick together due to rust, causing noise. This often happens after driving in the rain and then leaving the car unused for several days. The brake disc and brake pads rust and stick together, leading to noise when driving again. Solution: Apply butter or specialized lubricant to the connection between the brake pads and the brake caliper at a repair shop. 3. Reason: Many brake pads nowadays are made of semi-metallic materials, containing a large number of metal fibers. Sometimes, metal particles may form, producing a harsh noise when pressing or releasing the brake. Solution: Persistent noise may indicate poor manufacturing quality. It is recommended to replace the brake pads promptly to avoid damaging the brake disc.
When I encountered a situation where there was a clunking noise upon releasing the brake, I went straight to the repair shop for a check. They found that the brake pads were worn to the limit, causing the caliper to make noise when retracting. Replacing the new brake pads solved the problem. I suggest you first take a simple look yourself: find a safe place to park, check the wheels, and see if the brake pad thickness is below 3mm; if there is rust or debris, clean it with a soft brush. Also, pay attention to whether the caliper guide pins are poorly lubricated—if they're rusty, adding some lubricant can help. Don’t ignore it, as such abnormal noises can accelerate brake disc wear and increase the risk of accidents. Regular maintenance is key to prevention—inspect the brake system every 10,000 kilometers, including the condition of the fluid and the wear of pads and discs. Remember, early action saves hassle, money, and ensures safety.
As a car owner, I immediately researched after noticing a clunking sound when releasing the brake while driving. Possible causes include deformed brake pads or caliper rebound failure. Try these DIY tips: Check for rust on brake discs when parking in the morning, especially after rainy days - lightly sanding the surface with sandpaper can remove rust adhesion. If the sound occurs frequently during low-speed starts, inspect whether the brake caliper mounting bracket is loose or if guide pins lack lubricating grease. When changing brake fluid yourself, be careful not to mix types to avoid corrosion. But if you truly can't solve it, visit a professional shop immediately; they can use tools to test caliper piston function, wheel cylinder sealing, etc. Preventive maintenance like semi-annual system checks helps reduce problems.
Don't ignore the creaking sound when releasing the brake. Last time my car had a similar issue and nearly caused an accident. Take immediate action: prioritize inspecting the brake pads and discs, as uneven wear can lead to abnormal noises; seized calipers may result from rusted guide pins or lack of lubrication, requiring greasing. Visit a repair shop for a comprehensive diagnosis, including testing the function of the wheel cylinders and master cylinder. Safety comes first—delaying repairs could lead to reduced braking power or failure.
