What are the solutions for clunking noises from brake calipers?

Solutions for clunking noises from brake calipers: 1. Secure bundling with sturdy cable ties: However, the bundling force should neither be too loose nor too tight (moderate is ideal), otherwise it won't effectively resolve the noise issue. 2. Applying grease to the fixing pin: This increases its overall diameter, thereby reducing the gap between the fixing pin and its sheath. However, this method is only effective for a short time, as the adhesion of grease isn't as strong as one might expect. 3. Replacing with a new fixing pin: Before purchasing, be sure to measure the dimensions accurately with a vernier caliper to avoid mismatched clearance data. 4. Directly visiting a 4S shop for repairs: This can completely eliminate the noise.

Last time my car's brake caliper was rattling, which was really annoying. I found a free day to check it myself: removed the wheel, inspected the brake pads and caliper area for dust or rust buildup, especially on the slide rails. After cleaning off the rust, I applied high-temperature grease evenly—must choose durable silicone grease to avoid damaging seals with regular oil. If the caliper piston is stuck and can't push the brake pads, the noise will become more frequent; then it needs cleaning or replacing caliper components. It's recommended to clean the wheel hub area every six months, as rust and corrosion are more likely after humid weather. If DIY isn't your thing, head straight to a repair shop for a professional inspection to prevent brake performance issues and accidents. Ignoring such noises can damage the brake rotors over time, costing more money and posing risks.

Don't delay dealing with brake caliper noise—it's an alarm signal from your braking system. From my experience, it's often caused by dry slide rails or debris stuck inside. Try cleaning the dust with a brush and applying anti-seize lubricant to improve friction. If the piston movement isn't smooth, it might be due to rust or wear, requiring a full inspection by a technician. Pay attention to braking performance during daily drives, like gently pressing the brake at traffic lights to listen for sound changes. When washing your car, avoid spraying water into caliper gaps to prevent rust from moisture buildup. Most importantly, prioritize safety—if the noise worsens, stop driving immediately and send it for repairs to avoid more severe failures.

To deal with clunking calipers, start by cleaning the slide rails. Here's what I did: remove the wheel and brake pads, clean off accumulated dust and rust, then apply a dedicated lubricant evenly. After reassembly, test driving usually quiets things down. But don't choose lubricants randomly—low-quality oils can accelerate aging. If noise persists after cleaning, caliper components might be damaged, requiring replacement at a repair shop. Remember to check for even brake pad wear to prevent worsening issues. These simple steps can handle most situations yourself.
