How to Solve the Problem of Brake Noise in Dongfeng Yulon?

If the brake guide pin is rusted or the lubricant is dirty causing poor return, clean the brake guide pin, polish it with fine sandpaper, and apply new lubricant. If it's an issue with the brake caliper, the brake caliper needs to be replaced, but this kind of failure is relatively rare. Below are some precautions for using brakes: 1. Avoid emergency braking at high speeds: When driving at low speeds, you can perform emergency braking in case of sudden events ahead by stepping hard on the brake pedal. However, this should not be done at high speeds to avoid vehicle skidding or rollover. 2. Gentle braking: Under normal road conditions, you can apply gentle braking. While pressing the clutch pedal, release the accelerator pedal, shift to a lower gear, and after the speed decreases, lift the clutch pedal and press the brake pedal until the vehicle stops. 3. Intermittent braking: In situations like long downhill slopes in mountainous areas or continuous braking that can easily generate high temperatures, intermittent braking by alternately pressing and releasing the brake pedal can effectively prevent the brake system from overheating.
Brake noise is really annoying, I've experienced similar issues before when driving. The most common problems are worn-out brake pads that are too thin or surfaces contaminated with metal shavings and dust, causing squealing sounds when braking. You can first check the pad thickness yourself - if it's below the safety line, replace them immediately; or rinse the wheel hub with water to remove dirt. If the rotor surface becomes uneven, you'll feel vibrations and hear abnormal noises while driving, requiring professional resurfacing. Another possibility is improper installation, like misaligned pads, which just needs readjustment. I've also encountered noise caused by loose wheel hub bearings - tightening the bolts solved it. Developing good driving habits, avoiding sudden braking, and regularly cleaning brake components during car washes can prevent such issues. Don't ignore problems - minor noises left unattended may lead to brake failure. The safest approach is driving straight to a repair shop when issues arise. Always start with simple checks, because ensuring safe driving is what matters most.
Don't panic when encountering brake noise, try checking it yourself. I usually start by identifying the sound: sharp squealing may indicate worn brake pads needing replacement; dull grinding could mean dirty or oily rotors—just spray some brake cleaner. Steps: After parking safely, check pad thickness (usually inspect the inner wheel side), replace if insufficient (ensure correct model and proper installation). If water rinsing doesn't work, accumulated dust might be the issue—simply clean inside/outside wheels. Avoid abrupt braking/acceleration to prevent pad glazing. Periodically lubricate brake components (avoid oil contamination affecting performance). Address abnormalities promptly—visit a professional shop if DIY fixes fail.
Never ignore any abnormal noises from your brakes, as they are directly related to your driving safety. Based on my experience, such sounds are often early warning signs of issues in the braking system, such as worn-out pads, warped rotors, or loose components colliding. Immediate action is required: when you hear unusual noises, slow down, pull over safely, and inspect the brake components for obvious looseness or contamination. Perform a simple cleanup if possible; otherwise, head to a repair shop immediately. Delaying repairs may lead to brake failure, significantly increasing accident risks, especially during rainy, snowy, or nighttime driving. I recommend keeping a toolkit handy for regular inspections and adopting a zero-tolerance policy towards brake issues. Remember, safety comes first—address problems promptly to prevent minor issues from escalating into major hazards.
