What to Do When the Lifan 320 Makes Abnormal Noise When Starting and Braking
2 Answers
Reinstall the brake pads and apply butter or special lubricating oil at the connection between the brake pads and the brake caliper. The solutions for the Lifan 320 making abnormal noise when starting and braking are as follows: 1. There may be small metal particles inside the brake pads, which can produce a sharp, piercing sound when lightly braking. You can stomp on the brakes several times or remove the brake pads for re-grinding. Alternatively, you can replace them with better brake pads. 2. Wear on the brake disc can form deep grooves around the disc. Friction between the brake pads and the edges of these grooves can cause abnormal noise. If the grooves are not particularly deep, you can grind the edges of the brake pads to avoid friction with the groove edges. If the grooves are already very deep, the brake disc should be replaced.
I've been driving my Lifan 320 for several years, and it's quite common to encounter abnormal noises when stepping on the brakes during startup. The reason may be due to worn brake pads or the brake pads getting stuck on the brake disc, causing a squeaking sound from friction during startup. I've tried checking it myself—if the brake pad thickness is less than 3 millimeters, they need to be replaced. The cost isn't high, usually just a couple hundred yuan. Sometimes, rust on the disc surface can also cause abnormal noises, especially in humid weather, and spraying some brake cleaner might solve the issue. However, don’t ignore the problem. If the noise persists, it's advisable to visit a reliable repair shop to check if the guide pins are returning properly, to avoid potential brake failure risks in the future. Regular maintenance, such as changing the brake fluid annually and checking lubrication, can significantly reduce such noises.
