Sizzling while braking is a fairly common problem that can be caused by a variety of factors. Here are some possible reasons and their solutions::
Brake pad wear: Brake pads that are used for a long time may wear out severely, resulting in sizzling noises while braking. The solution to this problem is to replace the brake pads with new ones.
Brake pads and discs do not match: If the pads and discs do not match the material, it may also make noise when braking. This problem can be solved by replacing a suitable brake pad or brake disc.
Rust on the surface of the brake disc: For vehicles that have been parked for a long time, the surface of the brake disc may rust, which will make a sizzling sound when braking. Removing rust from the brake disc solves this problem.
Excessive dust in the brake system: Dust and impurities accumulated in the brake system can also cause noise when braking. Cleaning the brakes regularly can avoid this problem.
Insufficient or aged brake fluid: Insufficient or aged brake fluid may affect the normal operation of the brake system, resulting in sizzling sounds. Adding or replacing brake fluid in a timely manner is the key to solving this problem.
Loose brake parts: Loose parts in the brake system may also make noise when braking. Inspecting and tightening loose parts can eliminate this noise.
Effect of high temperatures: When driving at high speeds or using the brakes for a long time, the braking system may sizzle due to excessive temperatures. Appropriately reducing the use of brakes and avoiding overheating can solve this problem.
Use inferior or stiff brake pads: Inferior or stiff brake pads may sizzle when rubbing against the brake disc. Replacing with a good-quality, suitable brake pad can solve this problem.
Foreign objects between brake pads and brake discs: During driving, sand or other foreign objects may enter between the brake pads and brake discs, causing a sizzling sound when braking. Cleaning up these foreign objects can eliminate noise.
To sum up, when the brake sound is found, the owner can first check the above possible reasons, if the cause cannot be determined or the problem is solved, it is recommended to go to a professional car repair shop for inspection and repair as soon as possible to ensure driving safety.
