A loud rattling sound when braking – who hasn’t experienced it? This unpleasant noise can have various causes and should not be ignored. Often, worn brake pads or brake rotors are the reason. However, other parts of the brake system can also cause rattling.
What Does Brake Rattling Mean?
Imagine this: You’re driving your car and want to brake at a red light. But instead of a smooth deceleration, you hear a loud, metallic rattling. This isn’t just unpleasant; it can also be a sign of serious problems with your brake system.
“Brake rattling is often the first sign of wear in the brake system,” explains Master Mechanic Markus Schmidt from Berlin. “Ignoring this warning sign can lead to expensive repairs.”
Common Causes of Brake Rattling:
- Worn Brake Pads: Brake pads wear down over time. If they are too thin, they can cause noises when braking.
- Glazed Brake Rotors: Due to overheating, brake rotors can glaze, meaning their surface becomes hard and smooth. This leads to reduced braking performance and noises when braking.
- Rust on Brake Rotors: Especially after the car has been sitting for a long time or in high humidity, rust can form on the brake rotors. This rust then causes a scraping noise when braking.
- Faulty Brake Calipers: A stuck brake caliper can cause the brake pads to constantly rub against the brake rotor. This not only creates noise but also excessive wear.
Dangers of Ignoring Brake Rattling:
If the brakes are not inspected and repaired despite rattling, this can have serious consequences:
- Reduced Braking Performance: Damaged brakes can significantly reduce the vehicle’s braking performance, potentially leading to an accident in a critical situation.
- Expensive Subsequent Damage: Ignoring the problem can damage other parts of the brake system, driving up repair costs.
- Safety Risk: A functioning brake system is essential for road safety.
What to Do About Brake Rattling?
As soon as you notice rattling when braking, you should immediately visit a workshop. Schnagen should be avoided in this context, as they could only worsen the situation. A car mechanic can determine the cause of the problem and perform the necessary repairs.
How to Prevent Brake Rattling:
- Regular Brake Inspection: Have your brakes regularly inspected at a workshop, especially before long trips.
- Adapted Driving Style: Avoid hard braking whenever possible.
- High-Quality Brake Pads and Rotors: Invest in high-quality brake pads and rotors to extend the lifespan of your brake system.
Conclusion:
Brake rattling is a warning sign you should take seriously. Do not ignore this noise; instead, immediately seek out a workshop to find the cause of the problem and prevent subsequent damage. Remember: A functioning brake system is crucial for your safety and that of other road users! Umgangssprachlich Lärm Krawall when braking can therefore have serious consequences. Therefore, don’t wait too long and have your vehicle checked by a professional!
