Why Is There a Strange Noise in the Engine Compartment When Braking?

[DiReed]

Here are three possible reasons for strange noises when braking: Issues with the vehicle's brake fluid: The brake fluid may be insufficient or overdue for replacement. Loose brake fluid lines can cause leakage, leading to strange noises in the engine compartment when braking. This situation requires professional repair at a specialized shop. Sand in the brake discs: Generally, a brand-new car should not produce strange noises when braking. If the car hasn't been driven many kilometers and the brakes start making noise, it is likely due to sand or metal particles getting into the brakes. In this case, stepping on the brakes will produce a sharp sound. This can often be resolved by using a high-pressure water jet during car washing. If that doesn't work, the brakes may need to be disassembled for cleaning. Hard brake pads: Some brand-new cars may produce strange noises when braking, especially when braking lightly. This is usually due to the brake pads being made of harder material. The noise often disappears when braking harder. Generally, this situation can be ignored until the brake pads have worn in after some use.
