Is It Normal to Hear Abnormal Noises When Braking and Steering?
1 Answers
Whether it is normal to hear abnormal noises when braking and steering depends on the specific condition of the vehicle. Generally, abnormal noises during braking can be categorized into four situations: a sharp, piercing sound when braking; a dull sound when braking; a hissing sound when braking; and a clattering sound when braking after driving for a while. 1. Sharp, piercing sound when braking: New brake pads and brake discs require a break-in period. When braking, if the hard spots on the brake pads (due to the material of the pads) are being worn, this type of noise may occur, which is normal. However, if this sharp, piercing sound occurs after the brake pads have been used for tens of thousands of kilometers, it usually indicates that the brake pads are nearing their wear limit and are emitting a "warning" sound. If the noise occurs within the normal usage period of the brake pads, it is often due to foreign objects lodged in the braking system. In such cases, apart from the break-in period of new pads, the first step should be to check the brake pads for wear or foreign objects. If the pads are worn out, they should be replaced immediately. If foreign objects are present, remove the pads, extract the foreign objects, and reinstall them. 2. Dull sound when braking: This is often caused by a malfunction in the brake caliper, such as wear on the sliding pins or detachment of the spring clips, which can prevent the caliper from functioning properly. When a dull sound is heard during braking, inspect the brake caliper for worn sliding pins or detached spring clips. If found, replace them promptly. 3. Hissing sound when braking: This type of noise is harder to diagnose, as it could stem from issues with the caliper, brake disc, or brake pads. If the noise is continuous, first check for dragging brakes, as poor caliper retraction can cause prolonged friction between the disc and pads, leading to abnormal noises under certain conditions. If the noise occurs immediately after installing new pads, it may be due to a size mismatch between the new pads and the friction blocks. When a hissing sound is heard during braking, it is advisable to inspect the caliper, brake disc, and brake pads for friction issues. Replace any faulty components as needed. 4. Clattering sound when braking after driving for a while: This noise is typically caused by loose attachments on the brake pads. When a clattering sound is heard during braking, check for loose attachments on the brake pads. The best solution is to either reinforce the attachments or replace the brake pads entirely.
