What to Do When There is Noise While Braking?

[Sophie]

If there is noise while braking, follow these steps: 1. If the car makes abnormal sounds, check whether the brake pads are worn out or if there are foreign objects. If they are worn out, replace them immediately. If there are foreign objects, reinstall them. 2. If the brakes make a low-pitched sound, check whether the brake caliper is worn or if the spring plate has fallen off. If so, replace them immediately. 3. When braking, it is recommended to check whether there are any issues with the friction between the caliper, brake disc, and brake pads. 4. If the brakes make a rattling sound, check whether the brake pad attachments are loose and reinforce or replace the new brake pads. More related information is as follows: 1. When the driver steps on the brake, a new car may emit a sharp sound because the new brake pads and brake discs need to be broken in. When braking, if it happens to wear the hard spots on the brake pads, this abnormal sound will occur. The sound is mainly caused by a fault in the brake caliper. 2. When braking suddenly, it may make a laughing sound. This could be the sound of the ABS during normal operation. The ABS system will always keep the vehicle rolling within the critical locking gap. If there is a continuous rustling sound, first check whether the brakes are dragging. 3. Poor resetting of the caliper will cause long-term friction between the disc and the pad, and in some cases, abnormal noise will occur. If abnormal noise occurs immediately after installing new pads, it may be due to inconsistent sizes between the new pads and the friction blocks.
