Why Do Newly Replaced Brake Pads Make Noise?
2 Answers
Newly replaced brake pads may produce abnormal noises for the following reasons: 1. Check if there are any foreign objects caught between the brake disc and pads. If the noise is a dull sound, it is mostly due to issues with the brake caliper, such as worn guide pins or detached spring plates. If the noise is a high-pitched squeal, there could be multiple problems, including issues with the caliper, brake disc, or brake pads. 2. If the noise persists, first check for any dragging brakes. Poor caliper retraction can cause prolonged friction between the disc and pads, leading to abnormal noises under certain conditions. Also, inspect whether any foreign objects are stuck between the pads and disc. 3. If the pads are new, check if the brake disc has grooves. Localized friction can cause noise. If the disc is fine, consider whether the brake pads are too hard or if the anti-noise shims were installed incorrectly.
I just got new brake pads installed, and my car squeaks every time I hit the brakes—it’s driving me crazy. After some research, I learned this is usually normal. New pads have a coating or uneven surfaces that need to wear in against the rotors, and the noise should fade after a few hundred kilometers. If the squeaking persists, it might be due to leftover dust or debris trapped during installation, or insufficient lubrication. Last weekend, I took a highway drive on purpose, and the noise reduced noticeably. Remember, don’t rush to disassemble them at the first squeak—monitor it for a few days to see if it changes, or you might waste money on unnecessary repairs. If you’re still uneasy, have a shop check the rotor’s condition—safety first!
