How to Deal with the Noise When Releasing the Brake on a Teana?
2 Answers
Teana's noise when releasing the brake is caused by improper material use or deformation of the brake disc. Normal noise: New cars or newly replaced brake pads may produce noise initially, which is normal because the friction surfaces have not yet matched. Simply driving for a few hundred kilometers will naturally eliminate the noise. Noise after being wet by rain: Brake pads are usually made of iron and can rust when wet from rain. Pressing the brake at this time will cause noise, which can be resolved by grinding off the rust. Noise due to brake pad configuration: Possible causes include incorrectly installed brake pads, missing screws or parts, brake pads that are too small and do not match the friction surface, or the use of cheap brake pads.
My car used to make squeaking noises whenever I released the brake. Later, I found out it was due to severely worn brake pads - they needed replacement when the thickness was less than 4mm. Another common issue is rusted or insufficiently lubricated calipers, especially with the Teana's chassis design which tends to accumulate moisture in humid conditions. I suggest asking a friend to help locate the source of the abnormal noise. If it's coming from the front wheels, it's likely pad or disc related; if from the rear wheels, it could be handbrake-related. After parking, pump the brakes a few times to dry out moisture as preventive maintenance. For self-inspection, you can remove the wheels to check brake pad condition, but never force anything if you're unsure - safety first. If the noise persists or the brake feels spongy, get it professionally inspected immediately to avoid potential hazards. During regular maintenance, have mechanics check the braking system - it's a low-cost measure that ensures safety.
