What is the reason for the abnormal noise in the Mazda 3 Axela's brakes?
3 Answers
Abnormal noise during braking is generally caused by issues in the following two parts: 1. Brake pads and brake discs: Severe wear on the pads or discs requires immediate replacement of the brake pads. Additionally, if the dashboard brake warning light is not activated, the sensor connected to the brake warning system should also be checked for issues. 2. Brake system: It is likely that there is a problem with the rubber ring in the brake pump. The abnormal noise may be caused by improper installation or aging of the rubber ring. It is recommended to replace the rubber ring promptly to avoid accidents. Additional information: Common braking misconceptions: 1. Coasting in neutral downhill and relying on brakes for control. 2. Slamming on the brakes during a tire blowout. 3. Applying brakes while waiting at traffic lights. 4. Braking while turning.
I've been driving my Mazda3 for almost two years, and recently there's been this annoying squeaking sound when braking, especially noticeable at low speeds. I think it might be due to worn-out brake pads that have become too thin, causing uneven surfaces or possibly sand particles getting stuck in them. Last time at the repair shop, the mechanic said common causes for such noises also include rust on brake discs, particularly after driving in rainy conditions when moisture accelerates corrosion. If there are scratches on the disc surface, the pads will wear unevenly and produce noise. He suggested first checking the pad thickness – it should normally be above 2-3mm; if thinner, they need replacement. Then feel the disc surface for smoothness – any roughness requires resurfacing. Avoid slamming on brakes during daily driving, and have them clean out debris during regular maintenance. Safety comes first – don't let the noise persist and affect braking performance. After getting mine fixed, the car runs quietly now.
As a veteran driver with over a decade of experience, I've encountered numerous brake noise issues. The Mazda 3 (Axela) has a well-designed braking system, but noises are often minor problems. I suspect most cases are caused by excessively hard brake pad materials or uneven wear leading to squealing, or newly replaced pads making clunking sounds before proper break-in. Warped rotors or rust can also be factors, especially after driving through mud or rain when corrosion affects the rotor surface. Additionally, loose installation or screws can cause rattling noises during vibration. My suggestion: first check pad thickness - replace immediately if under 3mm; then inspect rotors for grooves - minor scratches can be polished out. For maintenance, avoid high-pressure car washes that force water into brake areas, and regularly check screw tightness at shops. Don't casually dismiss others saying "it's nothing" - increased stopping distance could be dangerous. My car had no issues after timely repairs.
