What Causes the Brake Noise in the Envision?
3 Answers
Envision brake noise causes are as follows: Abnormal ABS operation: Normal ABS activation The ABS working process is actually a cyclic process of locking-releasing-locking-releasing, keeping the vehicle in a state of intermittent rolling at the critical locking point. When the ABS is activated by sudden braking, a clunking sound may occur. This noise is normal, and the solution is to press the brake pedal firmly to the floor. Brake pad/disc corrosion: Brake pad/disc rust After prolonged parking, especially in humid climates or after rain, some rust or dirt may form on the brake discs or pads. This issue usually resolves after driving for a while. Alternatively, applying butter or specialized lubricant at the connection between the brake pads and calipers can help. Improper installation: Installation issues If the brake pads are installed incorrectly or the model does not match, noise may also occur. The brake pads should be reinstalled properly. When installing brake pads, owners should have the work done at a professional auto repair shop.
Brake system issues are no small matter. My Envision recently had similar noises, and upon inspection, common causes include excessively worn brake pads or uneven friction surfaces causing abnormal sounds. If the noise is sharp when braking, it might be due to rust or debris on the brake disc surface. The noise is more noticeable when driving through puddles in rainy weather, but this is usually temporary. Additionally, insufficient lubrication of the brake caliper or a stuck piston can cause similar problems. It's advisable to avoid sudden braking and regularly check brake pad thickness—replace them if they're below 3mm. Regular maintenance at a professional shop and choosing high-quality brake pads can significantly reduce noise. Never wait for safety issues to arise—early repairs are affordable and provide peace of mind.
As a car owner, my Envision occasionally makes squeaking noises when braking, especially after a cold start. Common causes include normal noise during the break-in period for new cars; or dust, small stones, and other debris between the brake pads and rotors, which can be resolved by cleaning them; scratches or unevenness on the brake rotors can also cause noise. I regularly check if the brake fluid level is low, as high temperatures can exacerbate issues. If the noise persists, avoid tinkering yourself—it's best to have a professional check if the calipers are loose or the pads are too thin. Developing a habit of lightly pressing the brakes a few times before each drive can help with smoother break-in, extend lifespan, and save money.
