What to Do When There's a Squeaking Sound While Braking?
1 Answers
Methods to address squeaking sounds when braking are as follows: 1. Squeaking sound when braking: This could indicate several issues, including problems with the caliper, brake disc, or brake pads. If the sound persists, check for dragging brakes, as poor caliper retraction can cause prolonged friction between the disc and pads, leading to unusual noises under certain conditions. Also, inspect for any foreign objects stuck between the pads and disc. 2. Brake pads are too hard or the anti-noise shim is incorrectly installed: For new pads, check if the brake disc has grooves, as localized friction can cause noise. If the disc is fine, consider whether the brake pads are too hard or if the anti-noise shim was installed incorrectly. Try reinstalling the brake pads and apply butter or specialized lubricant at the connection between the brake pads and caliper to resolve the issue. It's also possible that the brake pads were installed backward; simply reassemble them correctly. This is especially important for owners who had their brake pads replaced at roadside stalls. 3. Noise during rainy days: Rain can also cause brake noise. If the car has been parked for several days, the brake disc and pads may rust and stick together, possibly producing a popping sound upon startup. This is normal and not a cause for concern; a few more brake applications will remove the rust from the disc. Another scenario is a whining sound during low-speed braking, possibly due to water in the brake disc, making the pads and disc damp. The noise should disappear once the water dries.
