What to Do About Squeaky Brake Pads After Water Exposure?
2 Answers
Determine the cause based on the sound of the brake noise: 1. Squealing: First, check if the brake pads are nearly worn out (the wear indicator is making noise). If they are new pads, inspect for any foreign objects caught between the brake disc and pads. 2. Thudding: This is often an issue with the brake caliper, such as worn sliding pins or a detached spring plate. 3. Hissing: The caliper, brake disc, or brake pads could all be problematic. If the noise persists, first check for brake drag, as poor caliper retraction can cause prolonged friction between the disc and pads, leading to noise under certain conditions. Also, inspect for any foreign objects stuck between the pads and disc. If the pads are new, check if the brake disc has grooves, as localized friction can cause noise. Lastly, consider whether the brake pads are too hard or if the noise suppressor was installed incorrectly.
As a veteran driver with decades of experience, I can tell you that brake pads often make squeaking noises after getting wet, mainly because water lubricates the friction surface, causing metal-to-metal contact noise. The solution is simple: gently apply the brakes a few times or drive at low speed for a while to let the friction heat evaporate the moisture. However, if the water ingress is severe or recurring, it may indicate rust on the brake pad surface or material issues, in which case timely replacement is necessary. Pay extra attention during the rainy season—avoid high-speed driving immediately after wading through water to prevent deep water from lingering. Regular brake system inspections can prevent abnormal noises and ensure stable braking performance.
