What Causes Loud Noises When Brake Pads Get Wet?

[MarleyRose]

The specific analysis of loud noises caused by wet brake pads is as follows: 1. If it's a screeching sound: First, check if the brake pads are nearly worn out (the warning tab is making noise). If they are new pads, inspect for any foreign objects caught between the brake disc and the pad. 2. If it's a dull sound: The issue is often related to the brake caliper, such as worn sliding pins or a detached spring plate. 3. If it's a hissing sound: There could be multiple issues, including problems with the caliper, brake disc, or brake pads. 4. If the noise is continuous: Check for dragging brakes, as poor caliper retraction can cause prolonged friction between the disc and pad, leading to abnormal noises under certain conditions. Also, inspect for any foreign objects stuck between the pad and disc. If the pads are new, examine the brake disc for grooves, as localized friction can cause noise. If the disc is fine, consider whether the brake pads are too hard or if the noise suppression shims were installed incorrectly.
