What Causes the Rumbling Sound When Braking at High Speed?
1 Answers
High-speed braking with a rumbling sound is typically caused by an issue with the brake caliper. Below are specific explanations regarding abnormal brake noises: 1. Squealing Noise: First, check if the brake pads are nearly worn out. For new brake pads, inspect whether the brake disc has grooves, as localized friction can cause abnormal noises. If the brake disc is fine, consider whether the brake pads are too hard, if the anti-noise shims are incorrectly installed, or if there are foreign objects trapped between the brake disc and pads. 2. Hissing Noise: A hissing noise can indicate various issues, potentially involving the caliper, brake disc, or brake pads. 3. Continuous Noise: If the noise persists, check for dragging brakes. Poor reset of the brake caliper can cause prolonged friction between the brake disc and pads, leading to abnormal noises under certain conditions.
