How to Solve Brake Pad Squealing?

[CaliDella]

First, observe the location of the brake squealing. The majority of brake squealing originates from the brake pads, accounting for over 80% of cases. Brake pad squealing is usually caused by worn-out pads scraping against the rotor, which indicates the need for pad replacement. Here are explanations regarding brake pad squealing: 1. Approximately 10% of brake squealing is caused by issues with the brake rotor, typically due to rotor warping. This creates a wobbling motion that grinds against the brake pads while driving, producing noise. This situation can be resolved simply by resurfacing or grinding the rotor. Another common scenario is light rust formation on rotors from prolonged vehicle inactivity, causing squealing when pads contact the rust. This requires no special concern - just normal driving for a period will wear off the surface rust. 2. Another 10% of brake noise stems from loose brake shields, improper reassembly after service, or component damage from impacts. Diagnose and repair based on the specific sound characteristics of the brake squealing.
