1. Brake pad wear: As brake pads wear down, they can become thin and make a squealing noise when they rub against the rotors. This is a common cause of brake squeal and can be fixed by replacing the brake pads.
2. Contamination: Brake pads and rotors can become contaminated with dirt, grease, or other substances that can cause them to squeak. Cleaning the brake pads and rotors can often fix this problem.
3. Misalignment: If the brake pads are not properly aligned with the rotors, they can make a squealing noise. This can be fixed by adjusting the brake pads.
4. Glazed rotors: Brake rotors can become glazed over time, which can cause them to squeak. Resurfacing the rotors can fix this problem.
5. Incorrect brake pads: Using the wrong brake pads for your vehicle can cause them to squeak. Make sure you are using the correct brake pads for your vehicle.
6. Loose or worn brake components: Loose or worn brake components, such as caliper bolts or pins, can cause a squealing noise. Tightening or replacing the loose or worn components can fix this problem.
