1. Improper Installation: Ensure the brakes, rotors, and calipers were installed correctly. If the components are not properly seated or aligned, it can cause squealing.
2. Brake Pad Compatibility: Confirm that the brake pads used are compatible with your vehicle's model. Different brake pad materials may have varying levels of noise production.
3. Glazed Brake Pads: If the brake pads have become glazed, it can lead to squealing. Glazing occurs when a thin layer of glass-like material forms on the brake pad surface due to excessive heat or improper bedding.
4. Contamination: Check for any contaminants (dirt, grease, oil) on the brake pads, rotors, or caliper pistons. Contamination can cause brake squealing. Clean the affected components with brake cleaner if there's any.
5. Improper Lubrication: Incorrect application of lubrication to brake components (such as caliper guide pins) can lead to squealing.
6. Brake Pad Thickness: If the brake pads are too thin, they may not have sufficient contact with the rotors, causing squealing.
7. Caliper Issues: Problems with the caliper, such as misalignment, sticking caliper pistons, or a damaged caliper, can also cause squealing.
8. Rotor Quality: Low-quality rotors that are not properly manufactured may be more prone to noise issues, including squealing.
Recommendations:
1. Return to the Garage: Since you've recently had the work done, it's best to return to the garage that installed the brakes. They should rectify any potential issues related to installation or component compatibility.
2. Proper Bedding-In Process: Follow the recommended bedding-in process provided by the brake manufacturer. This process helps to remove any contaminants from the brake pads and rotors and ensures proper engagement.
3. Avoid Heavy Braking: During the initial bedding-in period, avoid heavy braking or excessive use of the brakes to prevent glazing and potential squealing.
4. Lubricate Caliper Pins: If the garage didn't apply lubrication during installation, ask them to do so and ensure they use the appropriate lubricant specified by the vehicle manufacturer.
5. Seek a Second Opinion: If the issue persists, seek a second opinion from a reputable mechanic or brake specialist to identify any underlying issues that might be causing the brake squealing.
