Introduction
Brakes are the unsung heroes of car safety, ensuring we stop reliably. However, when your car starts squealing during braking, it’s not just annoying—it could signal serious issues that need attention.
Common Causes of Car Squealing When Braking
Worn Brake Pads: Brake pads naturally wear down over time, causing a high-pitched squeal due to metal-on-metal contact.
Contaminated Brake Pads: Oil or grease on the brake pads can reduce friction, leading to squealing. This often occurs from leaks or improper servicing.
Rusty Rotors: Moisture buildup or extended periods of vehicle inactivity can cause rust to form on the rotors, resulting in uneven braking and squealing.
Glazed Brake Pads: Intense heat from frequent hard braking can cause brake pads to glaze over, reducing their effectiveness and causing squealing.
Faulty Brake Caliper: A malfunctioning brake caliper can cause uneven brake pad wear or sticking, resulting in persistent squealing.
Diagnosing the Cause of Squealing Brakes
Inspect brake pads visually for wear and measure thickness as per manufacturer guidelines. For complex issues like faulty calipers, consult a mechanic.
Solutions and Preventative Measures
Replace Brake Pads: The most common fix for squealing brakes due to wear or contamination. Consult a mechanic or follow manufacturer guidelines if attempting DIY.
Resurface Brake Rotors: Smoothes out rotor surfaces to eliminate rust-induced squealing. Replacement may be necessary in severe cases.
Maintain a Safe Braking Distance: Avoid sudden braking to prevent overheating and glazing of brake pads.
Regular Brake Inspections: Schedule routine checks to catch potential issues early and ensure brake system integrity.
Conclusion
Promptly addressing brake noises is crucial for vehicle safety. Ignoring squealing brakes can lead to more costly repairs and compromised driving safety.
For detailed diagnosis and repairs, consult a qualified mechanic. Your safety on the road depends on it.
