Annoying Squealing Brakes on my 2018 Rogue - What's the Cause?

ClearTheCode admin answer:

Squealing brakes are a common issue and can stem from several causes. Here's what to check:

1. Worn Brake Pads: This is the most frequent culprit. Most modern brake pads have a small metal wear indicator that squeals when the pads are low, signaling it's time for replacement. If your pads are thin, they need to be changed immediately.
2. Glazed Rotors or Pads: If the brake components get too hot, the surface of the pads or rotors can become hardened or 'glazed.' This can cause a high-pitched squeal. Sometimes, light sanding of the pads or resurfacing the rotors can fix this, but often replacement is better.
3. Foreign Objects: Small stones, dirt, or debris can get lodged between the brake pad and rotor, causing a persistent squeal. A quick visual inspection might reveal this.
4. Improper Installation or Cheap Pads: If brakes were recently serviced, improper installation (e.g., lack of anti-squeal shims or lubricant) or low-quality aftermarket pads can lead to noise.
5. Warped Rotors: While less common for just squealing, warped rotors can sometimes contribute to noise, especially if accompanied by a pulsation in the pedal.

When to See a Shop:

• If you notice a decrease in braking performance or a pulsating pedal.
• If the squealing is accompanied by grinding, which indicates metal-on-metal contact and severe wear.
• If you're unsure how to inspect your brakes or don't have the tools to do so safely.
• It's always recommended to have a professional inspect your brake system at least once a year or every 12,000 miles for safety.
