Squeaky Brakes on my 2018 XC90 - What's going on?

Vehicle: 2018 Volvo XC90 T6 Momentum

Hey everyone,

I've been noticing a persistent squeaking sound from the brakes on my 2018 Volvo XC90 T6. It's most noticeable at low speeds, especially when I'm coming to a stop or just lightly pressing the pedal. It's not a grinding sound, just a high-pitched squeak.

I've got about 60,000 miles on it, and I don't think the pads have ever been replaced. Could this just be normal wear and tear, or is it something more serious? I'm a bit worried about it.

Any advice on what I should check or if this is a common issue with these models would be greatly appreciated!

ClearTheCode admin answer:

Squeaky brakes are a common complaint and can stem from several issues. Here's a breakdown of potential causes and what to do:

  1. Worn Brake Pads: This is the most frequent cause. Most modern brake pads have a small metal wear indicator that makes a high-pitched squeal when the pads are getting low, signaling it's time for replacement. Given your mileage, this is highly probable.
  2. Glazed Rotors or Pads: If brake pads or rotors get excessively hot, their surfaces can become glazed, leading to squealing. This can sometimes be resolved by proper bedding-in procedures or light machining of the rotors.
  3. Contamination: Dirt, dust, road salt, or even brake fluid/grease on the pads or rotors can cause noise. A thorough cleaning of the brake components can sometimes help.
  4. Improper Installation: If pads or rotors were recently replaced, incorrect installation, lack of anti-squeal shims, or insufficient lubrication on contact points can lead to noise.
  5. Rust: Surface rust on rotors, especially after rain or sitting for a while, can cause temporary squealing until it's worn off after a few stops.

When to See a Shop:

  • Immediate Inspection: Given the mileage and the persistent nature of the squeak, it's crucial to have your brakes inspected by a qualified mechanic as soon as possible. They can accurately assess pad thickness, rotor condition, and overall brake system health.
  • Grinding Noise: If the squeak turns into a grinding sound, stop driving immediately and have your vehicle towed. This indicates metal-on-metal contact, meaning your pads are completely worn, and the rotors are being damaged.
  • Reduced Braking Performance: Any noticeable decrease in braking effectiveness or a change in pedal feel should prompt an immediate professional inspection.

Ignoring brake noise can lead to more extensive and costly repairs, and more importantly, compromise your safety.
