Vehicle: 2020 Chevrolet Equinox LT

Hey everyone, I'm having a really annoying issue with my 2020 Chevrolet Equinox LT. About two months ago, I had the front brake pads and rotors replaced at a local shop because they were worn down. Ever since then, I've been getting this persistent, high-pitched squeak from the front brakes, especially when coming to a stop at low speeds.

It's not a constant squeal, but definitely noticeable and quite embarrassing in traffic. I've tried bedding them in again, but it hasn't helped. The shop said they used good quality pads and rotors. Is there something they might have missed, or is this just a common thing with new brakes on an Equinox?

Any ideas on what could be causing this or how to get rid of the noise? It's driving me nuts!

Hi Sarah,

Persistent squeaky brakes after a pad and rotor replacement on your 2020 Chevrolet Equinox can be frustrating, but it's a common complaint. While new brakes often make some noise during the bedding-in process, a continuous high-pitched squeak at low speeds suggests a few potential issues that might need attention.

Here are the most common causes and what to check:

  1. Improper Installation or Lubrication:

    • Cause: Brake components require proper lubrication at specific contact points. If the caliper slides, pad backing plates, or shims weren't adequately lubricated with high-temperature brake grease, metal-on-metal contact can occur, leading to squealing.
    • Check: Ensure the caliper guide pins move freely and are greased. Also, check that anti-rattle clips are correctly installed.
  2. Pad Material or Quality:

    • Cause: Some brake pad compounds, particularly metallic or semi-metallic pads, can be more prone to noise than ceramic pads. Lower quality pads might also be more susceptible to squealing.
    • Consideration: While the shop stated they used good quality parts, sometimes specific brands or compounds can be noisier on certain vehicles.
  3. Rotor Finish:

    • Cause: If the rotors weren't properly cleaned before installation, or if they have an uneven surface finish, it can contribute to noise. Also, if the rotors were not 'bedded in' correctly with the new pads, it can cause issues.
  4. Brake Shims:

    • Cause: Shims are thin plates placed between the brake pad and the caliper piston to absorb vibrations and reduce noise. If they are missing, damaged, or incorrectly installed, squealing can occur.
  5. Caliper Issues:

    • Cause: A sticking caliper piston or guide pin can cause uneven pad wear and constant contact with the rotor, leading to noise. This is less likely with new pads/rotors but worth considering if other solutions fail.

When to See a Shop:

  • Return to the original shop: Since the issue started immediately after their work, the first step should be to return to the shop that performed the service. Explain the persistent squeak and ask them to re-inspect the installation, lubrication, and components. Most reputable shops will address post-service issues like this under warranty.
  • If the noise changes or worsens: If you notice any changes in braking performance, a grinding noise, or if the squeak becomes louder or more frequent, have it inspected immediately to rule out any safety concerns.
