Squealing Brembo Brakes on 2022 TLX Type S - Normal or Problem?

Vehicle: 2022 Acura TLX Type S

Hi everyone,

I've got a 2022 Acura TLX Type S, and I'm absolutely loving the performance. However, I've noticed a pretty loud squealing coming from the front brakes, especially at low speeds or when coming to a gentle stop. It's not a grinding sound, just a high-pitched squeal. The car only has about 15,000 miles on it, and I haven't tracked it or driven it particularly hard.

I know performance brakes, like the Brembos on the Type S, can sometimes be a bit noisy, but this seems excessive for such a new car. I'm wondering if this is just a normal characteristic of these brakes, or if it's a sign that something needs attention. I'm used to quieter brakes on my previous cars.

Should I be concerned about pad wear or something else? Any other Type S owners experience this, and what did you do about it? Thanks in advance for your insights!

It's very common for high-performance brake systems, such as the Brembo brakes on your 2022 Acura TLX Type S, to produce some level of squealing, especially at low speeds or during light braking. This is often a normal characteristic and not necessarily a sign of a problem, but it's always good to understand the causes.

Here's why performance brakes can squeal and what to consider:

  1. Pad Compound: Performance brake pads are typically made from harder, more aggressive compounds designed for high friction and heat resistance. These materials can resonate and vibrate against the rotors, creating a squealing sound, particularly when they are cold or not fully warmed up. This is often more pronounced at lower speeds.
  2. Brake Dust Buildup: The aggressive pads also tend to produce more brake dust. This dust can accumulate between the pad and rotor, contributing to noise. Regular cleaning of the wheels and brake components can sometimes help reduce this.
  3. Lack of Proper Bedding-In: When new, brake pads and rotors need to be properly 'bedded in' to transfer a thin layer of pad material evenly onto the rotor surface. If this process isn't done correctly, or if the brakes are consistently used very gently, it can lead to uneven pad material transfer and noise. You might try a proper bedding-in procedure (consult your owner's manual or a performance brake guide).
  4. Anti-Squeal Shims/Grease: While Brembo systems usually come with high-quality anti-squeal shims, sometimes these can fail, or the anti-squeal grease applied during installation can wear off, leading to noise.

When to See a Shop:

  • If the squeal is accompanied by a grinding noise: This indicates metal-on-metal contact, meaning your pads are severely worn down and need immediate replacement.
  • If you feel a pulsation or vibration through the brake pedal: This could suggest warped rotors, which would require inspection and possibly replacement or resurfacing.
  • If braking performance has noticeably decreased: Any reduction in stopping power or a 'spongy' pedal feel warrants immediate professional inspection.
  • If the squeal is constant and extremely loud, even after the brakes are warm: While some noise is normal, excessive, persistent noise might indicate an issue with pad installation, a stuck caliper, or an issue with the anti-squeal shims.

Given your car's mileage, it's unlikely to be significant wear unless you've been extremely hard on the brakes. However, a quick visual inspection by an Acura technician can confirm pad thickness and rotor condition, giving you peace of mind.
