Signs of Failing Brake Hardware
Worn or corroded brake hardware can ruin the quiet ride of your Lexus. The symptoms are often mistaken for bad brake pads, but these small clips are usually the cause of brake noise. Look for these common signs.
- Braking Noises: High-pitched squealing, screeching, or rattling sounds when you apply the brakes are the most common signs of failure. This happens when the clips lose tension and let the brake pads vibrate.
- Uneven Pad Wear: If hardware is rusted or bent, it can cause a brake pad to stick. This leads to one pad wearing out much faster than the others.
- Pulling to One Side: When brake parts on one wheel stick, it can cause your car to pull to the left or right when you brake.
Known Issue: Front Brake Squeal TSB
Lexus released a Technical Service Bulletin (TSB L-SB-0008-22) for some 2019-2022 ES300h models that may have a squeak or squeal from the front brakes. The official repair is to install an updated hardware kit. If you hear a squeal from the front of your car, replacing the hardware with a new kit during your next brake service is the recommended fix.
Choosing the Right Aftermarket Hardware Kit
You do not need to buy hardware from a Lexus dealer to get good quality. Because these parts are inexpensive, it is always recommended to choose a quality aftermarket option. Reusing old hardware is never a good idea, as it can be corroded and will have lost its spring tension.
Pro Tip: Always replace your disc brake hardware kit every time you replace your brake pads. It is the best way to prevent brake noise and ensure your new pads wear evenly.
Brand Quality Tiers
For your ES300h, several aftermarket brands provide reliable quality. The brands below are good alternatives to the more expensive OEM parts.
- Beck Arnley: This brand specializes in parts for imported vehicles like your Lexus. Beck Arnley often sources its parts from the same companies that make the original factory parts. This means you can get OEM-level quality for a lower price. It is generally considered a high-quality choice for Japanese vehicles.
- Dynamic Friction (DFC): Dynamic Friction is a well-regarded aftermarket brand that offers a wide range of brake components. Their hardware kits often feature anti-corrosion coatings that help them last longer, which is a valuable feature. User reviews are generally positive, citing good fit and performance for daily driving.
Cost of Replacing Your Brake Hardware
The hardware kit itself is very affordable. The main cost will be the labor for the brake job, as the hardware is replaced at the same time as the pads.
| Part Type | Price Range (Part Only) |
|---|---|
| New Aftermarket Hardware Kit | $9.35 - $29.32 |
| New OEM Lexus Hardware Kit | $25 - $50 |
| Shop Labor (for brake job) | $110 - $186 per axle |
Frequently Asked Questions (FAQ)
Do I have to replace the hardware with every brake job?
Yes, it is highly recommended. Old hardware loses its tension and can be corroded. For a small cost, a new hardware kit ensures your new brake pads work correctly and quietly. It is cheap insurance against noise and premature wear.
What is included in a disc brake hardware kit?
A typical kit for your Lexus ES300h includes a set of anti-rattle clips (also called abutment clips) and sometimes pad-spreader springs for one axle (either both front wheels or both rear wheels).
Can failing brake hardware cause damage?
While the hardware itself is unlikely to cause major damage, it can lead to problems. Sticking hardware can cause brake pads and rotors to wear out much faster, leading to more expensive repairs. In severe cases, a grinding noise means the pads are gone and the rotors are being damaged.
Is there a recall on the brake hardware for my ES300h?
No, there are no recalls for the disc brake hardware. There have been recalls on other parts of the brake system, like the brake booster pump, for some model years, but not the clips and springs. However, there is a Technical Service Bulletin (TSB) for brake squeal that is fixed by replacing the hardware.
